Applications

Heavy mining ball mills, crushers, and multi-motor VFD drives in Australia and South America.
Industrial electrochemical rectifiers, arc furnaces auxiliary systems, and large automated manufacturing plants.

Features

Engineered specifically for heavy harmonic spectrums including 5th, 7th, 11th, and 13th harmonics from heavy industrial motor drives.
Low-temperature rise thermal margin prevents thermal runaway under continuous non-linear load operations.
Cast resin solid dielectric encapsulation offers superior flame retardancy (F1 class) and zero toxic gas emissions.
