Product Technology & Safety
The technology behind MELTRIC’s products was developed specifically to address the shortcomings and safety hazards common with pin & sleeve type plugs and receptacles. In 1952, following the observation of an accident with a pin and sleeve device, Gilles Marechal devised the concept of combining the advantages of silver-nickel butt contacts and the load making and breaking capabilities of a switch with the convenience of a plug and receptacle. Shortly thereafter, the first of these products was born. MELTRIC licensed this technology in the early 1980’s and has been supplying its products to North American customers ever since.
highest quality and most reliable plugs and
receptacles, and by backing them with
outstanding service and support.
Value
With their unique features and capabilities, MELTRIC products provide users with a safer and more reliable product than competitive pin and sleeve devices. MELTRIC’s butt-style contacts provide longer operating lives, optional integral pilot contacts reduce the need for additional connectors and our switch-rated plugs and receptacles can eliminate the need for auxiliary interlocks and disconnect switches, helping users reduce equipment costs.

Spring-Loaded Butt Contacts
MELTRIC products feature spring-loaded, butt contacts similar to those used in contactors and switchgear. These contacts have numerous advantages, which help improve electrical performance and user safety relative to pin and sleeve contacts or the arcuate contacts used in twist-type devices.
Butt-style contacts ensure a very positive and consistent connection. The spring-loading of these contacts, which is accomplished with coil springs, provides a desirably high contact force that remains constant over thousands of operations. In addition, it automatically compensates for any wear and/or deviations in contact length resulting from manufacturing tolerances.
This is a critical point, as contact force is a key determinant of the quality of a contact. As the accompanying chart demonstrates, contact resistance increases as contact force is reduced. Higher contact resistance generates more heat

and oxidation, both of which contribute to the deterioration of the contact. This is a problem with pin and sleeve and arcuate type contacts because their contact force varies with manufacturing tolerances and is reduced due to wear that occurs with normal use.
Most MELTRIC contacts close with a self-cleaning wiping action. When the contacts initially mate, they are slightly offset. In completing the connection, the plug contacts are rotated across the receptacle contacts, helping to remove deposits from the contact surfaces.
In conjunction with the ejection springs used on many MELTRIC products, the spring-loaded contacts ensure a quick breaking of the connection that is independent of the motion of the user. By contrast, the disconnection speed of pin and sleeve and twist-type devices is dependent upon the motion of the user.

...AND BENEFITS
Silver-Nickel Contact Material
MELTRIC uses solid silver-nickel (85%/15%) contacts. The silver-nickel material has significant advantages over the brass contacts commonly used on competitive devices.
Silver has very low initial contact resistance and is not negatively affected by oxidation. This helps to give it excellent electrical properties that are maintained even at high temperatures and after tarnishing. Nickel is a much harder material and contributes excellent mechanical properties. The combination of silver and nickel results in a contact material that has both superior electrical capabilities and excellent resistance to wear. Silver-nickel only welds at extremely high pressure and temperature, and thus, also withstands arcs very well. These features make silver-nickel a commonly used contact material by switchgear manufacturers.
By contrast, the brass material used in most competitive plug and receptacles has a much higher initial contact resistance and is negatively affected by oxidation. In an oxidized state, the contact resistance of brass is more than 20 times higher than that of silver-nickel. In addition, brass is a soft material that wears rapidly. In use, brass pin and sleeve and arcuate contacts suffer from the combined effects of the limitations of the material and the design. As oxidation and wear induced reductions in contact force occur, contact resistance increases. This increases operating temperature, which causes further oxidation and wear, perpetuating a vicious cycle of degradation. Brass is not arc resistant and is not suitable for making and breaking under load.

Dead Front Construction
Most MELTRIC products feature dead front construction, which greatly enhances safety by eliminating any unintended access to live parts. On most MELTRIC products, the dead front is accomplished with a safety shutter that can be opened only by an appropriate mating plug. The live receptacle contacts can only be accessed by the plug, after its insertion into the receptacle. The design of the product also ensures that the plug contacts are dead before the user can remove the plug from the receptacle.
By contrast, pin and sleeve and twist-type devices do not have a safety shutter. Access to live receptacle contacts is possible, and on some devices the plug contacts may be live and accessible when the plug is being removed.

MELTRIC PRODUCT FEATURES...
Push-Button Circuit Disconnection
To disconnect most MELTRIC products, the user simply needs to press the pawl. This causes the circuit to be disconnected and the plug to be ejected to its rest (off) position in the receptacle. If desired, the user can then remove the plug from the receptacle by rotating it slightly and then withdrawing it. This mode of operation ensures that it is only possible to remove the plug after its contacts have been de-energized.
Enclosed Arc Chambers
The contacts on most MELTRIC products make and break within enclosed arc chambers. This ensures that the arcing which normally occurs during the making and breaking of the contacts is contained inside the device. This greatly enhances safety and avoids potential injury to users and/or harm to the outside environment.
Optional Auxiliary/Pilot Contacts
Many MELTRIC products are available with optional auxiliary/ pilot contacts. These integral pilot contacts allow users the convenience and flexibility of controlling auxiliary equipment, monitoring parameters (such as motor temperature), and/or communicating alarms through the same plug and receptacle used to supply power to the equipment. Because the pilot contacts are integral, they also facilitate the rapid change-out or reconfiguration of equipment by eliminating the need for hard wiring or multiple plug connections.
Automatic Watertightness
On most pin and sleeve devices, an additional plastic ring must be tightened in order to ensure the achievement of rated watertightness. Users frequently fail to do this, resulting in leakage. MELTRIC solves this problem with its DS and DSN Switch-Rated plugs and receptacles, which achieve their rated watertightness of up to Type 4X/IP69/IP69K simply by mating the plug with the receptacle. After the removal of the plug, rated watertightness is maintained for the receptacle by sim­ply closing the lid.

...AND BENEFITS
Spring-Assisted Terminals
The loosening of terminal screws is a common cause for failure on standard plugs and receptacles. MELTRIC provides a more permanent and secure connection with its unique and patented spring-assisted terminal design.
As the terminal screw is tightened against the conductor, the associated pressure expands the split terminal body, causing a spring ring surrounding the terminal to deform into an elliptical shape. The natural tendency for the spring ring to return to its original size and shape ensures that a constant pressure is maintained on the conductor. This allows the terminal to effectively compensate for strand settlement and conductor yield, due to cold flow of the material, and provides superior resistance to vibration, shock and thermal cycling.
Lockout-Tagout Capability
SPLIT TERMINAL (allows constant force)
ELLIPTICAL DEFORMING RING (prevents loosening)
CONDUCTOR
Most MELTRIC plugs and receptacles facilitate compliance with OSHA lockout-tagout requirements. Only a lock or lockout hasp and tag are needed to ensure that the plug is properly locked out and tagged out. Additional mechanisms are not required because the lockout provision is integral to the device – it is always available when you need it. On most models the lockout provision is a simple 5/16” hole in the plug shroud that facilitates the insertion of a typical padlock or lockout hasp which prevents the plug from being inserted into a receptacle.
An optional provision for locking out MELTRIC receptacles is also available. In most cases this is accomplished via a specially machined hole in the receptacle casing which allows insertion of a padlock to secure the receptacle lid in a closed position. This same optional provision can be used to prevent removal of the plug if desired.
By comparison, in order to lockout most competitivepin and sleeve type plugs, an additional third-party ‘lockout shield or ‘plug cap’ is required. These devices can be expensive and are often times lost, broken, or not available when you need them.
Modular Construction
Due to the robust construction of MELTRIC devices, the need to replace worn parts is rare. However, should they be required, parts are readily available and reasonably priced. The modular construction of most MELTRIC devices enables easy replacement of parts in the field.

Switch and Hp Ratings
MELTRIC Switch-Rated products are a combination plug, receptacle and non-fusible disconnect switch in the same device. Their integral switch technology ensures the safe breaking of resistive and inductive loads (up to 100 hp or 200 A) before an operator can physically remove the plug from the receptacle.
They are UL and CSA approved for both “branch circuit” and “motor circuit” disconnect switching, making them ideal for connecting motors, welding machines and virtually any other electrical equipment.
Short Circuit Ratings
MELTRIC Switch-Rated plugs and receptacles help ensure worker safety even in fault conditions. They are rated to close into and withstand short circuit currents of up to 100 kA. The protection far surpasses that offered by other plugs and receptacles, and even surpasses the short circuit protection offered by most manual motor controllers and mechanical interlocks.

BENEFITS OF USING MELTRIC SWITCH-RATED DEVICES
Ensure Worker Safety
Switch-Rated plugs and receptacles ensure safety by eliminating hazards associated with pin and sleeve and twist-type devices.
uThe integral switching function ensures that the plug contacts are de-energized before an operator can remove the plug from
the receptacle. The dead-front design prevents unintended access to live parts.
uSpring-loaded, silver-nickel butt-style contacts maintain proper contact force, withst and arcing, resist wear, and maintain
low contact resistance. This ensures the integrity of the connection over thousands of operations and eliminates performance and safety problems common to plugs with brass contacts.
uSpring-loaded plug and receptacle disengagement with push button operation ensures fast and easy load breaking, which
minimizes arcing during disconnection. Enclosed arc chambers eliminate arc flash hazards.
uHorsepower, switch, and short-circuit ratings provide additional protection during locked-rotor or other significant overload situations.
Simplify Code Compliance
Switch-Rated devices provide a simple and cost-effective means of helping facilities to achieve compliance with the National Electrical Code and NFPA 70E.
NEC Compliance
Articles 430.101 to 430.113 of the National Electrical Code regulate the means of motor disconnection (Canadian Electrical Code section 28-600–28-604). They require motors to have readily accessible, ‘line of sight’ disconnects that are an approved switch or a properly rated plug and receptacle.
u430.102 A disconnecting means must be located in sight of
the motor and driven equipment.
u430.107 The disconnecting means must be readily accessible.
u430.109 The disconnecting means may be an approved
switch or horsepower rated plug and receptacle.
MELTRIC Switch-Rated plugs and receptacles are both horsepower and switch-rated. They can function as a ‘line of sight’ disconnect in addition to providing a convenient plug and play power connectionfor the motor. Installing a switch-rated device eliminates the need for an auxiliary disconnect switch.
NFPA 70E (CSA Z462)
This OSHA consensus standard covers electrical safety-related work practices and procedures for employees who work on or near exposed energized electrical conductors or other live circuit parts. Relevant requirements include:
Power must be proven to be off before work can be performed. This requires:
u The safe interruption of the load and opening of
the disconnect
uVisual verification/voltage testing to ensure de-energization
The potential electrical hazard must be identified and documented.
uAn arc flash risk assessment must be performed
uFlash protection boundaries must be determined
Appropriate steps must be taken to protect persons working near live parts or within the flash protection boundary.
uPPE must be worn based on incident energy exposure
levels (cal/cm2)
uOnly properly qualified persons are allowed to perform work
19
...THROUGHOUT YOUR FACILITY
Wiring and connection systems utilizing conventional switches and/or pin & sleeve devices would typically require all of the previously listed protective measures to comply with NFPA 70E or CSA Z462. By using MELTRIC Switch-Rated plugs and receptacles to connect equipment, users can very simply comply with these requirements.
Switch ratings ensure the safe interruption of the load. Visual verification that the power is off is provided when the plug is removed from the receptacle. A dead front design prevents an operator from being exposed to live parts, eliminating the need to perform hazard analysis, establish flash protection boundaries and use electrical personal protective equipment.

Reduce Equipment and Installation Costs
The ability of MELTRIC Switch-Rated devices to safely make and break under full load eliminates the need for the expensive interlocks that are required with pin and sleeve devices. Their ability to function as the NEC required ‘line of sight’ disconnect switch eliminates the need for auxiliary disconnect switches. Optional pilot contacts can eliminate the need of auxiliary connectors in control circuits.
Reduce Equipment Change-out Downtime and Cost
Using MELTRIC Switch-Rated plugs and receptacles to connect motors and other equipment instead of hard-wiring can help reduce equipment change-out time by as much as 50%. With new motors pre-wired with MELTRIC plugs or inlets, the only electrical connection required during the change-out will be to plug in the new motor. Thus, a mechanic will be able to perform the change­out without the immediate aid of an electrician. This avoids the inconvenience of scheduling an electrician for a service call. So, extra downtime required to do the wiring is eliminated. The pre-wiring of replacement motors with MELTRIC plugs or inlets can be done off-site and during the convenience of non-downtime periods. This makes MELTRIC plugs and receptacles an ideal choice for ‘plug and play’ and modular process applications.
