Why Choose the ABB OT400E04CP 400 A 4-Pole Changeover Switch?
The ABB OT400E04CP is a robust and reliable 400 A four-pole manual changeover switch designed for safe and dependable switching between two electrical power sources. As part of the ABB OT manual changeover switch series, it provides a practical solution for industrial electrical distribution, generator changeover installations and commercial power supply selection applications.
The OT400E04CP features a three-position I–0–II operating mechanism with a stable central OFF position. Its open-transition switching arrangement ensures that the selected source is disconnected before the alternative source is connected, preventing intentional simultaneous connection of the two supplies. The switch is manually operated and incorporates a padlockable OFF position and door interlocking functionality to support safe operation and maintenance procedures.
With a rated operational current of 400 A, four switching poles and an AC-23A utilisation rating of 400 A / 220 kW at 400–415 V AC, the OT400E04CP is suitable for demanding industrial power switching applications. It is supplied with a black plastic IP65-rated I–0–II pistol handle, operating shaft and bolt set for cable connections, providing a complete manual operating arrangement for integration into suitable electrical switchboards and distribution assemblies.

Reliable Manual Power Source Changeover for Electrical Distribution Systems
Manual changeover switches such as the ABB OT400E04CP enable electrical installations to select between two independent power supplies using a mechanically operated switching arrangement. The I–0–II mechanism provides three distinct states: source I connected, both sources disconnected, or source II connected. The open-transition design ensures that the first source is disconnected before the second source is connected, making it suitable for appropriately designed mains and generator changeover systems.
The ABB OT400E04CP is designed for installations requiring a substantial 400 A switching capacity and four-pole isolation between alternative supplies. Its padlockable OFF position, door interlocking arrangement and IP65-rated operating handle support safe manual operation in industrial switchboards. The supplied shaft and connection hardware simplify integration into electrical distribution equipment, while the robust mechanical construction provides dependable switching for industrial facilities, commercial buildings and backup power applications.
