Why Choose the ABB OS630BS04N2 Switch Fuse?
The ABB OS630BS04N2 is a heavy-duty 630 A 4-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 provides a robust solution for demanding industrial and commercial electrical installations.
This configuration features a side-operated mechanism and a 4-pole arrangement with an N2 non-fused switched neutral on the right side. It is designed for British Standard C1–C2 fuse sizes, making it suitable for high-current distribution circuits requiring coordinated phase and neutral isolation.
With a rated current of 630 A, the OS630BS04N2 is intended for substantial low-voltage loads where reliable manual isolation and fuse protection are required. This specific version is supplied without a handle, allowing the appropriate operating handle arrangement to be selected separately to suit the switchboard installation.

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 OS630BS04N2 provides a 630 A four-pole solution specifically configured for side operation. Its C1–C2 British Standard fuse compatibility, N2 non-fused switched neutral and handle-free configuration make it suitable for purpose-built industrial switchboards where the operating arrangement is selected separately to suit the installation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- High-current four-pole feeder circuits.
- Industrial machinery and production equipment.
- Switchboards requiring side-operated circuit isolation.
- OEM switchgear and power distribution assemblies.
