How To Operate The Load Isolation Switch

The operation steps of Load isolation switch are as follows:

Check before closing the knife switch:

Before closing the load isolating switch, you need to check whether the grounding wire is hung to ensure safety.

Pull open the knife switch and prepare for operation:

Pull open the knife switch, put the circuit breaker handle in the operating position, and then press the "open" button to prepare for the next operation.

Closing operation:

When the circuit breaker is in the closed position, press the "close", "trip" and "stop" buttons. At this time, you can hear the sound of the mechanism action and the corresponding display board indication, indicating that the load isolating switch is closing.

Complete closing:

When the contacts of the circuit breaker are fully closed, release the handle. After all the mechanisms are reset, the power supply operation can be carried out.

Precautions:

During the operation, the operating procedures should be strictly followed to ensure safety.
The load isolating switch is usually used in conjunction with the load switch. When closing the switch, the load switch should be closed first, and then the load isolating switch; when opening the switch, the load switch should be opened first, and then the isolating switch, to avoid phase-to-phase short circuit accidents when the isolating switch is pulled with load.
