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.
Typical Applications
- Manual mains and generator power source changeover.
- Industrial electrical distribution switchboards.
- Commercial building power supply selection.

Frequently Asked Questions
What is the ABB OT400E04CP changeover switch used for?
The ABB OT400E04CP is a 400 A four-pole manual changeover switch used to select between two electrical power sources. It is commonly installed in industrial switchboards, mains and generator changeover systems and commercial electrical distribution equipment.
What is the current rating of the ABB OT400E04CP?
The OT400E04CP has a 400 A rated operational current. Its AC-21A/AC-22A rating is 400 A at up to 415 V AC, and its AC-23A rating is 400 A / 220 kW at 400–415 V AC.
How many poles does the ABB OT400E04CP have?
The ABB OT400E04CP has four switching poles, allowing it to be used in suitable three-phase and neutral changeover applications where all four conductors need to be switched.
What do the I–0–II positions mean on the ABB OT400E04CP?
The switch provides three operating positions. Position I connects the first supply, position 0 disconnects both supplies, and position II connects the alternative supply. The central OFF position is stable.
Does the ABB OT400E04CP use open-transition switching?
