This single‑element fuse uses a bolt‑on body with bolted blade ends, and is intended for use with Bussmann JM600 fuse blocks, making it suitable for solid panel and busbar mounting in industrial electrical systems. It features a non‑indicating visual indicator and an interrupt rating of 200 kA RMS at 600 VAC, ensuring rapid short‑circuit protection while limiting arc energy. The physical footprint is about 2 in by 8 in, reflecting a compact yet robust cartridge built for demanding environments. Electrical and safety certifications are solid: UL Listed to 248‑8 (Guide JDDZ, File E4273) and CSA certified to 248.8 (Class 1422‑02, File 53787), underscoring its suitability for compliant, code‑driven installations. Commonly referenced as JKS‑450 or Limitron JKS‑450, this fuse delivers fast action for feeders, motor circuits, and distribution panels in 600 V systems where rapid current interruption is essential. Its data sheet confirms a 450 A ampere rating, a 600 V voltage rating, a 200 kA interrupt rating, and a bolted blade end connection, with a single fusible element and current‑limiting performance that helps coordinate protection with compatible fuse blocks.\u003c\/bussmann\u003e\u003c\/div\u003e","brand":"Bussmann","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677525475630,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5127f958-fdd3-49cb-8847-2c812379eee1.jpg?v=1769564117","url":"https:\/\/plgautomation.com\/products\/bussmann-jks450-fuse","provider":"PLG Automation ","version":"1.0","type":"link"}
