Eaton's 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.

• The perfect solution for installing as a safety measure
• Used as an emergency switching off/emergency stop device
• The basic functions: used as a main switch, maintenance switch or manual override switch
• Thermoplastic, high impact surface mounting enclosure with an IP65 rating - this means that the enclosure part of the isolator has ingress protection against dust and is also protected against low-pressure jets of water that comes from all directions
• Built-in earth commoning block
• Lockable in the 0/OFF position, with up to three padlocks
• Totally insulated
• Red rotary handle and yellow locking ring, providing an aesthetically pleasing finish

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.

Switch power/capacity refers to AC23A use at 380-440V

This isolator switch from Eaton is designed to safely isolate a circuit while it's being used or maintained. Also known as a switch disconnector, it breaks current flow to the circuit through the rotation of a lockable rotary handle. It can also serve as an emergency stop function as it's designed to be lockable in the off position. As it's fully insulated, it protects you and your equipment against electrical short circuits. You'll commonly find this switch used for the maintenance and repair of circuit breakers and transformers.

• Impact and corrosion-resistant thermoplastic enclosure for use in harsh environments
• Broad operating temperature range of -25°C to +50°C for use in a range of demanding applications
• IP (ingress protection) 65 rating for protection against dust and low-pressure water jets
• Surface-mounted for ease of access

A non-fused switch disconnector like this one doesn't use a fuse to break a circuit. It uses a rotary to disconnect or isolate a circuit, which eliminates the need to change the fuse in the event of breakage.
