Bussmann KRP-C Low-Peak Class L Time-Delay Fuse

Bussmann KRP-C Low-Peak Class L Time-Delay Fuse

The Bussmann KRP-C Low-Peak Series is a family of current-limiting, time-delay Class L fuses engineered for demanding industrial and commercial power distribution systems, available in amperage ratings from 1600A to 2000A. Every fuse in this family carries a dual voltage rating of 600Vac and 300Vdc, giving electrical contractors, panel builders, and engineers a dependable option for both AC and DC power distribution applications. Each KRP-C Low-Peak fuse features bolted blade end x bolted blade end terminations for secure, low-resistance connections in large-amperage circuits, and delivers a high interrupt rating — up to 300 kAIC at 600Vac and 100 kAIC at Vdc — making the series well suited for protecting equipment and conductors in systems with high available fault current. As current-limiting, time-delay devices, KRP-C Low-Peak fuses reduce peak let-through current and energy during a short circuit while tolerating momentary overloads and inrush currents typical of large motor, transformer, and feeder circuits. This Low-Peak Class L family is commonly specified for service entrance, feeder, and switchgear protection where high interrupt capacity and dependable performance are required, regardless of which amperage rating in the 1600A-2000A range is selected.

Key Features

• Amperage Range: Available in ratings from 1600A to 2000A to support high-capacity overcurrent protection for large feeder and service entrance circuits.
• Dual Voltage Rating: 600Vac and 300Vdc rating allows every fuse in this family to be applied in both AC and DC power distribution systems.
• Current-Limiting, Time-Delay Operation: Limits peak let-through current and energy during short-circuit events while allowing for momentary overloads and inrush currents from motors and transformers.
• High Interrupt Rating: Up to 300 kAIC at 600Vac and 100 kAIC at Vdc, delivering dependable protection in systems with high available fault current.
• Class L Fuse: Conforms to Class L dimensional and mounting standards for compatibility with Class L fuse blocks, disconnects, and switchgear.
• Bolted Blade End x Bolted Blade End Termination: Secure, low-resistance bolted connections at both ends for reliable, high-amperage electrical continuity across the amperage range.
• Low-Peak Series Design: Part of the Eaton Bussmann Low-Peak family of current-limiting fuses engineered for demanding industrial applications.
