MTE Corp’s RL Line/Load Reactors – Product Spotlight

MTE Corporation’s RL Series Line/Load Reactors are best-in-class power quality units with a long history of proven performance. They excel at absorbing power line disturbances than can damage or shut down variable frequency drives and other sensitive equipment.

RL reactors work on both the line side and load side, providing a simple solution that reduces nuisance tripping, reduces harmonic distortion and minimizes long lead effects.

RL Line/Load Reactors are designed for power filtering and work with any four- or six-pulse rectifier or power conversion unit. Harmonic compensation and protection assure optimum performance in the presence of harmonics, and substantial overcurrent ratings virtually eliminate breakdowns in the field.

Reactors in the series serve anywhere from 1 to 1,500 A within an input voltage range from 208 to 690 V. The continuous service factor for reactors rated up to 750 A is 150 percent of the rated current, and 125 percent for reactors above 750 A. RL Reactors can sustain service under overload for 30 minutes (200 percent rated voltage), or for 1 minute (300 percent rated voltage).

Three impedance levels are supported: 1.5, 3 and 5 percent. The inductance curve for RL reactors is specified as follows: 100 percent at 100 percent current, 100 percent at 150 percent current, and 50 percent at 350 percent current.

With these robust ratings and built-in protective features, RL reactors are suitable for fast-switching systems like IGBT applications. They also boast a high saturation current rating to handle surge current, and protect motors from high peak voltages and fast rise times.

Finally, multiple cabinet designs are available to satisfy NEMA 1/2 and 3R specifications.
