Why Choose the ABB OS100GB11 100 A 2-Pole BS Switch Fuse?
The ABB OS100GB11 is a 100 A, 2-pole, front-operated switch fuse designed for switching, isolation and fuse protection in low-voltage electrical distribution systems. Part of the ABB OS range, this GB-type model uses the British Standard fuse system and accepts BS88 A2-A4 fuse links.
The OS100GB11 features operating mechanism 11 positioned between the poles and a base-mounted construction for integration into switchboards, distribution panels and industrial control assemblies. Its lug-type terminals have a width of 20 mm, providing robust connection points for compatible conductors and terminals.
This version is supplied without an operating handle or shaft, allowing the appropriate operating accessories to be selected separately to suit the enclosure and installation arrangement. With a rated switching voltage of 690 V AC, the OS100GB11 provides a compact fused switching solution for demanding industrial applications.

Flexible Fused Switching and Isolation
Switch fuses combine manual circuit switching and isolation with replaceable fuse protection. The ABB OS100GB11 provides this functionality across two poles and accommodates British Standard A2-A4 fuse links, making it suitable for protected feeders and other low-voltage distribution circuits.
Because the OS100GB11 is supplied without a handle or operating shaft, these components can be selected separately to match the enclosure depth and operating requirements of the installation. The front-operated, base-mounted configuration and mechanism located between the poles provide a practical arrangement for integration into industrial switchgear.
