Description

500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine.
There are many dual battery relays on the market. There are not many that can handle winch loads.
The Blue Sea ML ACR gives you the best of all worlds. Combine batteries on demand, in the cabin, using the 2146 switch (included). Select fully automatic battery isolation to ensure starting battery remains charged whilst using the AUX battery, or switch the relay completely off to maintain separation.

If for some reason the switch does not work, this relay features a mechanical override, allowing complete manual control over the relay.

  • Manual override knob provides jump start capability plus  an added level of safety allowing control with or without power and offering LOCKED OFF capablility for servicing
  • LED output to remotely indicate switch state -requires optional LED
  • 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
  • Waterproof – rated IP66 from water projected in powerful jets
