Make quick work of protecting your circuit with this MCB from Eaton. As soon as electrical issues pop up, it has two ways to instantly deal with them thanks to its thermal-magnetic mechanism. The thermal trip unit responds to an increase in temperature, while the magnetic element reacts to a hike in current. As this device breaks loads of up to 10kA, it shuts down large surge currents without a hitch. Support for AC and DC voltages makes it a flexible fit for industrial supplies. Due to the front-mounted toggles that control the live and neutral connections, resetting your system is done with the flick of a switch. You'll find MCBs like this one protecting systems in packing plants and data centres.

• Snaps onto a DIN rail for easy mounting
• Compact dimensions of 36 (W) x 75.5 (H) x 80mm (D) mean it slots easily into a crowded cabinet
• Light 200g weight doesn't add strain to your setup

An MCB's tripping characteristic indicates how much overcurrent causes the unit to break the attached circuit. This device has a type-C curve, meaning it trips when it receives five to ten times its maximum rated load of 3A.
