Bussmann KTS-R-200 Class RK1 Current-Limiting Fast-Acting Fuse

Bussmann KTS-R-200 Class RK1 Current-Limiting Fast-Acting Fuse, 600V/200A

The Bussmann KTS-R-200 is a Class RK1 current-limiting, fast-acting fuse from the Eaton Bussmann Series, engineered to deliver dependable overcurrent protection in demanding commercial and industrial electrical systems. Rated 600V and 200A, this fuse carries a 200 kAIC interrupt rating at 600 Vac, giving it the short-circuit current interrupting capability required for high fault-current applications. The KTS-R-200 features a blade end x blade end configuration, allowing it to be installed directly into compatible blade-type fuse clips, holders, and disconnect switches. Its melamine glass tube body combined with 70/30 brass end caps provides a rugged, dielectrically sound construction designed to withstand the mechanical and thermal stresses of fault clearing while maintaining a reliable, code-compliant footprint in the panel or switchboard.

Key Features

• Voltage & Current Rating: Rated 600V and 200A for use in low-voltage distribution circuits requiring robust overcurrent protection.
• Interrupt Rating: 200 kAIC at 600 Vac short-circuit current rating provides the interrupting capacity needed for high fault-current environments.
• Fuse Class: Class RK1 current-limiting, fast-acting design clears overcurrent faults quickly, limiting let-through energy and downstream equipment damage.
• Blade End Configuration: Blade end x blade end terminals allow direct installation into compatible blade-type fuse clips, holders, and disconnect switches.
• Tube Construction: Melamine glass tube body delivers mechanical strength and dielectric performance under fault-clearing conditions.
• End Cap Material: 70/30 brass end caps provide dependable electrical contact and long-term corrosion resistance.
