Blue Sea Systems 7622 ML-ACR 12V DC 500A Automatic Charging Relay with Manual Control, Gray

The Blue Sea Systems 7622 is a 12V DC, 500 Amp ML-ACR (Automatic Charging Relay) designed to automatically combine two large battery banks for charging and separate them once the engine is shut off, protecting house loads from being drawn down by the starting battery. Unlike a standard automatic-only ACR, the 7622 adds a manual control switch that lets the operator combine or isolate the battery banks with or without power present, including a LOCK OFF position for safe servicing of the electrical system.

The relay uses a Deutsch DTM connector and normally-closed, silver-alloy contacts rated for 500 amps of continuous current, with a 12 volt coil and a 12 volt minimum switching voltage. It is built to marine-grade electrical equipment and battery isolator standards and is intended for surface mounting near the battery banks it manages. The 7622 includes the ML-Series Remote Control Contura Switch (PN 2146), which provides the manual override function from a remote helm or panel location.

This ACR is suited for boats and other 12 volt DC systems running dual large battery banks where automatic charge combining plus a manual override for servicing or emergency use is required.
