Product Description

12KV Vacuum Type Circuit Breaker / High Voltage Indoor Vcb Long Service

Advantages of vacuum circuit breaker or VCB
Service life of vacuum circuit breaker is much longer than other types of circuit breakers.
There is no chance of fire hazard as oil circuit breaker.
It is much environment friendly than SF6 Circuit breaker.
Besides, the contraction of VCB is much user friendly.
Replacement of vacuum interrupter (VI) is much convenient.
Disadvantages of VCB
The main disadvantage of VCB is that it is not economical at voltages higher than 38 kV.
The cost of the switch becomes excessive at higher voltages. This is due to the fact that at high voltages (more than 38 kV) more than two numbers of the circuit breaker are required to be connected in series.
In addition, the production of VCBs is not economic if it is produced in small quantities.
