Why Choose the ABB OT250E04CFP Manual Change-Over Switch?
The ABB OT250E04CFP is a high-performance 250 A 4-pole manual change-over switch designed for fast and reliable transfer between two electrical power sources. As part of the ABB OT change-over switch range, it combines dependable manual operation with a fast-transition mechanism for demanding industrial and commercial power distribution applications.
The OT250E04CFP provides I-O-II operation and uses a fast-transition mechanism designed to minimise the OFF time when transferring between positions I and II. Its 90° operating angle enables rapid switching, making it suitable for installations where the interruption period during manual source transfer needs to be kept short.
With a rated current of 250 A and a 4-pole configuration, the OT250E04CFP provides simultaneous switching across four poles. The switch is supplied with a black plastic pistol-type operating handle and shaft, providing a complete manual operating arrangement for installation in electrical distribution equipment.

Fast Manual Power Source Change-Over
Fast-transition change-over switches are designed to transfer loads rapidly between two electrical sources while retaining a defined I-O-II operating sequence. The ABB OT250E04CFP uses a 90° operating movement to achieve fast switching, with the OFF time between transfer from I to II or II to I designed to be as low as 20 ms.
The ABB OT fast-transition range is suitable for electrical distribution systems where reliable manual source selection and reduced transfer interruption are important. The 250 A rating and four-pole arrangement make the OT250E04CFP well suited to three-phase systems requiring switching of an additional conductor alongside the three phases.
Typical Applications
- Mains and alternative power source change-over systems.
- Generator and mains source selection.
- Industrial low-voltage distribution switchboards.
- Commercial electrical distribution systems.
- Four-pole power transfer applications.
- Industrial plants and manufacturing facilities requiring fast manual source transfer.
