Circuit breaker characteristics
WebTripping characteristics describe the operational and tripping behavior of miniature circuit breakers in the event of an overload or short circuit. The tripping curves of the electromagnetic release and the thermal bi-metal release result in an overall tripping curve for overload protection. WebMiniature circuit-breakers are used to protect cables in installations. They should disconnect automatically as soon as the combination of the current rise and duration causes the …
