Why Choose the ABB OS100GB22N1 100 A 4-Pole BS Switch Fuse?

The ABB OS100GB22N1 is a 100 A, 4-pole, front-operated switch fuse designed for switching, isolation and fuse protection in low-voltage electrical distribution systems. Part of the ABB OS range, this GB-type model uses the British Standard fuse system and accommodates A2-A4 fuse links.

The OS100GB22N1 uses mechanism 22 positioned between the poles and incorporates a non-fused switched neutral with a solid link. This four-pole configuration allows the neutral conductor to be switched together with the fused phase conductors, making the unit suitable for installations requiring simultaneous phase and neutral isolation.

This version is supplied without an operating handle or shaft, allowing suitable operating accessories to be selected separately for the enclosure arrangement. With a 100 A switching current, 690 V AC switching voltage and base-mounted construction, it provides a robust solution for industrial distribution and switchboard applications.

Key Advantages

  • 100 A, 4-pole switch fuse for low-voltage electrical distribution.
  • British Standard design for A2-A4 fuse links.
  • Includes a non-fused switched neutral with solid link.
  • Front-operated design with mechanism positioned between the poles.
  • Rated for switching applications up to 690 V AC.
  • Supplied without handle and shaft for flexible accessory selection.

Key Features

  • ABB OS100 GB-type switch fuse.
  • 100 A rated switching current.
  • 4-pole configuration.
  • 690 V AC switching voltage.
  • A2-A4 mechanical fuse size.
  • Mechanism 22 positioned between the poles.
  • Switched neutral with solid link.
  • Base mounting with lug terminals.
  • Handle and operating shaft not included.

Four-Pole Fused Switching with Switched Neutral

The ABB OS100GB22N1 combines manual switching and isolation with fuse-based circuit protection in a four-pole arrangement. Its non-fused switched neutral uses a solid link, allowing the neutral to be switched alongside the fused phase conductors while maintaining the required neutral connection arrangement.

The front-operated, base-mounted design makes the OS100GB22N1 suitable for integration into switchboards and electrical enclosures. Because the handle and shaft are not included, appropriate ABB operating accessories can be selected to match the enclosure depth and installation requirements.

Typical Applications

  • Industrial low-voltage power distribution.
  • Four-pole electrical isolation systems.
  • Switchboards and distribution panels.
  • British Standard fused distribution circuits.
  • Three-phase systems requiring switched neutral isolation.
  • Industrial machinery and equipment feeders.
