Selection & Application Guide
The MTE World reactor (RLW) is an international product that is optimized to support global
IEC and NEC Drive /motor applications and provides a low cost line side alternative to the
present line of MTE “RL” line/ load reactors. RLW’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 selection table
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.
Single phase applications: The RLW like RL reactors may also be sized to protect single
phase drives. Please see MTE application AN0120 for details
Load side applications require use of the reactor output selection tables.
Choose the impedance level:
1.5% Minimum impedance for reduction of low level voltage transients. RLW reactors
may be used as a supplement to already installed reactors.
3% Helps minimize (95%) most drive nuisance tripping and faults caused by over
voltage and input line disturbances. 3% is typical impedance specified by most
drive manufacturers.
5% The MTE recommended value to protect drive components from transient
overvoltage, prevents (99.9%) nuisance trips, and offers limited harmonic
protection to input line power from drive inducted harmonics.
