Why Choose the ABB OS630D22N1P Switch Fuse?
The ABB OS630D22N1P is a heavy-duty 630 A 4-pole DIN switch fuse designed for reliable 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 DIN fuse protection for demanding industrial and commercial electrical installations.
This switch fuse features a front-operated 22 mechanism positioned between the poles and uses 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 circuit isolation while the fused poles provide overcurrent protection.
With a rated current of 630 A and a rated operational voltage of 690 V AC, the OS630D22N1P is designed for substantial low-voltage loads. It is base mounted, uses lug terminals and is supplied with a pistol handle and shaft, making it suitable for integration into industrial switchboards and power distribution assemblies.
Key Advantages
- Heavy-duty 630 A switch fuse for high-current power distribution.
- 4-pole configuration for coordinated multi-pole circuit isolation.

Reliable High-Current Switching and Fuse Protection
Switch fuses combine manual circuit isolation with fuse-based overcurrent protection. This arrangement enables power circuits to be positively disconnected for operation or maintenance while correctly selected fuse links provide protection against damaging overcurrent and short-circuit conditions.
The ABB OS630D22N1P provides a 630 A four-pole solution for DIN fuse systems. Its size 3 fuse compatibility, 22 mechanism between the poles, switched solid-link fourth pole and included pistol handle and shaft make it well suited to high-current industrial switchboards and low-voltage distribution assemblies.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- High-current feeder circuits.
- Four-pole circuit isolation applications.
- DIN fuse-protected industrial power circuits.
- OEM switchgear and electrical distribution assemblies.
