OS630FP-A ABB 630 A 4-Pole Steel Enclosed Switch Fuse IP65

Why Choose the ABB OS630FP-A 630A 4-Pole Enclosed Switch Fuse?

The ABB OS630FP-A is a heavy-duty 630 A, 4-pole enclosed switch fuse designed for dependable switching, isolation and fuse-protected power distribution in industrial and commercial low-voltage installations. As part of the ABB 311027-OT Switches product group, it combines ABB OS switch-fuse technology with a robust steel enclosure for demanding electrical distribution applications.

The OS630FP-A provides four-pole switching and is supplied in an IP65-rated mild-steel enclosure. The enclosure incorporates removable top and bottom gland plates, a hinged door with lock and a padlockable pistol-grip operating handle, providing a practical complete assembly for surface-mounted electrical isolation.

With a rated current of 630 A and an AC-23 motor switching rating of 355 kW at 400 V, the OS630FP-A is suitable for substantial industrial loads. The enclosure measures approximately 600 × 600 × 300 mm, has a powder-coated RAL 7035 finish and accepts BS88 C1/C2 fuse links.
