Mersen RLS Series Class H Renewable Fuse Link, 600V Fast-Acting

Mersen RLS Series Class H Renewable Fuse Links, 600V Fast-Acting

The Mersen RLS Series is a die-cut zinc renewable fuse link family designed to re-link Mersen RFS Class H fuse holders instead of requiring full fuse replacement. This family covers Motor FLA ratings from 5A up to 110A, giving maintenance teams a single, cost-effective source for restoring overcurrent protection across a wide span of branch-circuit and motor-circuit loads. Rated 600V AC for 50/60 Hz systems with a Fast-Acting speed/characteristic, the RLS links are built for AC circuits where available short-circuit current does not exceed 10,000 amperes. Because the RLS link is renewable, the fuse holder itself is reused after a fault event, reducing waste and total cost of ownership for facilities that standardize on Class H renewable fuses.

Key Features

• Amperage Range: Available across Motor FLA ratings of 5A, 6A, 10A, 15A, 20A, 25A, 30A, 40A, 50A, 60A, 80A, 100A, and 110A to match a wide range of branch and motor circuit loads.
• Fuse Class: Class H renewable design for general-purpose overcurrent protection.
• Voltage Rating: Rated 600V AC for standard commercial and industrial circuits.
• Frequency: Designed for 50/60 Hz AC systems.
• Speed/Characteristic: Fast-Acting response for applications requiring quick fault clearing.
• Short-Circuit Rating: Suitable for AC circuits where available short-circuit current does not exceed 10,000 amperes.
• Renewable Design: Die-cut zinc construction lets the RFS fuse holder be re-linked and reused instead of discarded after an overcurrent event.
• Packaging: Supplied 20 EA per package for stocking and maintenance use.

Why Mersen?

Mersen's RLS renewable fuse links pair Fast-Acting response with a die-cut zinc construction that keeps RFS Class H fuse holders in service instead of scrapping them after every fault. Spanning Motor FLA ratings from 5A to 110A at 600V AC, 50/60 Hz, and rated for short-circuit currents up to 10,000 amperes, the RLS series gives electrical teams a consistent, code-aware way to maintain overcurrent protection across a wide range of branch and motor circuits.
