NH40S Changeover Switch
1.1 Application
Mainly used in the distributing and motor circuit which has high short-circuit current,and acted as main switch or master switch
infrequently operated by hand, it is particularly suitable in the relative high class with drawable low voltage complete equipment.
They provide safety isolation and protection against overcurrent for any low voltage electrical circuit.
1.2 Standard: IEC/EN 60947-3.
1.3 General characteristic
Full-enclosed structure
Unique rolling insert type contact system.
NH40SZ Automatic Changeover Switch
NH40SZ automatic changeover switch disconnectorintegrates electrical and mechanical interlocking systemsto guarantee safe transfer operation.
