A counter indicator for circuit breakers maintaining a running count of the number of times that a circuit breaker has been tripped and providing a visual indication of a tripped condition. The counter indicator employs time delay circuitry so as to allow the circuit breaker to be switched manually for purposes of testing without registering a tripped condition. A two stage binary coded decimal counter visually displays the amount of counts that the breaker has been tripped or alternatively when a switch handle has been placed in an intermediate position. The device is powered by an independent battery source providing a continuous power supply to maintain memory and power to a visual display only upon detection of a tripped circuit.
