To safely shut down a circuit in a jiffy, reach for this high-power isolator switch from Eaton. You can use it to disconnect sections of a circuit carrying currents up to 63A, voltages up to 690V AC and power up to 37kW. This lets you carry out necessary maintenance or identify faults safely. As a 3-pole, single-throw switch, it's suitable for switching either single-phase systems or the 3-phase systems commonly used in industrial settings. This makes it a good bet for factory floors and workshops.

• Red handle makes it easy to spot in an emergency
• Can be padlocked so no one can turn the power back on until you're ready
• Operating temperature range of -25°C to +50°C indicates it's suitable for use in harsh industrial environments
• IP65 rating means it's dust-tight and stands up to low-pressure water sprays
• Screw terminals help you quickly make secure electrical connections

3-phase power uses a 3-wire AC power circuit that has each phase signal set 120 electrical degrees apart. This delivers power more efficiently and consistently than a single-phase system and is commonly used in demanding industrial settings.
