A load break switch is a disconnect switch that has been designed to provide making or breaking of specified currents. These switches are used to de-energize or energize a circuit that possesses some limited amount of magnetic or capacitive current, such as transformer exciting current or line charging currentLoad break switches, generally comes with the spring mechanism for switching ON & OFF operations.

Load break switch with spring mechanism are generally provided with Fuse protection.
