Why Choose the ABB OTM100F4CMA230V Motorised Change-Over Switch?
The ABB OTM100F4CMA230V is a 100 A 4-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 an integrated motor drive with four-pole switching for industrial, commercial and infrastructure power distribution applications.
The OTM100F4CMA230V provides I-O-II open-transition operation, disconnecting one source before the alternative source is connected. Its integrated motor operator has an operating voltage range of 110–240 V AC/DC, while the switch is also supplied with a handle for manual operation when local control is required.
Rated at 100 A, the OTM100F4CMA230V has four simultaneously switched poles, with the fourth pole positioned on the right-hand side. The compact base-mounted assembly includes male connectors for the control circuits and is engineered for straightforward integration into motorised source-transfer systems.

Reliable Four-Pole Motorised Power Source Change-Over
Motorised change-over switches enable power-source selection to be controlled electrically, making them suitable for switchboards where remote or system-controlled source transfer is required. The ABB OTM100F4CMA230V combines an integrated motor drive with I-O-II open-transition switching, providing a defined disconnection stage between the two electrical sources.
The OTM100F4CMA230V combines a 100 A rating with four simultaneously switched poles and a 110–240 V AC/DC motor operating range. Manual operating capability is retained through the supplied handle, providing a practical combination of motorised and local control for low-voltage power distribution systems.
Typical Applications
- Motorised mains and alternative power source selection.
- Generator and mains change-over systems.
- Industrial low-voltage distribution switchboards.
- Commercial building power distribution.
- Four-pole source-transfer systems.
- Infrastructure and manufacturing electrical installations.
