Blue Sea Solenoid ML500A Automatic Charging Relay 12V - 7622-BSS

The Blue Sea 7622 ML-ACR Automatic Charging Relay with Manual Control is a highly reliable and versatile component for managing the charging and isolation of battery banks in 12V DC systems. Designed for high-output alternators and heavy-duty applications, this 500A magnetic latching (bi-stable) relay ensures seamless operation during both charging and discharging.

The device combines two batteries automatically during charging and isolates them when discharging or starting the engine, while also offering an added layer of safety with its manual control switch. This manual switch allows users to control the relay with or without power and offers a "LOCK OFF" capability for safe servicing. The ML-ACR relay also features dual sensing to monitor both battery banks and supports paralleling for emergency starts.
