Introduction

Bussmann's snap-in H(K), J, and R class knife-blade fuse holders offer enhanced flexibility and electrical safety. As the only company with a complete portfolio of circuit protection solutions to meet diverse application needs, Eaton and Bussmann deliver unmatched leadership in circuit protection. Bussmann knife-blade fuse holders feature modular design, high ratings, ease of use, safety, and rapid shipping. The modular design allows assembly of the required number of poles at the point of use, with factory-assembled two-pole and three-pole configurations also available. All fuse holders meet UL creepage and clearance requirements for industrial control circuits, while 200 to 600A fuse holders comply with the more stringent UL industrial power distribution standards. An optional high-visibility, finger-safe transparent cover includes test probe access holes for routine maintenance. Bussmann offers optional IP20 finger-safe covers across the entire knife-blade fuse holder product line. Built-in lockout/tagout functionality enhances safety, blown fuse indication options on fuse covers aid troubleshooting, and standard phase barriers between poles improve safety. Rapid shipping services include standard service (90% of orders shipped within 24 hours) and emergency service ("next available flight" express delivery available 24 hours a day, 365 days a year).
