Product Description:

Ndg1-125 isolation switch (hereinafter referred to as switch) is suitable for ac 50Hz, rated voltage 230V, rated current to 63A resistance circuit, mainly for no load on or off the circuit, as the circuit and power supply to connect or isolate.It is especially suitable for the effective isolation of power supply and the prevention of accidental closing during line maintenance to ensure the safety of maintenance personnel.

Conformity with standard: GB 14048.3, IEC 60947-3

Installation and use

The switch shall be installed vertically, and the terminal of the static contact at the upper end shall be connected with the power supply, so that the moving contact will not be charged when disconnected, so as to ensure personal safety during manual operation.
No load operation is allowed under normal conditions when the switch is closed and disconnected.When disconnected, the ring on the handle of the suit should be fastened on the corresponding hook at the lower end of the switch to prevent accidental closing and ensure the safety of maintenance personnel.

Notes:

The switch should not be repeatedly on and off large overload, should not frequently disconnect the normal working current, and do not push and pull strongly, in order to avoid accidents and shorten the service life.
There is no arc extinguishing chamber in the switch, which is not allowed to break the fault current. If necessary, the user can choose the appropriate fuse combination by himself to make it have a large load and short circuit breaking ability.。
