Fixed circuit breaker

Tmax XT circuit breakers are available in the following versions:

FIXED. These have a current-interrupting part connected to the trip unit, to be installed on the

back plate of the box;

PLUG-IN. These have a moving part and a fixed part. The latter must be installed on the back

plate of the box. The moving part comes in the kit that converts the fixed version into a plug-in version;

WITHDRAWABLE. These have a moving part and a fixed part, equipped with side runners to

allow easy racking in/out of the moving part. The fixed part is installed on the back plate of the box. The moving part comes in the kit that converts the fixed version into a withdrawable version. To create the withdrawable circuit breaker, it’s necessary to order a front accessory to

maintain the IP40 degree of protection over the circuit breaker’s entire isolation run. If the plug-in circuit breaker is fitted with electrical accessories, appropriate connectors for insulating the corresponding auxiliary circuits must also be ordered. For the withdrawable version, there are dedicated accessories fitted with connectors enabling automatic disconnection when racking-out. (Consult the “Connectors for electrical accessories” section of this chapter). Using the fixed version as a base, SACE Tmax XT circuit breakers can easily be converted into plug-in and withdrawable versions with the appropriate conversion kits. The moving part can always be obtained in the required version, fully pre-engineered in the factory, by ordering the fixed circuit breaker and the conversion kit at the same time.

Fixed part of plug-in and withdrawable versions

The fixed parts of the plug-in/withdrawable versions are available with extended front terminals (EF). The fixed parts can be equipped with some of the same terminal, terminal-cover and phase barrier kits used for the fixed circuit breakers, by using the proper adapter. The fixed parts of a plug-in/withdrawable circuit breaker can be installed at a distance of 50mm/1.97in from the back of the panel or at 70mm/2.76in as shown in the picture.

Conversion kits

The following conversion kits can be obtained in order to create the different versions:

Kit for converting the fixed circuit breaker into the moving part of plug-in/withdrawable

versions. When withdrawable versions are made, it is essential to order an accessory to apply to the front of the circuit breaker in order to maintain the IP40 degree of protection over the entire isolation run. This accessory can be chosen from: – front for lever operating mechanism (FLD); – motor operator (MOE); – direct or extended rotary handle operating mechanisms (RHD or RHE).

If no accessory is indicated, the front for lever operating mechanism (FLD) is automatically

included in the order.

Kit for converting the fixed part of plug-in versions into the fixed part of withdrawable

versions. The kit comprises: – a guide for turning the fixed part of the plug-in circuit breaker into the fixed part of the

withdrawable circuit breaker;

– a racking-out rotary handle that allows the moving part to be inserted and withdrawn. The

mechanism allows the circuit breaker to be set to the isolated position (with the power and auxiliary circuits disconnected) with the compartment door closed, for operator safety. The rotary handle can only be inserted when the circuit breaker is open. Once it has been removed or withdrawn, the circuit breaker can be set to the open/closed position;

– a flange for the compartment door, which replaces the one supplied with the fixed version of

the circuit breaker.

Kit for converting fixed type into the plug-in version for RC Sel residual current devices

for XT2-XT4. RC Sel four-pole residual current devices for XT2 and XT4 can be converted from the fixed version into the plug-in version using the special kit.

Kit for converting plug-in types into the withdrawable version for RC Sel residual current

devices for XT2-XT4. RC Sel four-pole residual current devices for XT2 and XT4 can be converted from the plug-in version to the withdrawable version using the special kit, which comprises a bellows to apply to the front of the residual current device so as to allow it and the residual current part to be withdrawn when the panel door is closed. This kit can also be assembled on fixed circuit breakers fitted with the front part for locks or the direct rotary handle, thus adding to the range of uses for residual current devices.

In the plug-in to withdrawable conversion kit, there is also a 6-pin connector to be applied onto

the right side of the circuit breaker to facilitate disconnecting the auxiliary circuits connected to the residual current device.

This kit contains also the shunt opening release of the residual current device dedicated to the

withdrawable version, which is fitted with a connector for the fixed part and the moving part.

Connection terminals

Connection terminals allow the circuit breaker to be connected to the system in the way best suited to the installation requirements. By and large, they consist of front terminals for connecting cables or busbar directly from the front of the circuit breaker. Where possible, the terminals have laser markings on the surface to indicate the tightening torques for the correct isolation of cables and bars.

Fixed version

Standard SACE Tmax XT circuit breakers for UL and CSA are supplied with front terminals (F). However, they can be fitted with the following types of terminal as accessories thanks to the special kits:

extended front (EF);

extended spread front (ES);

front for copper/aluminum cables (FCCuAI), for XT3 and XT4 sizes;

front for copper cables (FCCu);

multicable for copper cable (MC);

for flexible busbar (FB);

rear oriented (R)1). For XT1 and XT3 sizes, the use of non-insulated busbar with Ue ≤ 480V involves the mandatory assembly of terminal-covers HTC.

Plug-in and withdrawable versions

The fixed part of plug-in and withdrawable version circuit-breakers is normally supplied with extended front terminals (EF) or horizontal/vertical rear terminals (HR/VR). Horizontal/vertical rear terminals (HR/VR) are factory-mounted in the horizontal position. If needed, the terminals can easily be field-rotated to the vertical position. A fixed part with front terminals (EF) can be converted into a fixed part with rear terminals

(HR/VR) by ordering the appropriate terminal kit. The fixed parts can also be fitted with some of the same types of terminal available on the fixed circuit breaker after an adapter has been installed on the terminal zone of the fixed part itself. Consequently, the following types of connection terminals are also acceptable for use with the fixed part:

extended spread front (ES);

for copper cables (FCCu);

multi-cable (MC).

for copper and aluminum cables (FCCuAl);

for flexibar (FB). The adapter mimics the terminal zone of the fixed circuit breaker. This means that fixed parts can also be equipped with the same terminal covers and phase separators as those used for fixed circuit breakers.

Terminal covers and phase barriers

Terminal covers are applied to the circuit breaker to prevent accidental contact with live parts, thereby providing protection against direct contacts. The high terminal covers are pre-punched for knock-outs on the front to facilitate installing busbars and/or cables and ensuring correct insulation. The phase barrier partitions increase the insulation characteristics between the phases on a level

Rotary handle operating mechanism

This device allows the circuit breaker to be operated by means of a rotary handle, which makes the circuit breaker easier to open and close. Different types of handle are available:

direct (RHD): installed directly on the front of the circuit breaker. Allows it to be operated from

the front;

extended (RHE): installed on the panel door. Allows the circuit breaker to be operated by

means of a rod which acts on a base installed on the front of the circuit breaker;

side, for lateral left (RHS-L) and lateral right (RHS-R). Allows operation from the side by means

of a shaft which acts on the base installed on the front of the circuit breaker.

All rotary handles are available in two versions:

standard: grey color;

emergency: red on a yellow background. Suitable for operating machine tools.

Rotary handles can be ordered:

by specifying one single sales code (for RHD, RHE, RHS L/R);

by indicating the following three devices (only for RHE):

– rotary handle on compartment door with normal standard handgrip (RHE_H, RHE_H LH)

or emergency handgrip (RHE_H_EM, RHE_H_EM LH);

– 60.5mm/2.38" and 170.5mm/6.71" rod (RHE_S). The minimum and maximum distances

between the fixing plate and the door are 60.5mm/2.38" and 170.5mm/6.71";

– base to fix to the circuit base (RHE_B).

Using the rotary handle is an alternative to the motor operator and to all accessories of the front type. The rotary handles can be locked by means of a vast range of key locks and padlocks (consult the “Locks” section of this chapter). The direct and extended rotary operating mechanisms allow early contacts to be used on closing in order to supply the undervoltage release in advance of the circuit breaker's closing (consult the “Early auxiliary contacts” section of this chapter).

Service releases

Shunt opening release (SOR). Allows the circuit breaker to be opened by means of a nonpermanent electrical control. Release operation is ensured for voltages between 70% and 110%

Cabled SOR - UVR

of the rated power supply voltage Un, in both alternating and direct current. The SOR is equipped with a built-in limit contact to shut off the power supply in the open position with the relay tripped. A remote controlled emergency opening command can be created by connecting an opening button to the SOR.

Undervoltage release (UVR). Allows the circuit breaker to open when the release is subjected to either a power failure or a voltage drop. Opening is ensured when the voltage is between 70% and 35% of the rated power supply Un. After tripping, the circuit breaker can be closed again if the voltage exceeds 85% of Un. When the undervoltage release is not energized, neither the circuit breaker nor the main contacts can be closed. A remote controlled emergency opening command can be created by connecting an opening button to the UVR.

None of the service releases in the Tmax XT series requires screws for installation. They are extremely easy to fit. Just use slight pressure to snap the release into the appropriate place. All service releases are available in two versions:

cabled (AWG20 cable section - 0.5mm2):

– for fixed/plug-in circuit breakers with 1m long cables; – for withdrawable circuit breakers with fixed part and moving part connector;

not cabled:

– for fixed/plug-in circuit breakers with cables from (1.5 mm

/14 AWG in section).

In circuit breakers:

three-pole: either one SOR or one UVR can be installed in the slot on the left of the operating

lever;

four-pole: two service releases can be installed at the same time by using the third and fourth

poles. If the circuit breaker is the withdrawable type, the connector for the fourth pole must be ordered to be able to install an SOR or UVR in the fourth pole.
