    500 Amp magnetic latching (bi-stable) relay automaticallycombines batteries during charging and isolates batterieswhen discharging and when starting engine

    Features
    • Manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing
    • Includes ML-Series Remote Control Contura Switch PN 2146
    • 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
