1250A 1600A 630a Vcb Breaker Indoor Side Mounting Three Phase Long Service

DISADVANTAGE OF VACCUM CIRCUIT BREAKER
Requirements of high technology for production of vacuum interrupters.
It needs additional surge suppressors for the interruption of low magnetizing currents in a certain range.
Loss of vacuum due to transit damage or failure makes the entire interrupter useless, and it cannot be repaired on site.
APPLICATIONS OF VACUUM CIRCUIT BREAKER
Because of the short gap and excellent recovery of vacuum circuit breaker, they are very useful as very high speed making switches in many industrial applications.
When the voltage is high and current to be interrupted is low these breakers have definite superiority over the other breakers.
For low fault interrupting capacities the cost is low in comparison to other interrupting devices.
Because of the least requirements of maintenance, these breakers are very suitable for the system which requires voltage from 11 to 33 kV
