The H221SNK N NN1 designation identifies the model and series, delivering reliable interruption of current on overload or short circuit to protect wiring and connected loads in 1‑phase, 240 V circuits. This MCB is designed for use in electrical panels that support Challenger NN1 breakers, offering compact protection for branch circuits in residential and light commercial installations. The 30 A, 240 V rating specifies the maximum load current and system voltage for which the device is intended, helping to prevent overheating, insulation damage, and fire hazards by tripping when fault conditions exceed the rated threshold.\u003c\/p\u003e\u003c\/div\u003e","brand":"CHALLENGER","offers":[{"title":"New","offer_id":51677931798830,"sku":null,"price":166.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a0708249-0fcb-4259-995b-488ad6df2ee2.jpg?v=1769569647","url":"https:\/\/plgautomation.com\/products\/challenger-h221snk-n-nn1-miniature-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
