DAB6-125
DAB6-125 is such features as delicate appearance, light weight, excellent and reliableperformance, 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 servesfor protecting the circuits of AC 50Hz, 230V of single pole, 400V of two poles or three or fourpoles from overload or short-circuit, and also for unfrequent making and breaking electricalapparatus and lighting circuit.It conforms with the standards of IEC60947-2.
