    • A circuit breaker is referenced that has an indicator lamp that identifies a fault condition after power is interrupted to the circuit breaker. This solution uses light emitting diodes (LEDs) to indicate the trip condition. This solution does not require the power to be enabled to the load side of the circuit breaker in order to power the LEDs to display a trip condition. An overload may be detected when the fault current generates sufficient heat in a strip composed of a resistive element or bimetal to cause the bimetal to deflect and/or bend. The mechanical deflection triggers a trip assembly that includes a spring trip lever to a force a moveable contact attached to a moveable conductive blade away from a stationary contact, thereby breaking the circuit.
    • 以断路器为参考,该断路器有一个指示灯,用于识别电源断路后的故障状态。 该解决方案使用发光二极管(LED)指示跳闸情况。 该解决方案不需要将电源启用至断路器的负载侧,以便为LED供电以显示跳闸状况。 当故障电流在由电阻元件或双金属构成的条带中产生足够的热量以使双金属偏转和/或弯曲时,可以检测到过载。 机械偏转触发一个跳闸组件,该跳闸组件包括一个弹簧释放杆,该弹簧释放杆对可移动触点附着到可移动导电刀片远离静止触点的力进行切断,从而使电路断开。
