Earth Switch Interlock
Earth Switch Interlock
(OP)
Can somebody provide me information whether an earth switch used in switchgears can be fitted with a solenoid wired to external circuit breaker auxiliary contact wherein, the earth switch is blocked (by the shaft driven by the solenoid) when the external circuit breaker is closed.
Is this possible and available in the market? Can anyone provide me links if available?

RE: Earth Switch Interlock
Its a long time since I worked in switchgear however from memory all switchgear units have interlocks between the eartning switches and main breaker, it maybe possible to get an interlock driven by a solenoid it would still have to meet certain requirements ie:- failsafe, if the power to the solenoid driving the interlock failed you should still not be able close the earthswitch with the main breaker in service.
You could try Whipp & Bourne Switchgear, GEC Switchgear or ABB Switchgear they maybe able to help further.
