Vzg7-40.5 Integrated Indoor High Voltage Vacuum Circuit Breaker Vcb

The VZG7-40.5 Integrated Indoor HVAC Vacuum Circuit Breaker, successfully developed by our company, meets performance requirements by Chinese standards GB/T1984 and GB/T1985 and the international standard IEC62271-100. It has such advantages as reliable interlocking, compact structure, intuitive and convenient operation, beautiful appearance, stable performance, frequent operation possibility, and obvious isolator break.
The product is 3-in-1: a circuit breaker, an isolation switch and a grounding switch. It is very suitable for receiving and distributing electric energy in 40.5kV three-phase AC50Hz systems in wind power and photovoltaic fields.
 

Key Features:

Integration; a high-performance HV electrical product which can be used as a vacuum circuit breaker, an isolation switch and a grounding switch; 
Isolation design: The isolation switch and the circuit breaker are respectively arranged on each side of the chassis, and the electrical connection on both sides is realized through the through-wall solid-sealed vacuum interrupter pole; A perfect "five-prevention" interlocking device, with easy and reliable interlocking for the cabinets;
