Why Choose the ABB OS800D22N1 Switch Fuse?
The ABB OS800D22N1 is a heavy-duty 800 A 4-pole DIN switch fuse designed for dependable switching, isolation and fuse protection in demanding low-voltage power distribution systems. Part of the ABB OS fuse switch range, it combines manual circuit isolation with DIN fuse protection for industrial switchboards and high-current distribution applications.
This configuration uses the 22 operating mechanism positioned between the poles and is designed for DIN size 3 fuse links. The fourth pole is positioned on the left and is configured as a switched solid link, providing coordinated four-pole switching while the fused poles accommodate the appropriate DIN fuse links.
The OS800D22N1 is front operated and base mounted, with 39 mm lug terminals. This specific configuration is supplied without a handle and shaft, allowing suitable operating accessories to be selected separately to suit the switchboard or enclosure design.

- Designed in accordance with IEC 60947-3.
Reliable High-Current DIN Fuse Protection and Isolation
Switch fuses combine manual circuit isolation with fuse-based overcurrent protection. This arrangement enables electrical circuits to be positively disconnected for operation or maintenance while correctly selected DIN fuse links provide protection against potentially damaging overcurrent and short-circuit conditions.
The ABB OS800D22N1 provides an 800 A four-pole solution using DIN size 3 fuse links. Its front-operated mechanism between the poles, switched solid-link fourth pole and robust base-mounted construction make it suitable for high-current switchboards and distribution assemblies where the operating handle and shaft are selected separately for the installation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- High-current feeder circuits.
- Four-pole circuit switching and isolation.
- DIN fuse-protected industrial power circuits.
- Industrial machinery and production facilities.
- OEM switchgear and electrical distribution assemblies.
