This 1-pole device, about 0.5 inches wide, is designed for plug-in installation in compatible Challenger panels and delivers a 10 kA interrupting capacity at 120 V AC, ensuring reliable disconnection during overcurrent events. As part of the A120 family, it offers a compact form factor suitable for protecting 120 V circuits such as lighting and receptacles, with standard thermal-magnetic trip to interrupt overloads. The unit’s compatibility depends on the panel’s designation for Type-A Challenger breakers, so verify that your specific Challenger panel accepts Type-A units before installation. The model is commonly referenced in catalog listings for Challenger’s A120 series as a 20 A, 120 V, 1-pole option and is used to replace older Challenger installations in panels that list Type-A breakers.\u003c\/p\u003e\u003c\/div\u003e","brand":"CHALLENGER","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677939269934,"sku":null,"price":44.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_039b4c59-7c79-41a3-9f8e-7285e74aac67.jpg?v=1769569754","url":"https:\/\/plgautomation.com\/products\/challenger-a120ln-u-20a-120v-1-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
