Is an unstable power supply giving you trouble? Take a load off using this MCB from Siemens. The device safely cuts the flow of electricity in the event of overload or a short circuit, so there's less chance of power faults causing damage to your equipment. This also protects you from the risk of electric shocks. For snappy installation, simply clip the unit onto a DIN rail. A miniature breaker like this one is just what you need to protect low-voltage industrial and commercial lighting systems. It's also ideal to use with equipment that experiences high in-rush current, such as a motor.

• Halogen-free, meaning it gives off no harmful toxic fumes if there's a fire
• Screw terminals hold wires firmly, so there's minimal need for retightening
• Compatible with extreme locations, thanks to its broad operating temperature range between -25°C and +55°C
• Compact dimensions of 90 (H) x 18 (W) x 76mm (D) maximises board-packing efficiency

The unit has type-C tripping characteristics, so it safely trips when it receives 5 to 10 times its rated current of 3A. This means it safeguards against power surges.
