Blue Sea 7620100 ML ACR Charging Relay 12V 500A w/Deutsch Connector 7620100

500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine.

Features:

• Automatically manages the charging of two large battery banks
• Allows paralleling of battery banks for emergency starting
• 500 Ampere continuous rating to support high-output alternators
• Magnetic Latch (ML)—ACR draws very low current (<40mA to monitor terminal voltage) in the "ON" or "OFF" states, and draws moderate current for very short time when changing state
• Dual sensing—senses charge on both battery banks
• 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
• Senses charging on two battery banks
• LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation
• 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance
• 7/8" (22mm) stud length accepts multiple cable terminals
• Silver alloy contacts provide high reliability for switching live loads
• Label recesses for circuit identification
