Keen to find a breaking solution to protect your critical circuits? Choose this MCB from Siemens. It shuts down a circuit if too much current is supplied, stopping the flow of electricity to shield people from harm and equipment from damage. As this is a type-C breaker, it promptly cuts the electrical supply if it receives between five and ten times its rated load of 100A. This makes it handy when you're working with inductive loads with high switching surges, so it's a practical pick for use with your motors and fluorescent lights.

• Straightforward single-pole device for breaking a single circuit
• Easy-to-use screw terminals achieve a robust electrical connection
• Handles solid or stranded conductors from 25 to 50mm² or 3 to 1AWG, so it's widely compatible with commonly used cabling
• Mechanical service life of 10,000 cycles means it's a long-lasting option
• IP20 rating indicates it's touch-proof to boost workplace safety

Thanks to its handy snap-on mounting style, it's easy to install this MCB on a 35mm DIN rail without any tools.
