Why Choose the ABB OTM160E3WCM230C Motorised Change-Over Switch?
The ABB OTM160E3WCM230C is a 160 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 an integrated motor operator with robust switching performance for industrial, commercial and infrastructure applications.
The OTM160E3WCM230C provides I-O-II open-transition operation, ensuring the connected source is disconnected before the alternative source is connected. This model uses a 220–240 V AC motor operating supply and includes a handle for manual operation, allowing local operation when required.
Rated at 160 A with a 3-pole configuration, the OTM160E3WCM230C is the extended-phase-distance version of the OTM160 motorised change-over platform. It provides 160 A AC-23A switching capability and 90 kW rated operational power at 400–415 V, making it suitable for demanding three-phase source-transfer systems.
Key Advantages
- 160 A motorised change-over switch for remotely controlled power source transfer.
- 3-pole configuration designed for three-phase electrical systems.

Reliable Motorised Open-Transition Power Source Change-Over
Motorised change-over switches enable source-transfer commands to be initiated electrically, supporting remote and system-controlled switching in low-voltage power distribution. The ABB OTM160E3WCM230C combines an integrated motor operator with I-O-II open-transition switching, mechanically isolating the two power sources during the transfer sequence.
The OTM160E3WCM230C combines a 160 A rating with three-pole construction, extended phase distance and 90 kW AC-23A operational power at 400–415 V. A supplied manual operating handle provides local operating capability when required, complementing the normal motorised operation.
Typical Applications
- Motorised mains and alternative power source selection.
- Generator and mains change-over systems.
- Industrial low-voltage distribution switchboards.
- Commercial building electrical distribution.
- Remote three-phase source-transfer systems.
- Manufacturing, infrastructure and process installations.
