In electrical engineering, a disconnector, disconnect switch or isolator switch is essential for ensuring complete de-energization of an electrical circuit for service or maintenance. Primarily used for circuit breaking, they play a crucial role in electrical distribution and substations where machinery requires power source removal for adjustments or repairs. Disconnectors can be manual or motor-operated and may feature an earthing switch to ground isolated sections, ensuring safety for both equipment and personnel. High-voltage isolation switches allow for the isolation of apparatus such as circuit breakers, transformers, and transmission lines for maintenance. While disconnectors do not control circuits like load switches and circuit breakers, they are vital for safety isolation. As off-load devices, they have very low breaking capacity and are intended to be opened only after current interruption by another control device.
