Why Choose the ABB OS125GBS40N2 Fuse Switch Disconnector?
The ABB OS125GBS40N2 is a robust 125 A, 4-pole side-operated fuse switch disconnector designed for reliable switching, isolation and fuse protection in industrial low-voltage electrical distribution systems. As part of the proven ABB OS switch fuse series, it provides dependable manual isolation combined with fuse-based circuit protection for machinery, switchboards and power distribution applications.
This model features a side-operated configuration, making it particularly suitable for installations where the operating mechanism needs to be positioned at the side of a panel or enclosure. Its four-pole arrangement incorporates an N2 non-fused switched neutral on the right side, allowing coordinated switching of the neutral together with the fused phase conductors.
With a rated current of 125 A, the OS125GBS40N2 is designed for British Standard A2–A4 fuse links. This version is supplied without the operating handle and shaft, enabling compatible ABB operating accessories to be selected separately to suit the enclosure and installation requirements.
