What Is The Function Of Load Isolation Switch?

The function of Load isolation switch is to connect and disconnect the normal load current in the system, and provide an obvious disconnection point to ensure safety during maintenance.

Specifically:

Connect and disconnect the load current: The load switch has a simple arc extinguishing device, which can open and close the circuit with load, and can connect and disconnect a certain load current and overload current to ensure the continuity of power supply.

Provide an obvious disconnection point: When the load isolation switch is disconnected, the contacts have an insulation distance that meets the specified requirements and an obvious disconnection mark, creating a safe working environment for maintenance personnel.

In addition, the combination of load switch and current limiting fuse in series can replace the circuit breaker to achieve effective control of the current size in the circuit and provide certain protection for equipment such as motors. However, it should be noted that the load switch is not a component that allows frequent operation, and the protection of the motor is not comprehensive. Therefore, in practical applications, it needs to be used in combination with other protection devices.
