Eaton 3P Pole Flush Mount Isolator Switch - 63A Maximum Current, 30kW Power Rating, IP65

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, manually disconnecting the power supply to isolated parts of the circuit. This type of non-fused isolator switch will be found isolating circuit breakers, transmission lines, transformers and a multitude of other applications.

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

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 switch or knife-blade disconnect to isolate and de-energise a circuit. Commonly used in industrial automation and control settings.

This Eaton isolator switch can function as a control as well as a safety device. It has a rotary handle that's used to shut off the power flow to electrical circuits during maintenance. Three integral rings let you lock it in place with padlocks in accordance with the Lock Out Tag Out (LOTO) safety protocol. This device can also serve as an emergency switch, and its conspicuous red and yellow handle colours make it clearly visible on the panel. Its power rating makes it suitable for use in heavy-duty industrial applications such as electricity transmission and distribution stations.

• Impact-resistant thermoplastic enclosure to protect internal components and prevent electric shocks
• Multiple functions including main, maintenance and repair switch
• Flush mounting style for space efficiency
• IP65 (ingress protection) rating to withstand dust and low-pressure water jets

It's dangerous to operate an isolator switch when there's current flowing through it. This is because it has no internal designs to handle arcing of the circuit, which could lead to an explosion.
