Need a shunt trip to send voltage spikes and transients packing? Choose this surge protector from Eaton. It works by tripping your circuit remotely in case of a surge, which cuts the risk of harm to people or connected bits of kit. You'll find it's a great shout for use in residential or commercial control panels thanks to its maximum operating voltage of 110V AC/60V DC. You can use the unit as a standalone device by mounting it directly onto a standard 35mm DIN rail. Alternatively, add it to an existing auxiliary switch or MCB to provide supplemental protection.

• Red/green indicators let you know know device status at a glance
• IP40 rating means it resists damage from objects or wires larger than 2.5mm
• Works from -5°C to +40°C, so it's a practical pick for tough settings
• Super-slim width of 17.5mm makes it a breeze to fit onto your DIN rail

The unit's twin-purpose terminals open from above and below so you can install both bus duct and cables. This means wiring up the device takes less time.
