Panel Door Mounted Switch Disconnector Eaton's panel mount isolator switch can sometimes be referred to as a switch disconnector, this is because it has been created and designed to safely isolate a circuit whilst it is being used or maintained. This isolator switch breaks or isolates a circuit through the rotation of the rotary handle and locking ring. This type of non-fused isolator switch will be found isolating circuit breakers, transmission lines, transformers and a multitude of other applications. Features & Benefits Padlockable in OFF position, up to 3 padlocks and non-locking versions Ingress protection to IP65 2 and 3 pole versions have built in neutral and earth connections 3 pole switches ('P' type only) accept add-on switched neutral and auxiliary contacts (except 20A switches) – see accessories (RS 219-1439 typical) Rated operating voltage: 690 Vac Switching power quoted for 380 - 440 Vac What is the difference between a fused switch disconnector and a non-fused switch disconnector? Unlike fused switch disconnectors, a non-fuse isolator switch does not use a fuse to break or put a circuit into isolation, they instead use a rotary to disconnect or isolate a circuit.
