Bussmann KRP-C Series Class L Current-Limiting Time-Delay Fuse, 600V

Bussmann KRP-C Series Class L Current-Limiting Time-Delay Fuse, 600V

The Bussmann KRP-C Series is a Class L current-limiting, time-delay fuse family engineered for large-scale electrical distribution systems, offered across a wide range from 700A to 4500A to match diverse load protection needs. Every fuse in the series carries a dual voltage rating of 600 Vac/300 Vdc, non-indicating bolted blade end connections, and delivers high interrupt capacity of up to 300 kAIC at 600 Vac and 100 kA at 300 Vdc for demanding fault conditions. Built for large distribution switchboards, machinery disconnects, and power panelboards, the KRP-C Series combines dependable time-delay characteristics with CE marked compliance for professional electrical installations.

Key Features
