Arc flash accessory module

Systems and methods are disclosed for tripping off a circuit breaker based on detecting an arc flash using an accessory arc flash detection module. A housing of the arc flash detection module is configured to be mounted within a frame of a circuit breaker. The detection module is in communication with a light sensor configured to detect light from an arc flash event, and includes a controller configured to communicate with an electronic trip unit of the circuit breaker. In one embodiment, the detection module is configured to alert the electronic trip unit that light indicative of an arc flash condition has been detected such that the electronic trip unit can determine whether to initiate a trip after determining a magnitude of current flowing through the circuit breaker. In another embodiment, the detection module is configured to directly actuate a trip of the circuit breaker based on detecting light. 公开了基于使用附件电弧闪光检测模块检测电弧闪光来跳闸断开电路断路器的系统和方法。该电弧闪光检测模块的壳体被构造成安装在电路断路器的框架内。该检测模块与被构造成检测来自电弧闪光事件的光的光传感器通信，并包括被配置成与
