Blue Sea Systems SI-ACR Automatic Charging Relay 7610, 12/24V DC, 120 Amp

The Blue Sea Systems SI-ACR (7610) is an Automatic Charging Relay that combines battery banks automatically while charging and isolates them automatically when discharging, so house loads never draw down the engine start battery. It operates on a 12/24 volt auto-ranging voltage input, making it suitable for both 12V and 24V DC electrical systems, and supports high-output alternators up to 120 amperes.

Sensitive electronics are protected because the SI-ACR provides temporary isolation of house loads from the engine circuit during engine cranking, preventing voltage drop from affecting connected equipment. The relay uses hermetically sealed, vaporproof electrical contacts rated for 120 amps, with contacts made of stainless steel or tinned material for corrosion resistance in a marine environment. It is ignition protected, meaning it is safe for installation aboard gasoline powered boats. The unit switches automatically with a minimum switching voltage of 13 volts DC and an operating time of 10 seconds, connects via quick connect terminals (2 terminals total), and can be floor mounted or mounted without a bracket.
