The ABB OS800B22N1 is a heavy-duty 800 A 4-pole switch fuse designed for reliable switching, isolation and fuse protection in demanding low-voltage power distribution systems. Part of the ABB OS fuse switch range, it uses the British Standard fuse system and provides a robust solution for high-current industrial and commercial installations.
This configuration features the 22 operating mechanism positioned between the poles and accommodates C1–C3 mechanical fuse sizes. 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 fuse links.
The OS800B22N1 is front operated and base mounted, with 39 mm lug terminals. This specific version is supplied without a handle and shaft, allowing suitable operating accessories to be selected separately to suit the switchboard or enclosure design.
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 fuse links provide protection against potentially damaging overcurrent and short-circuit conditions.
The ABB OS800B22N1 provides an 800 A four-pole solution using British Standard C1–C3 fuse links. Its front-operated mechanism between the poles, switched solid-link fourth pole and base-mounted construction make it suitable for high-current switchboards and distribution assemblies where the handle and shaft are selected separately for the installation.
