Technical Specifications: Rated Current: 40 Amp (Ideal for Cooker/Hob & Power Circuits) Breaking Capacity: 10kA (Professional High-Safety Grade) Tripping Curve: Type B (UK Residential Standard) Width: 18mm (Standard Single Module) Terminal Torque: 2.5N.m (Reinforced Screw Threads) Standard: Fully Compliant with BS EN 60898-1 / BS 7671 Expert FAQ (Addressing Common UK Installation Pain Points) Q: Is this suitable for my lighting circuit? A: No. For lighting, you typically need a 6A or 10A breaker. A 40A breaker is for high-load appliances. Using the wrong amperage can be dangerous; always consult a qualified electrician. Q: Will this fit my existing fuse box? A: It is designed for standard 35mm DIN rails used in 99% of UK consumer units. Its 18mm slimline design means it occupies exactly one "way" or slot in your board. Q: Why choose 10kA over standard 6kA? A: It measures how much fault current the breaker can safely interrupt. 10kA is a higher safety rating typically required for properties near power substations or for those wanting maximum safety redundancy.
