Why Choose the Mersen H320006 UltraSafe Fuse Holder?

The Mersen H320006, also known by the catalogue reference US272, is a robust two-pole modular fuse holder designed for dependable protection and isolation in industrial electrical systems. Part of the Mersen Modulostar® CMS27 and UltraSafe™ US27 series, it accommodates cylindrical fuse-links measuring 27 × 60 mm.

This fuse holder provides finger-safe protection to IP20, helping reduce accidental contact with live components during normal operation and fuse replacement. Its durable thermoplastic or thermoset construction offers strong mechanical and thermal resistance for use in control panels, motor drives, power conversion equipment and industrial machinery.

Rated for operation at up to 800 V AC or DC with a conventional free-air thermal current of 140 A, the H320006 supports demanding semiconductor protection applications. Its two-pole design, Faston lug connections and DIN rail mounting format enable organised and efficient installation within industrial electrical enclosures.

Key Advantages

  • Robust two-pole modular fuse holder for industrial applications.
  • Compatible with 27 × 60 mm cylindrical fuse-links.
  • 800 V AC and 800 V DC ratings for versatile circuit protection.
  • 140 A conventional thermal current rating.
  • Finger-safe IP20 protection during operation and fuse replacement.
  • Convenient DIN rail mounting for industrial control panels.

Key Features

  • Mersen UltraSafe™ US27 modular fuse holder series.
  • Two-pole configuration.
  • 27 × 60 mm fuse-link compatibility.
