Circuit breaker adjustable tripping functions The below time-current curve reflects one possible setup for a 1200 ampere circuit breaker with a nominal (maximum continuous ampere) rating of 1000 amps. This time-current curve will be the basis for discussing adjustable tripping settings of the circuit breakers. See more Continuous Amps (Ir) varies the level of current the circuit breaker will carry without tripping. Ir is a percentage of the circuit breaker’s nominal rating (In). Continuous amps can … See more Long-time delay causes the breaker to wait a certain amount of time to allow temporary inrush currents, such as those encountered when starting a motor, to pass without tripping. … See more Short-time delay, used in conjunction with short-time pickup, controls the time involved in postponing a short-time pickup trip. This allows better coordination with downstream thermal-magnetic circuit breakers and fuses. … See more Short-time pickup is used for selective tripping.The short-time pickup function determines the amount of current the breaker will carry for a short period of time, allowing … See more WebA circuit breaker that uses current-limiting fuses will not have an interrupting rating but will use the interrupting rating of the fuse. By standard, current-limiting fuses must operate in half a cycle or less, although most fuse OEMs state that their fuses typically operate in a quarter of a cycle.
