Does the isolator and circuit breaker able to switch to each other?
As the circuit breaker inside the arc suppression mechanism, the circuit breaker in a very short period of time (such as a few hundred seconds) will arc off, so that the circuit breaker safety separation.
When the circuit breaker disconnect the live circuit, the internal contact in the separation of the moment will produce an arc, the higher the voltage or the greater the current, the stronger the arc.
Circuit breaker in normal circumstances, used to close or disconnect the circuit, the failure occurs, under the control of the relay protection device, can automatically disconnect the faulty device or line.
Yes, it just provides a clear breakpoint, and now there are visible breakpoints that have obvious breakpoints.
