Blue Sea Systems 7713 ML-RBS Remote Battery Switch 12V 500A Auto-Release

The Blue Sea Systems 7713 ML-RBS Remote Battery Switch combines the convenience of dash-mounted battery management with the reliability of manual control backup. Designed for 12V marine and RV electrical systems, this heavy-duty switch allows you to control large battery banks from a remote location while keeping the high-current switching mechanism close to the batteries to minimize cable runs.

Key Features:

• 500A continuous rating with 1450A cranking capacity handles large battery banks
• Includes Contura-style SPDT remote switch (Blue Sea 2155) for dash mounting
• Auto-release coil function ideal for relay-controlled battery protection systems
• Manual control lever with service lock-out for safe electrical system maintenance
• Compatible with SPST or SPDT switches for normally open relay applications
