Bussmann series KTU Class L fuse data sheet No. 1010
Class L design delivers fast current-limiting protection for high-current circuits. This reduces arc energy and collateral damage during faults, keeping essential equipment online longer. It’s well suited for drives, feeders, and motor control centers in manufacturing environments. 800 A rating with a 200 kAIC interrupt rating at 600 Vac ensures capable fault handling in heavy-load applications, minimizing equipment damage and downtime. The fuse’s robust construction—silver-plated end bells and a melamine glass tube—supports long service life in challenging environments and simplifies replacement. Bolt mounting and bolted blade end connections enable secure, vibration-resistant installation in control panels and switchgear with minimal field adjustments. CE marking and RoHS compliance help meet EU regulatory expectations while supporting environmental stewardship. The knife blade feature provides predictable opening characteristics for fast isolation of faults in critical power paths.
