Want to carry out maintenance on a circuit without shutting off your whole system? This isolator switch from Eaton makes powering down part of the circuit a breeze, letting you work on it safely while the rest of your setup continues as normal. As a triple-pole, single-throw switch, it's suitable for switching the three-phase loads found in commercial and industrial premises such as factories and workshops. The rotary handle is coloured red so you can spot it easily should you need to break the circuit quickly in an emergency.

• Screw terminals let you make secure connections quickly
• Operating temperature range of -25°C to +50°C makes it suitable for use in harsh industrial environments
• IP65 rating means it's dust-tight and stands up to low-pressure water jets
• Can be padlocked to prevent the circuit from being accidentally powered up before maintenance is complete

No, this is a non-fused isolator that uses the rotary switch to disconnect and de-energise the circuit. This means that when you're ready to power up again, you can simply turn the handle with no need to replace any parts.
