GL47-125 Miniature Circuit Breaker
Short Description:
GL47-125 is such features as delicate appearance, light weight, excellent andreliable performance, high breaking capacity, rapid tripping and mounted byrail. Its enclosure and components adopts high fire-retarding andshock-resistance plastic of long durability. It mainly servesfor protecting thecircuits of AC 50Hz, 230V of single pole, 400V of two poles or three or four polesfrom overload or short-circuit, and also for unfrequent making and breakingelectrical apparatus and lighting circuit.It conforms with the standards ofIEC60947-2.
