Why Choose the ABB OTM100F3CMA230V Motorised Change-Over Switch?
The ABB OTM100F3CMA230V is a 100 A 3-pole motorised change-over switch designed for controlled transfer between two electrical power sources in low-voltage distribution systems. Part of the ABB OT change-over switch range, it combines motorised operation with the ability to operate the switch manually when required.
The OTM100F3CMA230V uses an open-transition change-over arrangement, ensuring one source is disconnected before the alternative source is connected. Its motor operator accepts a 110–240 V AC/DC operating supply, making the switch suitable for remotely controlled source-transfer arrangements in industrial and commercial switchboards.
Rated at 100 A with a 3-pole configuration, the OTM100F3CMA230V is supplied with a handle for manual operation, terminal bolt hardware and male connectors for the control circuit. Its compact base-mounted design provides an integrated motorised switching solution for three-phase power distribution applications.

Reliable Motorised Power Source Change-Over
Motorised change-over switches enable electrical power sources to be selected through an electrically operated switching mechanism rather than requiring routine direct manual operation. The ABB OTM100F3CMA230V combines a motor operator with an open-transition change-over mechanism, making it suitable for control systems that require remote source switching.
The OTM100F3CMA230V also includes a manual operating handle, providing local operating capability when required. Its 100 A rating, three-pole construction and 110–240 V AC/DC motor supply range make it a versatile solution for motorised source-transfer arrangements in low-voltage distribution systems.
Typical Applications
- Motorised mains and alternative source selection.
- Generator and mains change-over systems.
- Industrial low-voltage distribution switchboards.
- Commercial building power distribution.
- Remote three-phase source-transfer systems.
- Infrastructure and manufacturing electrical installations.
