Shut down abnormal electrical currents in a flash with this single-pole MCB from Eaton. With a 32A current rating and rated voltage of 48V DC, it handles high inrushes with ease. The unit has type-C characteristics, meaning it trips at five to ten times its rated current with a breaking capacity of 10kA. This makes it a smart choice for high-load applications, from small motors to fluorescent lighting. The breaker's easy to mount, too – just clip it directly onto your DIN rail without reaching for your toolkit.

• Contact position indicator lets you know what's going on at a glance
• Simple removal from the existing busbar thanks to three lock-in positions on the DIN rail clip
• Mechanical lifespan of 20,000 switching cycles means you can count on it for the long haul
• IP20 rating means it's touch-proof to reduce the risk of electric shocks

The unit's compact dimensions of 75 (H) x 17.5 (W) x 80mm (D) make it a good fit for crowded circuit boards.

The unit weighs just 118g, so it won't put extra strain on your system.
