    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.
    Advantages
    •Two types of overcurrent protection – thermal and electromagnetic.
    •Independent contact position indicator.
    •DIN rail latch with a double fixed position.
    •Wide range of operating temperatures from –40 to +50°С.
    •Wide engagement lever with improved contact area.
    •Notches on terminal clamps lower thermal losses and boost the mechanical stability of connection.
