OS160GD04N2 Fuse Switch Disconnector (4P, 160 A)
The OS160GD04N2 is a 4-pole fuse switch disconnector from the ABB OS range with a rated current of 160 A. It combines load switching and short-circuit protection in one compact device, accommodating DIN blade-type fuse links for main and branch protection in distribution systems.
The front-operated switch-disconnector is built for panel-front mounting with door interlock capability and a full range of accessories, including auxiliary contacts, phase barriers and shaft extensions. Its four-pole configuration supports three-phase plus neutral switching in demanding industrial and commercial networks.
Typical applications include main disconnects, distribution feeders and machine supply isolation where fuse-based short-circuit protection is required.
