What is a Load switch?

A load break switch is a device that opens and closes an electrical circuit through which a load current is flowing. Generally, it refers to products that switch high-voltage AC load currents. Furthermore, it often refers to LBS (Load Break Switch) among them. Disconnectors, circuit breakers, and load switches are devices that switch circuits on high-voltage lines. A disconnector is a device that cannot switch load current and is used for safety management during maintenance work. A circuit breaker is a device that can interrupt not only the load current but also the fault current at the time of a short circuit, and is widely used in the main power receiving equipment and power distribution. A load break switch can switch the load current, but it cannot interrupt the short circuit fault current. Generally, it is used together with a current-limiting fuse to protect the upper circuit from accidental current.

Application of Load switch

✅Power Supply Systems
Load break switches are used in power supply systems to disconnect circuits when there is an overload or short circuit. When an abnormal current is detected, the load break switch operates to cut off the circuit, protecting electrical equipment and preventing risks such as fires and damage to the system.
✅Power Plants
In power plants, load break switches are used for protecting circuits connected to generators and transformers. When an overload or failure occurs, the load break switch immediately disconnects the circuit, preventing damage to the equipment and ensuring stable power supply.
✅Industrial Machinery
In industrial machinery, load break switches are used to protect against overcurrent or abnormal current situations. For example, in a factory's production line, the switch helps protect machinery and equipment from overload, minimizing downtime and preventing damage to production systems.
✅Electric Vehicle Charging Systems
Load break switches are used in electric vehicle (EV) charging systems to prevent overcurrent or overload situations. If an abnormal condition occurs during charging, the switch disconnects the circuit to ensure safety during the charging process.
