Why Choose the ABB OTM200E3CM230C Motorised Change-Over Switch?
The ABB OTM200E3CM230C is a 200 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 power distribution.
The OTM200E3CM230C provides I-O-II open-transition operation, giving the switching sequence a defined OFF position between source I and source II. Its integrated motor operator is designed for a 220–240 V AC operating supply, enabling remotely controlled source transfer while retaining manual operating capability through the supplied handle.
Rated at 200 A with a 3-pole configuration, the OTM200E3CM230C provides 200 A AC-23A switching capability at 400–415 V and 110 kW AC-23A operational power at 400–415 V. The switch is supplied with a manual operating handle, terminal bolt hardware and male connectors for the control circuits.

Reliable 200 A Motorised Power Source Change-Over
The ABB OTM200E3CM230C enables power-source selection to be controlled electrically through its integrated motor operator. Its I-O-II open-transition mechanism mechanically isolates the two source positions during transfer, supporting dependable switching between separate supplies in low-voltage distribution systems.
With a 200 A rating, three-pole construction and 220–240 V AC motor operator, the OTM200E3CM230C is suited to motorised three-phase source-transfer arrangements. Manual operating capability remains available through the supplied handle, providing a practical local operating method when motorised control is not being used.
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.

Frequently Asked Questions
What is the ABB OTM200E3CM230C used for?
The ABB OTM200E3CM230C is a 200 A 3-pole motorised change-over switch designed for controlled transfer between two electrical power sources in low-voltage distribution systems.
What is the rated current of the OTM200E3CM230C?
The OTM200E3CM230C has a rated current of 200 A and an AC-23A operational current rating of 200 A at 400–415 V.
What motor operating voltage does the OTM200E3CM230C use?
The integrated motor operator is designed for a 220–240 V AC operating supply.
What does I-O-II operation mean on the OTM200E3CM230C?
I-O-II identifies the two source positions and the intermediate OFF position. The OTM200E3CM230C uses open-transition operation so the switch passes through the disconnected position when transferring between source I and source II.
Can the ABB OTM200E3CM230C be operated manually?
Yes. ABB supplies the OTM200E3CM230C with a manual operating handle, allowing local operation in addition to its integrated motorised control.
