Explosion protected mine starter PRVI-М
Starter is intended for remote control switching on/off of three-phase asynchronous motors with short-circuit rotor, which are used in three-phase circuits with alternating current with frequency of 50 Hz with isolated neutral of transformer in coal mines, which are hazardous for gas (methane) and/or coal dust, and also for protection from short circuit current and overload in outgoing power circuits. Starter allows connection of external load with voltage 36 V (local light circuits and automation devices).
