Blue Sea Auto Charging Relay w/ Manual Control

Blue Sea ML-ACR Auto Charging Relay w/ Manual Control

The Blue Sea Auto Charging Relay is a 500 Amp magnetic latching (bi-stable) relay that automatically combines batteries during charging and isolates batteries when discharging and when starting engine. The manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing. The ML-ACR relay draws very low current in the "ON" or "OFF" states, and draws moderate current for a very short time when changing state. Start Isolation (SI) can be configured for temporary isolation of house loads from engine circuit during engine cranking to protect sensitive electronics. Engine Isolation (EI) can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output. The Blue Seas Auto Charging Relay also features label recesses for circuit identification.
