Blue Sea ML Series HD Auto Charge Relay 12V with remote switch

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

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
