DAB6-125 Miniature circuit Breaker
DAB6-125 is such features as delicate appearance, light weight, excellent and reliable performance, high breaking capacity, rapid tripping and mounted by rail. Its enclosure and com-ponents adopts high fire-retarding and shock-resistance plastic of long durability. It mainly serves for protecting the circuits of AC 50Hz, 230V of single pole, 400V of two poles or three or four poles from overload or short-circuit, and also for unfrequented making and breaking electrical apparatus and lighting circuit.It conforms with the standards of IEC60947-2.
Product Description
● Two types of overload and short circuit protection.
● Independent contact position indicator.
● DIN rail latch with a double fixed position.
● Wide range of operating temperatures from –40 to +50° С.
● Updated wider engagement lever with improved contact area.
● Notches on terminal clamps provide for lowering thermal losses and boosting the mechanical stability of connection.
● Higher switching capacity of 10 kA provides for installing DAB6-125 as incoming circuit breakers.
