Why Choose the ABB OT400U22P Switch Disconnector?
The ABB OT400U22P is a robust 400 A four-pole UL switch disconnector designed for reliable switching and electrical isolation in industrial low-voltage power systems. As part of the established ABB OT switch-disconnector series, it combines high-current switching capability with a four-pole configuration for demanding distribution, machinery and control applications.
The OT400U22P features a mechanism positioned between the poles in ABB's 22 mechanism configuration. It is front operated, base mounted and equipped with lug terminals, while the fourth pole is positioned on the right and switches simultaneously with the other poles. The supplied configuration includes a black operating handle and shaft for straightforward integration into an electrical assembly.
Rated at 400 A, the OT400U22P supports a maximum operating voltage of 600 V under UL/CSA ratings. It is designed to meet UL 98 and CSA C22.2 No. 4 requirements as well as IEC 60947-3, making it suitable for industrial installations requiring a recognised UL switch-disconnector solution.
