Circuit breaker power factor
WebPower factor testing for circuit breakers Circuit breakers are designed to interrupt either normal or short-circuit currents. This paper looks at the various different types of circuit … WebCircuit breakers are tested for a short circuit power factorbased on the interrupting rating and type of device. As shownin Table I, MCCBs, and therefore also ICCBs, have shortcircuit test power factors that range from 15% to 20% forinterrupting ratings above 20 kA, while all PCBs are tested for
