China Cheap price Thermal Adjustable circuit breaker - DAM1-250 MCCB Moulded Case Circuit Breaker – DaDa
Thermal-Magnetic Circuit Breakers Thermal protection function:(For protection under over load conditions) Bimetal, which provides thermal protection, consists of combination of two metals with different extension coefficients under heat. When bimetal is heated, it bends towards the metal with less extension. In this way, a notch that assists opening of the breaker mechanism is released to disable the breaker. Bending speed of bimetal is in direct proportion with size of the current passing t... -
