It is rated for 63 A and offers a 6 kA interrupting capacity, operating up to 400 V AC. The unit uses a B‑type thermo-magnetic release, with an instantaneous magnetic trip in the 3–5 In range to augment thermal protection for typical lighting and general power circuits. With a width of 18 mm per pole, the NB1-63-B2 2P fits compactly in standard distribution boards and is available as part of a broader NB1‑63 lineup that includes 1P, 2P, 3P, and 4P configurations for systems up to 400 V. It conforms to IEC\/EN 60898‑1, making it suitable for residential and light commercial branch circuits that require reliable interruption of faults and overloads. As the 2P version of the NB1-63 series, this model protects two conductors and ensures simultaneous disconnection under fault conditions, aligning with common electrical-safety practices in many regions. \u003c\/p\u003e\u003c\/div\u003e","brand":"CHINT","offers":[{"title":"New","offer_id":51678022435118,"sku":null,"price":189.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a2b3a7ca-e957-4b82-9efb-6758acbf7ed8.jpg?v=1769570756","url":"https:\/\/plgautomation.com\/products\/chint-nb1-b2-2p-nb1-63-b2-miniature-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
