Why Choose the ABB OTM63F4CMA230V Motorised Changeover Switch?
The ABB OTM63F4CMA230V is a compact 63 A four-pole motorised changeover switch designed for controlled transfer between two electrical power sources. Part of the ABB OT motorised changeover switch range, it combines a mechanically interlocked changeover switching arrangement with an integrated motor operator for remote source selection in industrial and commercial electrical distribution systems.
The OTM63F4CMA230V provides open-transition changeover operation, ensuring the connected source is disconnected before the alternative source is connected. Its motor operator is designed for a broad 110–240 V AC/DC operating range, while the switch is also supplied with a handle for manual operation and male connectors for the control circuits.
With a rated current of 63 A, a four-pole configuration and a rated power of 43 kVA at 400 V, the OTM63F4CMA230V provides a compact solution for mains/generator, standby and alternative power source changeover applications requiring remote motorised operation.

Reliable Motorised Power Source Changeover
The ABB OTM63F4CMA230V provides a controlled method of transferring electrical loads between two independent power sources. Its open-transition switching arrangement disconnects the active source before connecting the alternative supply, maintaining separation between the two sources during normal changeover operation.
The integrated motor operator supports a 110–240 V AC/DC control supply, enabling remote source selection from a suitable control system. A supplied manual operating handle provides local switching capability when required, while the four-pole arrangement makes the OTM63F4CMA230V suitable for installations requiring four conductors to be transferred together.
Typical Applications
- Mains and generator power source changeover systems.
- Standby and emergency power distribution.
- Industrial electrical switchboards.
- Commercial building electrical distribution.
- Alternative supply selection systems.
- Four-pole power transfer installations requiring remote motorised operation.
