Blue Sea Systems ML Series Automatic Charging Relay - available in 12V or 24V.

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

Includes the vibration, shock, thermoshock, moisture & salt spray resistant SPDT Remote Control Contura Switch - ON-OFF-ON (2146).

Features: 

  • Magnetic Latching (ML) relay draws very low current in the ON 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 maximise alternator output
  • Manual override knob provides an added level of safety allowing control with or without power and offering LOCKED OFF capability for servicing
  • Senses charging on two battery banks
  • LED output to remotely indicate switch state – requires optional LED or Remote Control Contura Switch with integrated LED (included in retail package)
  • 3/8″-16 tin-plated copper studs for maximum conductivity and corrosion resistance
