This 1-pole, 120 V circuit breaker protects a single hot leg, making it ideal for lighting, receptacle, and small equipment circuits that require fast, predictable interruption of current when conditions exceed safe levels. By preventing excessive current from flowing through wiring and devices, it reduces fire risk and extends the life of connected equipment.\u003c\/p\u003e \u003ch2\u003eIdeal use cases\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eSingle-circuit protection in industrial panels for 120 V lines\u003c\/li\u003e \u003cli\u003eRetrofits or replacements in maintenance programs where NB111020H matches existing NB111020H units\u003c\/li\u003e \u003cli\u003eLighting and outlet circuits in warehouses, manufacturing floors, and workshops\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eHow it compares to broader protection options\u003c\/h2\u003e\n\u003cp\u003eFor scenarios that require protecting multiple circuits or 240 V systems, larger multi-pole breakers are common. This 1-pole design provides focused protection on a single 120 V line, delivering simplicity, ease of installation, and a compact footprint without extra poles or wiring complexity.\u003c\/p\u003e \u003ch2\u003ePractical installation and safety tips\u003c\/h2\u003e\n\u003cp\u003eInstall according to electrical codes and manufacturer instructions. Verify panel compatibility for 1-pole, 120 V breakers and ensure secure mounting in your distribution panel. If you are unsure about wiring or panel type, consult a licensed electrician. Regularly inspect the breaker for signs of wear or arcing and replace if any damage is observed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Industrial","offers":[{"title":"Default Title","offer_id":46423342645410,"sku":"NB111020H","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/industrial-nb111020h-20a-1-pole-120-v-circuit-breaker-487.webp?v=1789299010","url":"https:\/\/www.ampstate.com\/products\/industrial-nb111020h","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
