RLN/RLS Class H Fuses 250/600 VAC I Renewable I 1 – 600 Amperes is a quality product produced by Littelfuse company. It is traditionally used to provide low-cost protection for general-purpose feeder and branch circuits where available short-circuit currents do not exceed 10,000 amperes.
The RLN/RLS Class H renewable fuses are general‑purpose protection devices used for feeder and branch circuits where short‑circuit currents do not exceed 10,000 A. They are offered in a renewable design that requires link replacement for resetting.
The datasheet lists voltage ratings of 250 V AC for RLN and 600 V AC for RLS, interrupting rating of 10,000 A rms symmetrical, and ampere ranges from 1 A to 600 A. Approvals include UL Listed Class H per UL 248 and CSA Certified per Spec No. 59.1. Recommended replacement fuses are POWR‑PRO® IDSR series for 250‑600 V circuits and FLNR series for ≤250 V circuits.
