RLN/RLS Series Renewable Fuses 250/600 VAC I Renewable I 1-600 Amperes
This handbook describes the RLN (250 V) and RLS (600 V) Class H renewable fuses, covering voltage ratings, interrupting capacity, ampere range, and UL/CSA approvals. It also lists part numbers, fuse link options, and recommended fuse blocks for each series.
Additional sections address cost considerations, safety cautions, and dimensional references, and recommend modern replacement fuses such as POWR-PRO IDSR and FLNR series for improved safety and reliability.
| Voltage rating (AC) | 250 V (RLN) / 600 V (RLS) |
|---|---|
| Interrupting rating (AC) | 10,000 A rms symmetrical |
| Ampere range | 1 – 600 A |
| UL approval | Class H fuses per UL 248 |
| CSA approval | Spec No. 59.1 |
| Fuse link types | LKN (250 V) or LKS (600 V) |
| Recommended fuse blocks | LH250 series for RLN, LH600 series for RLS |

The fuses are rated for a 10,000 A rms symmetrical interrupting capacity.
RLN fuses are rated for 250 V AC, while RLS fuses are rated for 600 V AC.
Use POWR‑PRO IDSR series Indicator fuses for 250‑600 V circuits and FLNR series fuses for 250 V and below circuits.
