1SCA022837R8000 ABB 630A 4-Pole C1-C2 Switch Fuse

Why Choose the ABB OS630B22N1 Switch Fuse?

The ABB OS630B22N1 is a heavy-duty 630 A 4-pole switch fuse designed for reliable switching, isolation and fuse protection in low-voltage electrical distribution systems. As part of the ABB OS fuse switch range, it provides a robust solution for industrial switchboards, distribution assemblies and other demanding high-current applications.

This configuration features the 22 operating mechanism positioned between the poles and is designed for C1–C2 fuse sizes. The fourth pole incorporates a switched solid link, allowing coordinated four-pole switching while the fused poles provide protection through correctly selected fuse links.

With a rated current of 630 A and a 4-pole configuration, the OS630B22N1 is intended for substantial low-voltage loads requiring dependable isolation and fuse protection. This specific version is supplied without a handle and shaft, allowing the appropriate operating accessories to be selected separately for the switchboard installation.

Reliable High-Current Switching and Fuse Protection

Switch fuses combine manual circuit isolation with fuse-based overcurrent protection. This arrangement allows power 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 OS630B22N1 provides a 630 A four-pole solution with C1–C2 fuse compatibility, a mechanism positioned between the poles and a switched solid-link fourth pole. Its configuration is particularly suitable for industrial switchboards and power distribution assemblies where dependable high-current multi-pole isolation is required.

Typical Applications

• Industrial low-voltage power distribution systems.
• Main and sub-distribution switchboards.
• High-current feeder circuits.
• Four-pole circuit isolation applications.
• Industrial machinery and production facilities.
• OEM switchgear and electrical distribution assemblies.
