描述
The ZMG1-125 miniature isolating switch is suitable for the power distribution and control circuits with an alternating current of 50Hz, a rated current of 125A or less, and a rated voltage of up to 400V. It mainly serves as the main switch in the terminal combination electrical appliance, and can also be used to infrequently control various small-power electrical appliances and lighting. It is widely applied in industrial and mining enterprises, high-rise buildings, commercial places, households and other locations.
Compliance standards: GB/T 14048.3, IEC 60947-3.
