Bussmann series KRP-C 601 to 2000A Class L fuse data sheet No. 1008
High-current protection with precise selectivity is provided by the KRP-C-1500SP, rated at 1500 A for demanding power distribution and motor control panels. By using a single, widely supported Class L fuse across feeders and main circuits, OEMs can reduce bill-of-materials while improving coordination between protection devices. This streamlines procurement, minimizes stocking variations, and yields more predictable fault-clearing behavior in harsh industrial environments where space is at a premium. Time-delay, current-limiting performance helps manage inrush without triggering nuisance trips. The KRP-C-1500SP remains closed during startup transients and clears faults quickly, with a measured response of 4 seconds at 500% overload. This balance translates to longer motor life, fewer unplanned outages, and lower maintenance costs in process lines and machine centers. With an interrupt rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, the fuse delivers robust fault protection in both AC and DC circuits. This capacity is critical for switchgear, MCCs, and power distribution units that experience variable fault energies, ensuring safe disconnection and protecting downstream electronics, drives, and relays from damaging energy surges. Installation and compatibility are straightforward: bolted blade end x bolted blade end connections, 10.75 in length, and a compact 3.03 by 3.03 in footprint weighing 5.72 lb. Standard packaging simplifies logistics, while the non-indicating indicator keeps control panels clean. These physical attributes support faster field installs, easier retrofits, and reliable performance in tight enclosures. RoHS-compliant and CE-marked, the KRP-C-1500SP aligns with global regulatory requirements. It integrates seamlessly with Eaton Bussmann’s full-line catalog and is supported by the Bussmann data sheet No. 1008 for KRP-C 601–2000 A Class L fuses, enabling quick verification and procurement across international projects.

FAQs
Because the KRP-C-1500SP uses bolted blade end connections, ensure mating interfaces match the enclosure and that torque specifications are followed for secure mounting. Account for the fuse length of 10.75 in and cross-section of 3.03 by 3.03 in, with an approximate weight of 5.72 lb. Provide adequate clearance for heat dissipation and easy access for maintenance.
The fuse provides time-delay operation to tolerate motor start-up surges while protecting downstream equipment. It offers current-limiting protection with a 1500 A rating and 300 kAIC interrupt rating at 600 Vac, enabling fast fault clearing without compromising motor life. This balance reduces nuisance trips and supports reliable panel operation during machine starts.
Ideal for switchgear, motor-control centers (MCCs), and heavy-distribution panels in manufacturing and process industries, the KRP-C-1500SP handles high fault energies and routine motor starting. Its Class L time-delay design supports controlled inrush management, while maintaining protection coordination with upstream devices in demanding environments.
The KRP-C-1500SP is RoHS compliant and CE marked, aligning with global regulatory requirements. It is documented within Eaton Bussmann’s full-line catalog and data sheets (No. 1008 for KRP-C 601–2000 A Class L fuses), enabling quick compliance verification and consistent sourcing across international projects.
Using the KRP-C-1500SP can reduce downtime through reliable protection and fewer nuisance trips, while simplifying stocking with a single, widely supported part across feeders and main circuits. The standardized, bolted-blade design speeds installation and retrofit projects, lowering labor costs and improving overall lifecycle cost in complex energy systems.
