Product Description
The AN3025-2 is an engine-generator cutout relay conforming to AN and MS27443 standards for DC electrical systems. This reverse-current relay automatically connects the generator to the battery during charging and isolates it when engine RPM drops, preventing battery backflow to the generator. Installed between the generator and battery in aircraft electrical systems, it protects charging circuits from damage caused by reverse current flow.
Installation and testing must follow the aircraft electrical maintenance manual and be verified against the Illustrated Parts Catalog for your specific aircraft model.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
