It uses a thermal‑magnetic trip with long‑time and instantaneous trip functions and ships with a non‑interchangeable trip unit, providing reliable overcurrent protection for feeders and motor circuits. The unit is specified for a 40 °C ambient environment and delivers a 30 kA short‑circuit rating at 480 V, making it suitable for moderate‑voltage protection duties in industrial and commercial panels. Because it occupies Challenger's SJK family, the 3‑pole configuration and 600 V rating align with common 3P protection schemes; as always, verify panel compatibility, mounting hardware, and torque requirements before replacement.\u003c\/p\u003e\u003c\/div\u003e","brand":"Challenger","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677930094894,"sku":null,"price":226.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_791c90fd-4cf2-450e-978a-88ffe98cad27.jpg?v=1769569620","url":"https:\/\/plgautomation.com\/products\/challenger-sjk-3-c-600-molded-case-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
