Product Details

The Blue Sea Systems 7700 ML-RBS Remote Battery Switch brings push-button convenience to high-amperage battery bank management. This 500-amp magnetic latching switch enables battery switching under load from remote locations or via manual control, eliminating the need to access hard-to-reach battery compartments.

Dual Control Design:

The ML-RBS features both remote and manual operation for maximum flexibility and safety. The included SPST Contura-style remote switch (Blue Sea Systems 2155) mounts easily at the dash or nav station, requiring only light-gauge wire for installation. A built-in manual control lever with lock-out feature ensures you can always control the battery even if remote switch wiring is compromised. The sliding cover on the remote switch prevents accidental switching.

Key Features:

  • 500A continuous rating with 700A intermittent capacity (5 minutes) and 1450A cranking rating
  • Magnetic latching design with no parasitic draw while not actively switching
  • Service lock-out feature prevents accidental current flow during electrical system maintenance
  • 3/8" tin-plated copper studs for maximum conductivity and corrosion resistance
  • Silver alloy contacts provide reliable switching for large loads
  • LED output in switch enables status indication with optional LED panel
  • Label recesses for easy battery bank identification
  • Compatible with Blue Sea MV-ACR for enhanced battery management
  • Ignition protected for safe use in gasoline engine rooms
  • IP66 rated for marine environments

Technical Specifications:

  • Maximum Voltage: 12V DC
  • Continuous Rating: 500A
  • Intermittent Rating: 700A (5 minutes)
  • Cranking Rating: 1450A (10 seconds)
  • Recommended Cable Size: 4/0 AWG
  • Terminal Stud Size: 3/8"
  • Remote Switch Dimensions: 1 13/16"L x 1"W x 1 1/2"D (1/2" above dash)
  • ML-RBS Unit Dimensions: 5 7/16"L x 3 3/4"W x 2"D
  • Mounting: #10 screws
  • Approvals: ISO 8846, SAE J1171, CE marked, IP66 rated

The ML-RBS installation offers two key benefits: it positions switching control where you need it most, and it shortens heavy cable runs by locating the switching mechanism near the batteries. Backed by Blue Sea Systems' lifetime warranty, this remote battery switch provides professional-grade reliability for demanding marine electrical systems.
