1. For isolating the power supply, disconnect the low voltage service equipment from the live equipment with a clearly visible break point between them.
2. The non fusible disconnect switch cooperates with the circuit breaker and performs the switching operation according to the needs of the system operation mode to change the wiring mode of the system operation.
3. Used to turn on or off the small current circuit.
