DAB7N-40 series DPN Miniature Circuit breaker(MCB)
Introduction
| DAB7N-40 Series miniature circuit breaker adopts double-break point of 1P+N,the two poles are insulated and isolated from each other,under synchronous operation,N-pole always will make first and break later, which guarantees electric arc breaking capacity of protected pole, also ensures safety of controlled circuits and electric equipment. |
