Why Choose the ABB OTM2500E4CM230C Motorised Changeover Switch?
The ABB OTM2500E4CM230C is a heavy-duty 2500 A four-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 power switching with electrically operated source transfer for demanding industrial, commercial and infrastructure installations.
This motorised changeover switch uses an open-transition switching arrangement and provides I-0-II operation for controlled selection between two electrical supplies. The integrated motor operator enables remote electrical switching, while ABB supplies the switch with a handle for manual operation, terminal bolt hardware and control-circuit connectors.
With a rated current of 2500 A, a four-pole configuration and a motor operating voltage of 220–240 V AC, the OTM2500E4CM230C is designed for high-capacity mains/generator changeover, alternative supply selection and other power-transfer applications where all four poles require switching.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM2500E4CM230C provide a controlled method of transferring electrical loads between two independent power sources. Its open-transition arrangement disconnects one source before connection to the alternative source, while the I-0-II operating sequence provides clearly defined source I, OFF and source II positions.
The four-pole OTM2500E4CM230C is particularly suited to installations where four conductors must be switched during source transfer. Its integrated motorised mechanism enables remote control from an appropriate control system, while the supplied manual operating handle provides local operating capability for commissioning, maintenance and operational requirements.
Typical Applications
- Mains and generator power source changeover systems.
- High-current industrial electrical distribution boards.
- Commercial and infrastructure power distribution systems.
- Standby and emergency power installations.
- Alternative supply selection systems.
- Switchboards requiring four-pole motorised source changeover.
