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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea
