Nova reactors are an efficient and effective solution to address both line-side and load-side issues associated with demanding drive applications. They deliver protection for motors and AC drives while minimizing system harmonics.  Benefits include reduced line notching, extended life of switching components and motors, reduced audible motor noise and operating temperature, mitigation of nuisance tripping, and minimization of harmonic distortion.

They are available in standard ratings from 0.5 HP (373 Watts) to 250 HP (745 kilowatts), up to 600 V (690 V with de-rating) and are fully compliant with UL, CSA, CE, IEC, and NEMA standards.
