Why Choose the ABB OS630B22N2 Switch Fuse?
The ABB OS630B22N2 is a heavy-duty 630 A four-pole switch fuse designed for reliable switching, isolation and fuse-protected power distribution in demanding low-voltage electrical installations. Identified by ABB order code 1SCA022825R6580, this model forms part of the ABB OS fuse switch series and uses the British Standard fuse system.
The OS630B22N2 features front operation with the operating mechanism positioned between the poles (22). Its four-pole arrangement incorporates a switched fourth pole with solid link on the right side, making it suitable for three-phase distribution applications where simultaneous switching of the neutral conductor is required.
Rated at 630 A, this base-mounted switch fuse accepts British Standard C1–C2 fuse sizes and provides a robust solution for high-current switchboards and distribution assemblies. This specific version is supplied without handle and shaft, enabling the appropriate operating accessories to be selected separately for the installation.
