Why Choose the ABB OT250E04CP 250 A 4-Pole Manual Changeover Switch?
The ABB OT250E04CP is a robust 250 A 4-pole manual changeover switch designed for reliable source selection in low-voltage electrical distribution systems. As part of the ABB OT Changeover Switches range, it provides dependable manual switching between two electrical supplies for industrial switchboards, distribution panels, generator systems and alternative power installations.
This changeover switch provides I-O-II open-transition operation with a stable OFF position, ensuring that the circuit passes through isolation when changing between the two sources. Its four-pole construction enables four conductors to be switched simultaneously, while the fourth pole is switched with simultaneous operation.
Rated at 250 A, the OT250E04CP provides 250 A AC-21A, AC-22A and AC-23A switching capability at 380–415 V, with an AC-23A operational power rating of 140 kW at 400 V. It is supplied with a black plastic IP65 I-O-II pistol-type handle, operating shaft and bolt set for cable connection, providing a complete manual operating arrangement.

Reliable Four-Pole Power Source Changeover
Manual changeover switches provide a controlled method of selecting between two electrical supplies. The ABB OT250E04CP uses an I-O-II open-transition arrangement with a stable OFF position, ensuring that the switching sequence passes through isolation when transferring from one source to the other.
The four-pole construction enables four conductors to be switched simultaneously, making the OT250E04CP suitable for distribution systems requiring four-pole source transfer. Its 250 A rating, robust switching capability and supplied operating accessories make it a practical solution for industrial, commercial and infrastructure switchboards.
Typical Applications
- Main and alternative power supply changeover systems.
- Generator and mains source-selection systems.
- Industrial low-voltage distribution switchboards.
- Four-pole electrical distribution systems.
- Industrial machinery and plant power systems.
- Commercial and infrastructure electrical installations.
