Give short circuits the elbow with this MCB from Schneider Electric. It's an essential safety device that breaks your electrical supply in current overload conditions, so there's minimal chance of power faults causing equipment failure and blowouts. It's also just what you need for user safety, as it reduces the risk of electric shocks. A handy trip indicator puts you in the know when there's a problem. You can maximise board packing efficiency, thanks to its compact dimensions of 85 (H) x 18 (W) x 78.5mm (D). As the unit withstands impulse voltages of up to 6kV, it's on hand to safely halt powerful electrical spikes.
