DAB7N-40 series DPN MCB
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.
Product Description
● 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.
