Blue Sea Systems 7713BSS ML-RBS Remote Battery Solenoid Switch 12V 500A with Manual Control

The Blue Sea Systems 7713BSS is a high-performance ML-Series remote battery solenoid switch designed for marine applications requiring reliable 500-amp switching capability. This magnetic latching solenoid features an innovative auto-release function with manual override control, making it ideal for inboard gasoline or diesel engines, inverters, house loads, and emergency battery combining systems.

Key Features:

• 500-amp continuous rating (700A intermittent for 5 minutes) with 2,500A cranking capacity for 10 seconds
• Manual override knob provides added safety, allowing control with or without power and offering locked-off capability for servicing
• Magnetic latching technology draws no current in ON or OFF state—only draws current when changing state
• Silver alloy contacts provide high reliability for switching live loads up to 300A at 12V DC
• 3/8"-16 tin-plated copper studs with 7/8" stud length accept multiple 4/0 AWG cable terminals for maximum conductivity
• Includes SPDT Contura remote switch for convenient control from multiple locations
• IP66 water resistance rating—dust tight and able to withstand water from heavy seas
• SAE J1171 ignition protected, UL rated, and CE marked for marine safety compliance
• Operating temperature range: -10°C to 50°C
• 100,000 cycle mechanical endurance for long-lasting performance

This switch reduces the need for long runs of heavy battery cables by activating with low currents through small control wires. Label recesses allow for easy circuit identification, and the optional LED output provides remote switch state indication. Perfect for applications where both remote control and manual backup are required.
