Disconnect switch

Disconnect switches are used to isolate a component of an electrical system from the power source. Electrical power distribution systems require switching for many reasons, including fault isolation, transfer loads from one source to another, isolation of line segments for purpose of maintenance or new construction, and in some instances for shedding loads. Disconnect switches are frequently used to switch transformer magnetizing current, low level line or cable charging current, and parallel load currents. Disconnect switches are manually operated switches which are used for isolating high-voltage equipment, so that this equipment may be worked on safely. AC disconnect switches are often used for connecting AC current to and disconnecting AC current and operate between on and off conditions by inserting a pullout handle assembly into and removing the pullout handle assembly from a stationary terminal block assembly mounted within the enclosure of the AC disconnect switch.
