Systems and methods for tripping open circuit interrupters based on the detection of an arc flash using an accessory arc flash detection module are disclosed. The housing of the arc flash detection module is structured to be installed within the frame of a circuit interrupter. The detection module communicates with light sensors structured to detect light from arc flash events, and includes a controller configured to communicate with an electronic trip unit of the circuit interrupter. In one embodiment, the detection module is configured to alert the electronic trip unit that light indicative of arc flash conditions has been detected such that the electronic trip unit can determine whether or not to initiate a trip after determining the magnitude of current flowing through the circuit interrupter. In another embodiment, the detection module is configured to directly actuate a trip of the circuit interrupter based on the detection of light.
