Why Choose the ABB OS630BS03K Switch Fuse?
The ABB OS630BS03K is a heavy-duty 630 A 3-pole side-operated switch fuse designed for dependable switching, isolation and fuse protection in low-voltage power distribution systems. As part of the ABB OS fuse switch range, it combines manual circuit isolation with British Standard fuse protection for demanding industrial and commercial electrical installations.
This configuration features the 03 operating mechanism on the left side and a direct-mounted handle, providing convenient local operation where a side-operated arrangement is required. The switch fuse is designed for British Standard C1–C2 fuse sizes and uses a base-mounted construction suitable for integration into switchboards and power distribution assemblies.
With a rated current of 630 A and a 3-pole configuration, the OS630BS03K is suitable for high-current three-phase circuits requiring reliable isolation and fuse protection. Its side-operated design, left-side mechanism and direct-mounted handle make it particularly suitable for switchboard layouts where conventional front operation is not preferred.

Reliable Side-Operated Switching and Fuse Protection
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 OS630BS03K provides a 630 A three-pole solution specifically configured for side operation. Its left-side mechanism, direct-mounted handle and C1–C2 British Standard fuse compatibility make it suitable for industrial switchboards and power distribution assemblies requiring dependable high-current three-phase isolation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- High-current three-phase feeder circuits.
- Industrial machinery and production equipment.
