When the relay operates, one or more contacts will operate and energize a trip coil in a Circuit Breaker and trip (open) the Circuit Breaker.
当继电器动作时，一个或多个接触器动作且给断路器的脱扣线圈通电，从而将断路器断开。
If a fault occurs, the fuse ruptures diverting all the fault current through the trip coil, tripping the breaker.
如有故障发生，熔断器会断开，使所有故障电流流经跳闸线圈，将断路器断开。
The protective relay is a sensing device, which senses the fault, determines its location and then send command to the proper circuit breaker by closing its trip coil.
保护继电器是一个传感装置，感官的过错，确定其位置，然后发送命令关闭其旅行线圈到正确的断路器。
