Bussmann KRP-C-2000SP Low-Peak Class L Time-Delay Fuse

Bussmann KRP-C-2000SP Low-Peak Class L Time-Delay Fuse, 2000A

The Bussmann KRP-C-2000SP is part of the Eaton Bussmann Series KRP-C Low-Peak line of current-limiting, time-delay fuses engineered for demanding industrial and commercial power distribution systems. Rated 2000A with a dual voltage rating of 600Vac and 300Vdc, this Class L fuse delivers a high interrupt rating of 300 kAIC at 600Vac and 100 kAIC at Vdc, making it well suited for protecting equipment and conductors in systems with high available fault current. The fuse features bolted blade end x bolted blade end terminations for secure, low-resistance connections in large-amperage circuits. As a current-limiting, time-delay device, the KRP-C-2000SP is engineered to 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 fuse is commonly specified by electrical contractors, panel builders, and engineers for service entrance, feeder, and switchgear protection where high interrupt capacity and dependable performance are required.

Key Features

• Amperage Rating: 2000A rating supports high-capacity overcurrent protection for large feeder and service entrance circuits.
• Dual Voltage Rating: 600Vac and 300Vdc rating allows the fuse 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: 300 kAIC at 600Vac and 100 kAIC 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.
• Low-Peak Series Design: Part of the Eaton Bussmann Low-Peak family of current-limiting fuses engineered for demanding industrial applications.
