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

Features

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
