Product Introduction
The ABB OMD300E480C (OMD300E480C-A1) is an advanced automatic control unit designed specifically to manage motorized change-over switches, automatic transfer switches (ATS), and source-switching systems in critical power distribution frameworks.
Integrating built-in dual power source (DPS) monitoring logic, the controller continuously supervises primary and secondary voltage lines, frequency parameters, and phase symmetry. In the event of a primary grid failure or power degradation, the unit triggers seamless automated switching sequences to bring backup generation online, ensuring maximum uptime for critical facilities such as data centers, hospitals, telecommunications hubs, and continuous manufacturing plants.

Compliance & Standards Alignment
- Manufactured in strict compliance with international standards, including IEC 60947-6-1 (Automatic transfer switching equipment) and CE quality declarations.
- Conforms to environmental directives such as RoHS and REACH compliance profiles, designed for high reliability in heavy industrial power switchgear arrays.
Technical Note: The OMD300E480C monitors live medium/low voltage lines directly. Ensure that internal potential transformer (PT) scaling parameters and voltage thresholds match your exact grid architecture during initial software configuration to prevent nuisance switching or delayed transfer actions.
Storage & Asset Preservation Guidelines
- Store the control unit inside its original factory protective packaging in a clean, dry, climate-controlled indoor warehouse.
- Keep relative humidity under 85% (non-condensing) to protect sensitive internal microprocessors, relays, and display electronics from moisture ingress.
- Avoid heavy mechanical shock, vibration, or stacking excessive weight on top of the product carton.
Physical Installation Prerequisites
- Ensure that all main incoming power lines, generator feeders, and low-voltage control circuits connected to the switchgear are completely isolated, de-energized, and locked out (LOTO) prior to installation or wiring.
- Verify panel cutout dimensions if performing a front-door flush mount, ensuring proper sealing with the gasket to maintain panel rating integrity.
- Torque all screw terminals and multi-pin plug connectors securely to prevent intermittent contact or arc fault vulnerabilities under normal switchgear operation.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this ABB control unit?
A: Low-voltage switchgear accessories, automatic transfer controllers, and electrical monitoring relays typically classify under HS code 8538.90 (Parts suitable for use with electrical control apparatus) or 8537.10. Confirm final details with your customs broker.
Q: Is part OMD300E480C compatible with any motorized switch?
A: The OMD300 series is specifically engineered to interface with compatible ABB motorized change-over switches and ATS configurations (such as TruOne or OT/OTM lines depending on system integration specs). Always cross-reference your switchgear model datasheet.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, global supply chain tiers, and currency fluctuations; contact our technical sales desk for a formal, time-sensitive quotation.
