Why Choose the ABB OTM200E3CM24D Motorised Change-Over Switch?
The ABB OTM200E3CM24D 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 high-current switching with an integrated motor operator for industrial, commercial and infrastructure applications.
The OTM200E3CM24D provides I-O-II operation, with a defined OFF position between source I and source II. Its integrated motor operator is powered by 24 V DC, making this version particularly suitable for control systems and switchboards using a low-voltage DC control supply.
Rated at 200 A with a 3-pole configuration, the OTM200E3CM24D provides 200 A AC-23 switching capability at 400 V and 110 kW operational power at 400 V. ABB supplies the motorised change-over switch with a handle for manual operation, terminal bolt hardware, control-circuit connectors, a handle storage clip and spare fuses.

Reliable 24 V DC Motorised Power Source Change-Over
Motorised change-over switches enable electrical power-source selection to be controlled remotely rather than relying solely on local manual operation. The ABB OTM200E3CM24D combines an integrated 24 V DC motor operator with an I-O-II switching arrangement, providing source I, OFF and source II operating positions for controlled three-phase power transfer.
With its 200 A rating, three-pole construction and 110 kW AC-23 operational power at 400 V, the OTM200E3CM24D is suited to substantial low-voltage source-transfer duties. The included manual operating handle also provides local operating capability when required.
Typical Applications
- Motorised mains and alternative power source selection.
- Generator and mains change-over systems.
- Industrial low-voltage distribution switchboards.
- Commercial building electrical distribution.
- Three-phase source-transfer systems using 24 V DC control power.
- Manufacturing, infrastructure and process installations.
