Operating instructions

The load switch closing operation

Install and fix the mechanism on the body, using a special operating handle, inserted into the upper mechanism (closing operation axle), rotates clockwise around 90 ", the main circuit is closed under the action of the spring force of the mechanism,or the motor operated is energized by pressing the closing button to drive the mechanism to complete the switch closing operation.

The load switch opening operation

Use a special operating handle, which is inserted into the upper part of the mechanism (closing operation axle),rotates counterclockwise for about 90". The main circuit is opened under the action of the spring force of the mechanism,or the motor operated is energized by pressing the opening button to drive the mechanism to complete the switchopening operation.

The grounding closing gate operation of load switch

The operating handle is inserted into the grounding operation axle(lower part) rotates clockwise around 90° ,and the grounding circuit is closed under the action of spring force of the mechanism.

The grounding opening gate operation of load switch

Turn the operating handle counterclockwise by about 90° , and the grounding circuit is opened by the body under the action of the spring force of the mechanism.

Notes on using environmental conditions

The ambient air temperature does not exceed 40*0, and measured within 24 hours, minimum air temperature -40*0.

Elevation W2000 m, shatter crack degree w8 degrees.

In places where there is frequent and severe vibration, there are places where water vapor, gas, chemical corrosionsediment, salt spray, dust and dirt, which are obviously affecting the performance of the mechanism, and explosion and fire hazard environments are not suitable for use.
