Why Choose the ABB OMD300E480C-A1 Automatic Transfer Switch Control Unit?
The ABB OMD300E480C-A1 is a stand-alone automatic transfer switch (ATS) control unit designed for use with compatible ABB OTM motorised change-over switches. Identified by ABB order code 1SCA123790R1001, the OMD300 provides the automatic control functionality required to create an ABB automatic transfer switching system for standby and alternative-source power applications.
The OMD300E480C-A1 is suitable for use with ABB OTM40–3200 motorised change-over switches. By combining the OMD300 controller with the appropriate motorised change-over switch and required sensing and connection accessories, system designers can create an automatic transfer arrangement that manages switching between available electrical power sources.
Designed for flexible switchboard integration, the controller can be mounted on a panel door or DIN rail. ABB supplies the OMD300E480C-A1 with the control unit, PCB connectors and two OMZD1 fasteners for door mounting, providing the principal control components required for integration with compatible OTM switching equipment.

Automatic Transfer Control for ABB Motorised Change-Over Switches
An automatic transfer control unit provides the control logic needed to operate a compatible motorised change-over switch as part of an automatic transfer system. When combined with the appropriate ABB OTM switching device and required sensing accessories, the OMD300E480C-A1 supports automatic management of source transfer for installations using normal and alternative electrical supplies.
For smaller OTM40–125_CMA configurations, the appropriate motorised change-over switch and terminal clamp sets with voltage-sensing connections are ordered separately. For OTM160–3200_CM installations, the compatible motorised change-over switch, voltage-sensing connectors and auxiliary contacts are selected separately to complete the ATS assembly.
Typical Applications
- Automatic transfer switch assemblies.
- Utility and standby generator change-over systems.
- Industrial power-distribution switchboards.
- Commercial and infrastructure backup-power systems.
- Motorised source change-over installations.
- OEM electrical control and transfer panels.
- Critical and alternative-source power distribution systems.
