BUSSMANN KRP-CL-300 Class L High Interrupting Fuse

The BUSSMANN KRP-CL-300 is a 300 A, 600 VAC Class L time-delay fuse from Bussmann (Eaton) engineered for high‑interrupting, current‑limiting protection of large electrical circuits. This dual‑element fuse carries a 200 kA RMS interrupt rating at 600 VAC and 100 kA at 300 V DC, and it uses a bolt‑on body style for secure installation in compatible blocks. It is designed for non‑rejection fuse blocks and is listed as compatible with fuse block series 51215 and 51235, with RoHS compliant construction. The device measures 8-5/8 inches in length and 2-1/2 inches in diameter, and it supports a 300 A rating within the KRP‑CL family, with cross references to KLPC, A4BQ, and A4BY. This fuse is part of the Bussmann Class L offering, intended for protection of large branch circuits where a time‑delay, dual‑element solution is appropriate.
