Why Choose the ABB OTM800E3CM230C Motorised Changeover Switch?
The ABB OTM800E3CM230C is a robust 800 A 3-pole motorised changeover switch designed for reliable switching between two electrical power sources in industrial and commercial power distribution systems. As part of the ABB OT motorised changeover switch range, it combines high-current switching capability with an integrated motor operator for convenient remote operation.
This motorised changeover switch uses an open-transition I-O-II switching arrangement, providing controlled transfer between two power sources with a defined OFF position. It is suitable for applications such as mains-to-generator changeover, alternative supply selection and power distribution systems where dependable source switching is required.
The OTM800E3CM230C has a rated current of 800 A, a 3-pole configuration and an integrated motor operator rated for 220–240 V AC. It is supplied with a handle for manual operation, terminal bolt hardware, control-circuit connectors, a handle storage clip and spare fuses.

Reliable Motorised Power Source Transfer
Motorised changeover switches provide a practical method of transferring electrical loads between alternative power sources. The ABB OTM800E3CM230C combines the switching mechanism and motor drive in one assembly, allowing the changeover operation to be initiated remotely from a control system or operating station.
Its I-O-II operating sequence provides an open transition between sources, while the supplied manual handle allows local manual operation when necessary. The high current rating and robust switching characteristics make this model particularly suitable for substantial industrial and commercial electrical distribution installations.
Typical Applications
- Mains-to-generator changeover systems.
- Alternative mains supply switching.
- Industrial power distribution boards.
- Commercial and infrastructure electrical systems.
- Generator and standby power installations.
- Remote-operated power source selection.
