It is rated for 225–400 A and 600 V, with a 200 kAIC short-circuit current rating, and uses knife-blade terminations at both ends for quick insertion and removal. This open-block design belongs to Eaton’s Bussmann series JM modular fuse blocks and is intended for Class J fuses, supporting conductors from 4 AWG to 600 MCM copper or aluminum. The JM60400-1CR variant is a single-pole configuration and is designed for 600 V systems, enabling reliable protection in industrial control panels and power distribution applications, and pairs with Class J fuses to protect feeders and circuits with up to 400 A capacity. As part of the Class J block family, it mounts in standard panel installations and accepts a broad range of supply conductors, simplifying integration in protection schemes. Covers sold separately, this fuse holder block supports modular assembly in compact control panels while delivering high-current protection up to 400 A at 600 V and 200 kAIC.\u003c\/p\u003e\u003c\/div\u003e","brand":"BUSSMANN","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677528555822,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ce001066-6460-432e-acef-ea79ce52220e.jpg?v=1769564164","url":"https:\/\/plgautomation.com\/products\/bussmann-j60400-1cr-fuse-holder-block-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
