An isolator or disconnector is a switch used to isolate a section of a circuit from any energised conductors, by presenting a visible break in the circuit. Isolators are not designed to break load currents (unless fitted with optional arc-breaking feature) or to break fault currents. In high-voltage systems, isolators are used in conjunction with circuit breakers -with the isolators opened after a circuit breaker has opened the circuit, and closed before the circuit breaker closes the circuit.
