Why Choose the ABB OTM2500E3CM230C Motorised Changeover Switch?
The ABB OTM2500E3CM230C is a heavy-duty 2500 A three-pole motorised changeover switch designed for reliable transfer between two power sources in high-current electrical distribution systems. As part of the ABB OT motorised changeover switch range, it combines robust switching performance with electrically operated source transfer for industrial and commercial power installations.
The OTM2500E3CM230C provides I-0-II changeover operation, allowing a connected load to be switched between two separate supplies through a mechanically interlocked switching arrangement. Its integrated motor operator enables remote electrical operation, while a manual operating handle provides an alternative means of operating the switch when required.
With a rated current of 2500 A, three-pole configuration and a motor operator designed for a 220–240 V AC supply, the OTM2500E3CM230C is suited to high-capacity mains/generator transfer, alternative supply selection and power distribution applications requiring dependable motorised changeover functionality.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM2500E3CM230C provide a controlled means of transferring electrical loads between two independent power sources. The I-0-II switching arrangement provides distinct positions for the first supply, isolation and the second supply, while mechanical interlocking prevents the two supplies from being connected simultaneously through the switch.
The ABB OTM range combines power switching and motorised operation in a compact assembly suitable for switchboards and distribution systems. The OTM2500E3CM230C can be electrically operated from a control system and also incorporates manual operating capability, making it suitable for installations requiring both remote source selection and local intervention.
Typical Applications
- Mains and generator power source changeover systems.
- High-current industrial electrical distribution boards.
- Commercial and infrastructure power distribution systems.
- Backup and standby power installations.
- Generator and alternative supply selection systems.
- Switchboards requiring remote motorised source changeover.
