Why Choose the ABB OS630DS30 Switch Fuse?
The ABB OS630DS30 is a heavy-duty 630 A 3-pole side-operated DIN 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 DIN fuse protection for demanding industrial and commercial electrical installations.
This configuration features the 30 operating mechanism positioned on the right side and is designed for DIN size 3 fuse links. The side-operated arrangement is particularly useful in switchboard designs where access or equipment layout makes side operation preferable to conventional front operation.
With a rated current of 630 A, a 3-pole configuration and a rated operational voltage of 690 V AC, the OS630DS30 is suitable for substantial three-phase low-voltage loads. This specific version is supplied without a handle and shaft, allowing the appropriate operating accessories to be selected separately for the installation.
Key Advantages
- Heavy-duty 630 A switch fuse for high-current power distribution.
- 3-pole configuration for three-phase switching and isolation.

Reliable Side-Operated Switching and Fuse Protection
Switch fuses combine manual circuit isolation with fuse-based overcurrent protection. This allows electrical circuits to be positively disconnected for operation or maintenance while correctly selected DIN fuse links provide protection against damaging overcurrent and short-circuit conditions.
The ABB OS630DS30 provides a 630 A three-pole solution specifically configured for side operation. Its DIN size 3 fuse compatibility, right-side 30 mechanism and handle-free configuration make it suitable for purpose-built industrial switchboards where the operating handle and shaft are selected separately to suit the enclosure and installation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- High-current three-phase feeder circuits.
- Industrial machinery and production equipment.
- Switchboards requiring right-side operation.
- OEM switchgear and electrical distribution assemblies.
