VCB-12 side mounted embedded solid seal switchgear VCB Vacuum Circuit Breaker
Intorduction:
VBR (VS1)- 12 side-mounted vacuum circuit breaker is an indoor high-voltage switchgear for three-phase power system with rated voltage of 12 kV and frequency of 50 Hz. It is used as protection and control electric appliance due to special vacuum circuit breaker. Superiority, especially suitable for frequent operations requiring rated current or multiple short-circuit currents.
The VBR (VS1)-12 type side-mounted vacuum circuit breaker is fixedly mounted and is mainly used for fixed switchgear. The circuit breaker can be used alone or in ring power supply, box type or various non-standard power supply. system.
