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.
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.
