Blue Sea Systems 7622BSS ML Series 12V Automatic Charging Relay with Manual Override

The Blue Sea Systems 7622BSS ML Series Automatic Charging Relay is a 500 amp magnetic latching (bi-stable) relay designed to automatically combine batteries during charging and isolate them when discharging or starting your engine. This intelligent relay ensures optimal battery management for dual-battery systems in marine, RV, and other 12V DC applications.

Key Features:

• Magnetic latching (ML) relay technology draws minimal current in the ON state for maximum efficiency
• Senses charging voltage on two separate battery banks for automatic operation
• Start Isolation (SI) feature can be configured for temporary isolation of house loads from engine circuits
• LED output provides remote indication of relay switch state
• 3/8"-16 tin-plated copper studs deliver maximum conductivity and corrosion resistance
• 7/8" stud length accommodates multiple cable terminals for flexible installation
• One-piece stainless steel flange nuts ensure safe and secure connections
• Silver alloy contacts provide high reliability for live switching applications
• Label recesses included for easy circuit identification
• Includes Remote Control Contura Switch (Blue Sea Part #2146) for manual override capability

This automatic charging relay is ideal for managing dual-battery systems where you need to charge both batteries simultaneously while maintaining isolation during discharge to prevent draining your starting battery. The manual override switch provides flexibility when you need direct control of battery combination.
