Why Choose the ABB OS400FP-A 400A 4P Enclosed Switch Fuse?
The ABB OS400FP-A is a heavy-duty 400 A 4-pole enclosed switch fuse designed for reliable load switching, electrical isolation and fused protection in low-voltage industrial and commercial power distribution systems. Part of the ABB OS switch fuse range and ABB's 311019-Metal Enclosed (Loadbreak) product group, it combines high-current switching with fuse protection inside a robust steel enclosure.
The OS400FP-A provides a practical means of isolating electrical circuits while incorporating fuse protection for downstream cables, machinery and electrical equipment. Its IP65 steel enclosure provides a high degree of protection against dust and water ingress, while the textured powder-coated RAL 7035 finish provides a durable surface for demanding indoor industrial environments.
Rated at 400 A, the OS400FP-A features a four-pole configuration and accepts BS88 B1–B4 fuse sizes. Its 600 × 400 × 250 mm enclosure incorporates top and bottom removable gland plates, a hinged locking door and a padlockable pistol-grip operating handle, providing a practical solution for secure high-current electrical isolation and distribution.

Reliable High-Current Switching, Isolation and Fuse Protection
Enclosed switch fuses such as the ABB OS400FP-A combine load switching, circuit isolation and fuse protection within a single assembly. This enables high-current electrical circuits to be disconnected for maintenance and servicing while correctly selected fuse links provide protection for downstream cables and equipment against overcurrent and short-circuit conditions.
The OS400FP-A is designed for demanding industrial power distribution applications where dependable isolation and robust construction are essential. Its steel enclosure, locking hinged lid and padlockable operating handle provide a secure switching solution, while the four-pole configuration allows all four conductors to be switched simultaneously when required by the installation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and local high-current electrical isolation.
- Four-pole distribution and isolation circuits.
- Industrial machinery and production equipment supplies.
- Motor, cable and feeder protection circuits.
- Commercial and industrial switchgear installations.
- Distribution boards and electrical control systems.
