Why Choose the ABB OS100GA4LUU2FZ 100 A 2-Pole Enclosed Switch Fuse?
The ABB OS100GA4LUU2FZ is a robust 100 A 2-pole enclosed switch fuse designed for switching, isolation and fuse-based circuit protection in industrial and commercial low-voltage electrical systems. Part of the ABB OS fuse switch range, it combines a front-operated switch fuse with a durable steel-sheet enclosure for dependable operation in demanding installations.
This enclosed switch fuse uses the British Standard (BS) fuse system and accepts BS88 A2–A4 fuse links. Its steel enclosure provides IP65 protection, making the assembly suitable for environments where protection against dust and water ingress is required. A black pistol-type operating handle with I-0 and ON-OFF indication provides clear external control.
With a 100 A enclosed thermal current rating and 2-pole configuration, the OS100GA4LUU2FZ is suitable for distribution, feeder isolation and equipment protection applications. The enclosure measures approximately 400 × 250 × 180 mm (H × W × D) and is supplied with neutral and protective-earth terminals plus blank cable-entry positions.
