Is the isolator switchable with a circuit breaker?
the disconnector can not be used to turn on or off the current, it is only broken in the case of breaking the circuit breaker, to provide a "clear break point."
Circuit breaker: with overcurrent, short circuit automatic trip function, with degaussing arc extinguishing device, can be used to connect, cut off the high current;
Disconnector: similar to the knife switch, no to prevent overcurrent, short circuit function, no arc device;
