General Safety Instructions
WARNING
High Voltage! Only a qualified electrician can carry out the electrical
installation of this filter.
High voltage is used in the operation of line/load reactors. Use extreme
caution to avoid contact with high voltage when operating, installing or
repairing line/load reactors.
Injury or death may result if safety
precautions are not observed.
Line/load reactors are used in conjunction with inverters, or other electrical
equipment that may feedback lethal voltages. Follow the safety instructions
in the equipment used with the reactor in addition to the safety instructions
in this manual.
WARNING
The opening of the branch circuit protective device may be an indication
that a fault current has been interrupted. To reduce the risk of fire or
electrical shock, line/load reactors should be examined and replaced if
damaged.
An upstream disconnect/protection device must be used as required by the
National Electrical Code (NEC) or governing authority.
Even if the upstream disconnect/protection device is open, the drive
downstream of the line/load reactor may feedback high voltage to the
reactor. The drive safety instructions must be followed. Injury or death
may result if safety precautions are not observed.
Line/load reactors must be grounded with a grounding conductor
connected to all grounding terminals. Open panel reactors must have a
2”x2” area cleaned of paint and varnish on the lower mounting bracket.
Only spare parts obtained from MTE Corporation or an authorized MTE
distributor can be used.
Caution
Loose or improperly secured connections may damage or degrade reactor
performance. Visually inspect and secure all electrical connections before
power is applied to the filter.
The user of this reactor must assure that the input voltage and frequency
is correct for the reactor rating and that the voltage applied falls within the
rated operating tolerance envelop specified for the reactor. For severe
power line applications where the power feed is likely to experience surges
and transients that exceed the input voltage rating, it is recommended that
a TVSS (Transient Voltage Surge Suppression) or SPD (Surge Protection
Device) be deployed ahead of the reactor to reduce the possibility of
exceeding the reactor’s rated voltage. Consult with TVSS or SPD
manufacturer to determine the correct protection requirements for your
power line conditions.

Receipt & Repair Statement
Upon Receipt of this Filter:
RL Line/Load Reactors have been subjected to demanding factory tests before shipment.
Carefully inspect the shipping container for damage that may have occurred in transit. Then
unpack the reactor and carefully inspect for any signs of damage. Save the shipping container for
future transport of the reactor.
In the event of damage, please contact and file a claim with the freight carrier involved
immediately.
If the equipment is not going to be put into service upon receipt, cover and store the reactor in a
clean, dry location. After storage, ensure that the equipment is dry and that no condensation or
dirt has accumulated on the reactor before applying power.

Enclosures
MTE enclosures are designed to provide a degree of protection for electrical components and
prevent incidental personnel contact with the enclosed equipment. Depending on the enclosure
selected, these enclosures meet the requirements of NEMA 1/2 or 3R.
An approximate cross reference guide between NEMA, UL, CSA and IEC enclosure follows.
Type 1 NEMA / IEC IP20 Enclosure:
Are designed for indoor use and will provide protection against contact with the enclosed
equipment.
Type 2 NEMA / IEC IP20 Enclosure:
Are designed for indoor use and will provide protection against contact with the enclosed
equipment and provide a degree of protection against limited amounts of falling water and
dirt.
Type 3R NEMA / IEC IP23 Enclosure:
Are designed for outdoor use primarily to provide protection against contact with the
enclosed equipment and provide a degree of protection against falling rain sleet and
external ice formation.

Form: RL-TRM-E April 2019 REV. 001 6
Audible Noise
RL Line/Load Reactors offer low noise operation. Core and coil construction, flux density control,
harmonic compensation as well as our epoxy impregnation process assure minimal audible noise
radiation. Although our reactors are typically “quiet”, waveforms vary by drive type and application
and therefore reactor audible noise may vary by application. Noise levels may be affected by
type of motor and motor conductor as well as motor conductor length.
Typical audible noise levels for units selected from our catalog by HP rating are:
• 2 thru 12 amps 55 dBA
• 18 thru 100 amps 65 dBA
• 130 thru 400 amps 70 dBA
• 500 thru 1200 amps 75 dBA
Service Factor
RL Line/Load Reactors are compensated for the additional currents and high frequencies caused
by the presence of harmonics. The reactor fundamental current rating indicates the typical full
load motor current and is also the basis of impedance rating. Standard reactors rated 1 amps
thru 750 amps offer a full 1.5 service factor rating which allows them to carry overload current up
to 150% of their fundamental rating when applied as an input line reactor. Since the nameplate
ratings of motor drives (ASD) varies widely by manufacturer, this helps to assure that the reactor
maximum current rating is compatible with the nameplate current rating on the ASD. The service
factor rating compensates for ASD manufacturer variances in motor drive current ratings and for
harmonic currents. Nominal inductance is assured all the way up to the service factor current
rating.
PWM / IGBT Protection
RL Line/Load Reactors are protected against the high peak voltage and fast rise time voltage
pulses associated with PWM waveforms. The dielectric strength is 4000 volts rms and RL
reactors meet the ratings of an inverter duty motor (NEMA MG-1, part 31). For convenience, they
can be located either at the motor or at the drive.
Harmonic Attenuation
Our unique harmonic compensation assures maximum circuit inductance in the presence of
complex waveforms and can be relied upon to minimize input total harmonic current distortion
(THID). Additionally, it offers superior absorption of transient voltage spikes. Our standard
reactors will typically reduce 6-pulse rectifier input current harmonics to the following levels at full
load operating conditions:
• 3% reactor alone 45% or less THID
• 5% reactor alone 35% or less THID
• 3% AC reactor + 3% DC link choke 33% or less THID
• 5% AC reactor + 3% DC link choke 28% or less THID
(DC link choke inductance is equivalent ac impedance).

4. HOW TO SELECT
Selection Guide
MTE RL Line/Load Reactors are optimized to support global IEC and NEC Drive /motor
applications. RL’s are RMS current rated impedance devices. Selection is based on the choice
of inductance correlated to the application motor full load amps, voltage and frequency and the
number of phases. Use the product selection brochure based on input voltage and NEC FLA
motor selection table for common voltages. For critical impedance selection based on specific
HP or load currents, consult MTE applications engineering.
Choose the impedance level:
3% Reactors rated at 3% are typically sufficient to absorb line spikes and motor current
surges, and help prevent nuisance tripping to the drive and circuit breakers in most
applications. 3% is typically specified by most drive manufacturers.
5% Reactors rated at 5% are best for reducing harmonic current and frequencies. Use
them when you must reduce VFD drive generated harmonics, and to reduce motor
operating temperature.
Single Phase Applications:
RL reactors may also be sized to protect single phase drives. Please see MTE Application
Note: How to Use a 3-Phase Line Reactor for a Single-Phase Application for details.
NOTE: For inverters feeding isolation transformers select a reactor with a current rating
equal to or greater than that of the transformer primary current.
Please verify information below for proper selection:
Line Voltage and Frequency: Input voltage 208V-690V 50/60 Hz (3-phase); 120V-
600V 50/60 Hz (1-phase). See Table 3-1: Performance Specifications (p5) for
specification.
Current Rating: Support for 1 Amp – 1500 Amps.
Performance: See Table 3-1: Performance Specifications (p5) for specification.
Altitude: 3,300 feet above sea level without derating. See Figure 3-1: Altitude Derating
Curve (p7) for derating information.
Enclosure Type: Open Panel, NEMA 1/2 & NEMA 3R, see Enclosures (p4) for
enclosure descriptions.
Temperature: See Table 3-1: Performance Specifications (p5) for operating
temperature information and Figure 3-2: Temperature Derating (p7) for derating
information.
Refer to Article 430 Table 430.91 of the National Electrical code for the selection of the
appropriate enclosure Type Number for your application.
