Bussmann series KTS-R 600 V Class RK1 fuse data sheet no. 1044
The KTS-R-150 fuse combines high current capability with rapid response to fault conditions, delivering a significant reduction in fault energy and downstream damage. This translates to lower repair costs, fewer unplanned outages, and improved panel uptime for critical processes in automation and electrical protection systems. Application-wise, it serves well in motor control centers and distribution panels where 150 A protection and a 200 kAIC interrupt rating at 600 V are essential, ensuring reliable coordination with upstream devices. Its fast-acting, current-limiting design minimizes conductor overheating during faults, improving safety margins and equipment longevity in industrial environments. The blade-end x blade-end connection, along with 70/30 brass end caps and a melamine glass tube, provides durable contact and resistance to arcing, facilitating straightforward integration into standard fuse holders. With a non-indicating style, maintenance is simplified and visual wear is reduced, cutting lifecycle costs. The fuse’s dimensions—9.63 in length, 1.5 in width, and 1.5 in height—and a weight of 1.23 lb support easy handling, stocking, and replacement in busy equipment rooms.

FAQs
For installation, the KTS-R-150 uses blade end x blade end connections and fits in standard fuse holders designed for RK1 class fuses. Its dimensions are 9.63 in long with a 1.5 in width and height, and it weighs 1.23 lb. Ensure adequate clearance for heat dissipation and proper alignment with upstream protective devices to achieve coordinated protection in 600 V systems.
The fuse is rated for 150 A with a 200 kAIC interrupt rating at 600 Vac, and a 600 V voltage rating. This combination supports reliable motor protection by promptly interrupting fault currents, limiting arc energy, and improving protection coordination with upstream breakers or fuses in motor control centers and 600 V distribution panels.
Yes. The KTS-R-150 employs blade end x blade end connections designed for common fuse holders. Its Class RK1 designation aligns with standard protective devices, and its 9.63 in length facilitates integration into many control panel configurations. The 70/30 brass end caps further enhance contact reliability, reducing contact resistance during operation.
Current-limiting capability reduces fault energy and shortens arc duration, protecting conductors and insulation from excessive stress. This minimizes collateral damage, supports safer maintenance, and lowers repair costs. In 600 V industrial systems, this translates to faster fault isolation and improved overall equipment reliability in automation and electrical protection schemes.
Document CE marking as proof of safety compliance for the KTS-R-150, and note its RK1-class fuse designation for standard protection. For RoHS considerations, refer to Eaton’s RoHS information resources to verify material compliance. The Bussmann data sheet and Eaton catalogs (data sheets no. 1044) provide official specifications to support regulatory audits and procurement approvals.
