OT2500E03CP ABB 2500A 3-Pole Manual Change-Over Switch

Why Choose the ABB OT2500E03CP Manual Change-Over Switch?

The ABB OT2500E03CP is a heavy-duty 3-pole 2500 A manual change-over switch designed for reliable switching between two power sources in high-current electrical distribution systems. As part of the ABB OT change-over switch range, it provides dependable manual source selection for industrial, commercial and infrastructure power installations.

The OT2500E03CP uses I-O-II operation with an open-transition, stable OFF position, allowing the connected load to be isolated between source positions. Its manual operating arrangement provides clear and straightforward control, while the handle can be padlocked in the O position to support safe isolation procedures.

With a rated current of 2500 A and a 3-pole configuration, the OT2500E03CP is engineered for demanding high-current applications. The switch is supplied as a manual change-over solution with a black plastic pistol-type operating handle and is suitable for installations requiring robust source transfer without automatic or motor-operated switching.

Reliable Manual Power Source Change-Over

Manual change-over switches allow electrical loads to be transferred between two independent power sources while maintaining controlled electrical isolation. The I-O-II operating sequence of the ABB OT2500E03CP provides a defined OFF position between the two connected sources, making it suitable for applications where open-transition switching is required.

The ABB OT change-over range is designed for electrical distribution applications requiring reliable source selection and isolation. With its high 2500 A current rating and robust 3-pole construction, the OT2500E03CP is particularly suited to large switchboards, industrial distribution systems and installations incorporating normal and alternative power supplies.

Typical Applications

• Main and alternative power source selection.
• Industrial low-voltage distribution switchboards.
• Generator and mains change-over systems.
• Commercial and infrastructure power distribution.
• High-current electrical distribution assemblies.
• Industrial plants and manufacturing facilities.
