In electrical engineering, a disconnector, disconnect switch, or isolator switch is pivotal in ensuring an electrical circuit is completely de-energized for service or maintenance. These switches are essential for circuit safety, found in distribution and substation settings where machinery must be de-powered for adjustments or repairs. Disconnectors can be manual or motor operated, often paired with an earthing switch to ground the isolated section, safeguarding equipment and personnel. High-voltage isolation switches in substations allow the isolation of apparatus such as circuit breakers, transformers, and transmission lines for maintenance. Disconnectors are not typically used for circuit control but provide critical safety isolation. Unlike load switches and circuit breakers, disconnectors lack mechanisms to suppress electric arcs during high-current interruption. Consequently, they are off-load devices with low breaking capacity, designed to be opened only after current interruption by another control device.
