Main parameters and characteristics of circuit breakers

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. WebA Miniature Circuit Breaker (MCB) is a resettable protective device that prevents electrical circuits from catching fire and causing damage to personnel and property. It is a device designed to isolate a circuit during an overcurrent event without using a fusible element.
