After breaking several short-circuit faults, it can still be guaranteed to have normal operation. This 2-pole GE(R) circuit breaker is 40 A rated and can support up to 120 V or 240 V depending on the type of installation. ![]() Type BR breakers are UL approved genuine replacement breakers for load centers made by Westinghouse, Challenger and Bryant. The Square D by Schneider Electric Homeline 40 Amp Two-Pole Circuit Breaker is used for overload and short-circuit protection of your electrical system. The rated operation short-circuit breaking capacity Ics is a kind of breaking index of the circuit breaker. Trips to center position - must turn off then turn back on. This 40 AMP molded case circuit breaker has a 320A-400A short-circuit release and an adjustable overload release from 32A-40A. ![]() After breaking several short-circuit faults, the breaking capacity of the circuit breaker declines. The rated limit short-circuit breaking capacity Icu is the limit parameter of the breaking capacity of the circuit breaker. Breaking capacity: Two indexes of rated limit short-circuit breaking capacity Icu and rated operation short-circuit breaking capacity Ics.A higher overload current leads to a shorter action time of the thermal release. Overload protection current, time curve: it is the inverse-time characteristic curve.Tarping System 40 AMP Manual Reset Circuit Breaker, Push Button Manual Reset Operation. When the circuit is short-circuit or the overload condition is serious, the load current is higher than the tripping current, the main contact terminal of the circuit breaker disconnects. Call (303) 728-9577 with questions on fitment or the application. Tripping current: It is the set value of the action of the current release.Rated current: Rated current of the main contact terminal of the circuit breaker, it is the current value guaranteeing the long-term normal operation of the contact terminal of the contactor.Rated voltage: The rated voltage of the main contact of the circuit breaker, it is the voltage value guaranteeing the long-term normal operation of the contact terminal of the contactor.Can I use a 40 amp fuse in place of a 30 amp It is okay in the sense that it will work, but not okay if you have an over-current just below 40 Amp and your equipment catches on fire. Tips: Main parameters of the circuit breaker A 40-amp breaker could potentially allow unsafe levels of electricity to travel through that circuit and never trip until the flow reaches 40 Amps. ![]() Operating Short-Circuit Breaking Capacity C curve trip characteristic gives you the ability to configure the exact protection scheme you required Typical application for a double pole 40 Amp breaker include an electric range (240V up to 3.75kw) in a home and requiring a wire size of 8-3.Trip-free design, breaker cannot be defeated by holding the handle in the ON position.Excellent breaking capability for its compact size.
