Indoor Fixed Type Vacuum Circuit Breaker 12kv 24kv 36kv

الوصف

General:
The vacuum circuit-breakers of type VD4/S are intended for indoor installation in air-insulated switchgear systems. They have a switching capacity capable of handling the loads occurring at start-up and shutdown of equipment and plant units both in normal and in fault state. Vacuum circuit-breakers have particular advantages for use in networks where there is a high switching frequency in the working current range and/or where a certain number of short-circuit breaking operations are expected. Type VD4/S vacuum circuit-breakers are suitable for autoreclosing, and have exceptionally high operating reliability and long life.
