Blue Sea Systems ML-Series Automatic Charging Relays

Blue Sea Systems ML-Series Automatic Charging Relays offer 500A magnetic latching (bi-stable) relays that automatically combine batteries during charging and isolates batteries when discharging and starting engine. A 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 maximize 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. 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance. 7/8" (22mm) stud length accepts multiple cable terminals. One-piece stainless flange nuts ensure safe and secure connections. Label recesses for circuit identification. Silver alloy contacts provide high reliability for live switching.
