Why Choose the ABB OT1250E22CP Manual Change-over Switch?
The ABB OT1250E22CP is a heavy-duty 4-pole 1250 A manual change-over switch designed for dependable manual transfer between two electrical power sources. As part of the ABB OT Change-over Switches range, it provides I-O-II operation with a stable OFF position for industrial power distribution, switchboards and high-current supply change-over applications.
Designed for open-transition switching, the OT1250E22CP disconnects one source before connecting the alternative source. Its front-operated mechanism positioned between the poles provides a practical arrangement for switchboard installations. The switch is supplied with a black plastic IP65 I-O-II pistol handle, operating shaft and bolt set for cable connection, with the handle padlockable in the O position.
With a rated operational current of 1250 A and a 4-pole configuration, the OT1250E22CP is engineered for demanding low-voltage power distribution systems. At 400–415 V, the switch provides an AC-23A rating of 1250 A / 710 kW, making it suitable for high-current industrial and commercial change-over duties.

Reliable Four-pole Manual Power Source Change-over
Manual change-over switches provide a controlled method of transferring an electrical load between two power sources. The ABB OT1250E22CP uses open-transition I-O-II operation, ensuring one source is disconnected before the alternative source is connected while providing a stable OFF position between the two operating states.
The four-pole configuration enables four conductors to be switched together, while the front-operated mechanism between the poles supports practical integration into high-current switchboards. With its 1250 A rating, robust switching performance and secure padlocking and interlocking features, the OT1250E22CP is suitable for main distribution boards, generator change-over systems and demanding industrial power installations.
Typical Applications
- Main electrical distribution switchboards.
- Mains-to-generator manual change-over systems.
- Four-pole three-phase and neutral power distribution systems.
- Industrial and commercial power installations.
- Backup and alternative power source selection.
- OEM switchboards and high-current electrical panels.
