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

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

The Bussmann KTS-R Series is a family of Class RK1 current-limiting, fast-acting fuses from the Eaton Bussmann Series, engineered to deliver dependable overcurrent protection in demanding commercial and industrial electrical systems. This family is available in amperage ratings from 200A to 300A, with every option rated 600V and carrying a 200 kAIC interrupt rating at 600 Vac, giving the series the short-circuit current interrupting capability required for high fault-current applications. Each fuse in the KTS-R Series features a blade end x blade end configuration, allowing direct installation into compatible blade-type fuse clips, holders, and disconnect switches. The 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

• Amperage Range: Available in ratings from 200A to 300A to match a range of feeder and distribution circuit requirements.
• Voltage Rating: Rated 600V across the series for use in low-voltage distribution circuits requiring robust overcurrent protection.
• Interrupt Rating: 200 kAIC at 600 Vac short-circuit current rating on every option in the series 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.
