VS1 Indoor Electrical Vacuum Circuit Breaker 630Amp Fix Type GB198489
Benefits:
1. Modular spring operating mechanism, easy installation and maintenance
2. New vacuum interrupter of high vacuum and ultra-low resistance,stronger breaking capacity,insulation recover faster, lower contact resistance
3. Item models fully cover the rated current from 630A to 4000A and the rated breaking current from 20kA to 50kA
4. Two installation type: stationary-type, handcart-type
5. With wrong operation prevention interlock,keep risks away
6. Easy control and low maintenance
Application:
Industry factory
Mining enterprise
Power plant
Substation
and etc.
