Circuit breaker timing test standard

WebThe main function of a circuit breaker is to open under a fault condition. The speed of the contact opening is critical to minimizing the damage to the breaker and the equipment it feeds. The time between the impulse to actuate the trip coil and the actual opening of the circuit breaker indicates how quickly the circuit breaker operates.
