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.
Safety switches are effective for disconnecting equipment and circuits from their power source in a swift and safe manner. These tools are utilized in many ways in many industrial and commercial sectors, including being used for safe service entrance, safe disconnect for maintenance and testing, fault protection for motorized equipment, and for emergency stoppage in the event of a complication.
