Coming back to my earlier point, if you oversize the C-curve MCB to compensate for its lower tripping current, you end up running a huge risk of not protecting the motor at all under overloads. 4. is best for me? To support a more informed basis for considering the products available in each . category today, this paper provides a technical review of single and double break MCCB design principles and the potential impact on device performance. Component breakdown of single and double break MCCBs. Though individual MCCB designs vary, all Miniature Circuit Breaker 10kA Miniature Circuit Breaker. Cat ref. Description. P.U. Trade Price*. NBN106N. MCB 1P 10kA B-6A 1M. 1 prt. 3 indicates the energy level of the mcb: The MCB can be used up to 5.5 KW of Power. 220/415V: It is the maximum allowable voltage limit. 50 Hz: The Frequency indicates AC operation. In our case, if the input current through the MCB is reached more than 20 A means, the bimetallic arrangement trips the MCB. It is called an overload trip. There are a lot of the DIN rail breakers that have both an AC and DC spec, with only the AC spec printed on the breaker case. You have to find the spec sheet for the breaker in question for the answer. I couldn't find a spec sheet for the CHNT CB-125A on line, so that makes it kind of difficult. .
