Product Description
The 770-537 is a current sensing relay that monitors electrical circuit current in aircraft DC systems. When current exceeds a preset threshold, the relay automatically switches its contacts to trigger load shedding, contactor interlocks, or protection circuits. Commonly installed in bus management and electrical protection systems on aircraft like the Hawker 800 series.
Installation requires setting the current threshold per the aircraft wiring diagram and maintenance manual, with verification against the Illustrated Parts Catalog for system compatibility.
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.
