Why Choose the ABB OS125GB11 Fuse Switch Disconnector?
The ABB OS125GB11 is a robust 125 A, 2-pole fuse switch disconnector designed for reliable switching, isolation and fuse protection in industrial low-voltage electrical systems. As part of the established ABB OS switch fuse series, it combines manual circuit isolation with fuse-based protection for dependable operation in distribution and machinery applications.
This front-operated switch fuse is designed for British Standard A2–A4 fuse links and provides a practical modular solution for electrical panels and switchboards. Its two-pole arrangement allows simultaneous switching and isolation of two conductors, while the fuse-switch construction enables suitable fuse links to provide overcurrent and short-circuit protection.
Rated at 125 A, the OS125GB11 is supplied without the operating mechanism module, handle and shaft, allowing the appropriate ABB operating accessories to be selected separately for the application. This configuration is particularly useful for panel builders and OEMs requiring flexibility when configuring the operating arrangement of an electrical enclosure.
