The DH2-125 isolation switch is suitable for ac 50Hz, rated current 125A and below, rated voltage 400V in distribution and control circuits. It is mainly used as a switch in terminal combination appliances, but also for controlling motors, low-power appliances and lighting. It is widely used in industrial and mining enterprises, high-rise buildings, commercial and household places.

Conformity with standard: GB 14048.3, IEC 60947-3.

Structural characteristics of

NDHL-125 isolation switch consists of housing, operating mechanism, contact system.The operating mechanism is firmly connected with the contact system, and there is a clear indication of the contact position. "ON" means the closed position of the contact, and "OFF" means the disconnected position of the contact.
