The A702AAP is a reverse current cutout relay assembly designed for 28 VDC electrical systems. It features a nominal voltage rating of 28 volts DC with a current rating of 600 amperes and reverse current settings adjustable between 18 and 35 amperes. The assembly incorporates multiple relay contacts including voltage relay contacts, a main contactor, differential relay contacts, and a reverse current coil that opens when the switch is de-energized or upon detection of reverse current. The device has a maximum weight of 3.0 lbs and includes mounting studs (3.8/24 UNF-2A and 10-32 UNF-2A) with terminal tolerances of ±0.06 inches. This cutout is commonly used in aircraft and aerospace electrical systems to protect battery charging circuits and prevent reverse current flow in DC power distribution networks.
