1.Function: The LBS is designed to make, break, and carry currents. It is an essential part of the circuit that allows for safe switching during normal operation.

2.Use Case: LBS is commonly employed for on-load switching. It enables the opening and closing of circuits while current is flowing.

3.Safety Considerations: LBS does not provide isolation. Therefore, it is not suitable for tasks that require complete disconnection from the power source.

4.Applications: LBS finds applications in various scenarios, such as load shedding, sectionalizing, and maintenance operations.

5.Isolation Function: LBS does not fulfill the isolation function; it is not intended for safety isolation.
