Made to fit easily into standard consumer units and distribution boards, this 2-pole device disconnects both live and neutral poles quickly and safely if current exceeds safe levels. It is ideal for protecting lighting circuits, socket circuits and other standard 230\/400V AC circuits up to 16 amps in homes, offices and light industrial environments.\u003c\/p\u003e\n\u003cp data-start=\"742\" data-end=\"1222\"\u003eConstructed to comply with recognised safety standards, this MCB features a \u003cstrong data-start=\"818\" data-end=\"843\"\u003eB-type tripping curve\u003c\/strong\u003e, meaning it trips rapidly when the current reaches approximately three to five times the rated value. This makes it especially suited for circuits where the load is primarily resistive, such as lighting and small appliances. With a \u003cstrong data-start=\"1076\" data-end=\"1102\"\u003e6 kA breaking capacity\u003c\/strong\u003e, it can safely interrupt fault currents up to 6000 amps, providing dependable protection against short-circuit risks.\u003c\/p\u003e\n\u003cp data-start=\"1224\" data-end=\"1704\"\u003eThe compact, modular design clips onto a \u003cstrong data-start=\"1265\" data-end=\"1283\"\u003e35 mm DIN rail\u003c\/strong\u003e for quick installation and can be connected from the top or bottom, giving flexibility during wiring. The device is made from durable, high-quality insulating materials that deliver consistent performance over time, with \u003cstrong data-start=\"1505\" data-end=\"1524\"\u003eIP20 protection\u003c\/strong\u003e to guard against dust and accidental contact. Rated for reliable operation in ambient temperatures from \u003cstrong data-start=\"1629\" data-end=\"1648\"\u003e-5 °C to +40 °C\u003c\/strong\u003e, it performs well across typical indoor environments.\u003c\/p\u003e\n\u003cp data-start=\"1706\" data-end=\"2176\"\u003eThis NB1‑63 series MCB also offers multiple connection options suitable for cable and busbar systems and supports terminal capacity for cables up to 25 mm². With a mechanical life of up to 20,000 operations and an electrical life of around 4,000 operations, it stands up to ongoing switching without compromise. Whether you are building a new electrical panel or upgrading your consumer unit, the NB1‑63B2P16 delivers trusted circuit protection at a competitive price.\u003c\/p\u003e","brand":"CHINT","offers":[{"title":"Default Title","offer_id":49267017351405,"sku":"NB1-63B2P16","price":11.14,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0758\/4861\/4125\/files\/NB1-63-2P.jpg?v=1768830516","url":"https:\/\/callidustrade.co.uk\/products\/16a-2-pole-b-curve-6ka-mcb-model-nb1-63b2p16","provider":"Callidus Trade B2B","version":"1.0","type":"link"}
