Put the brakes on power spikes with this MCB from Siemens. It's specifically designed to stop current overload and short circuits in low-voltage electrical circuits, so it's widely compatible. Thanks to its high short-circuit breaking capacity of 5kA, the unit safely blocks even powerful electrical jolts. Its straightforward build makes it a cinch to assemble and you can conveniently mount it in any position. A modular design means you can simply add on an appropriate accessory from Siemens' SENTRON range if you want to boost the breaker's functions. You'll find devices like this used in mechanical engineering applications as well as for protecting lighting systems in public buildings.

• Light weight of 296g puts minimal strain on a DIN rail
• Safe to use in public spaces, as it's halogen-free and doesn't emit toxic fumes in the event of a fire
• Reduced maintenance, thanks to reliable screw terminals that hold wires firmly against vibration

Yes. For ease of use, the breaker is compatible with both single and multi-phase circuits.
