Three-phase reactors

Three-phase line or motor reactors for power converters (intended for the attenuation of notches and spikes as well as reduction of harmonics and limitation of inrush currents in power converters and motor drives). There are also types for the protection of capacitor banks in power factor correction equipment with presence of harmonics (to avoid resonance effects, to minimize harmonic currents through the capacitors and to reduce losses, increasing capacitor life. Manufactured with electrical steel with low losses and copper windings. On request we can manufacture reactors with other characteristics, with built-in thermal switch, etc.
