It combines a 40-amp rating with a B-type trip curve for predictable protection against overloads and short circuits.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCurrent Rating\u003c\/b\u003e: 40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePole\u003c\/b\u003e: Single-pole (1P) design for one circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTrip Curve\u003c\/b\u003e: B-type curve for fast response to typical fault currents\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTrip Mechanism\u003c\/b\u003e: Thermal-magnetic trip to interrupt fault currents quickly\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eApplication\u003c\/b\u003e: Suitable for residential and light commercial panels needing reliable overcurrent protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWith this MCB, you get reliable, targeted protection that helps prevent overheating, damage, and fire risk from overcurrent events. The B-curve characteristic provides a balanced response—fast enough to clear faults without causing unnecessary trips on normal load fluctuations. The 40A rating makes it appropriate for circuits that require higher protection than a typical lighting circuit but still fit within a standard electrical panel. Its single-pole design simplifies installation, resets quickly after a trip, and integrates with other standard breakers to maintain a clean, safe electrical system.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Fusebox","offers":[{"title":"Default Title","offer_id":53423102394695,"sku":"MT06B401","price":3.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/1156\/5895\/files\/41696e43-0002595_40a-single-pole-b-curve-mcb_415.png?v=1772219135","url":"https:\/\/electricallighting.co.uk\/products\/40a-single-pole-b-curve-mcb-for-residential-and-light-commercial-panels-compact-miniature-circuit-breaker","provider":"Electrical Lighting ","version":"1.0","type":"link"}
