Product Details

The Blue Sea Systems 7718100-BSS ML-Series Remote Battery Switch is a high-capacity switching solution designed for marine and mobile applications requiring reliable power management. This 12-volt DC solenoid provides robust 500-amp intermittent switching capability, making it ideal for battery isolation, emergency parallel switching, and remote battery management systems.

Key Features:

  • Heavy-duty ML-Series solenoid rated for 12V DC systems with 500-amp intermittent capacity
  • Includes SPDT (Single Pole Double Throw) Remote Control Contura switch for convenient remote operation
  • ON-ON switch configuration allows switching between two circuits or battery banks
  • Durable black housing designed for harsh marine and mobile environments
  • DTM (Deutsch-style Terminal) connections for secure, waterproof wiring
  • Compact design allows installation in tight engine rooms and electrical compartments
  • Low coil current draw minimizes parasitic battery drain

This complete kit provides everything needed for remote battery switching applications, eliminating the need for heavy gauge cable runs to a manual switch location. The included Contura switch offers Blue Sea Systems' signature quality and can be panel-mounted in any convenient location, while the ML-Series solenoid handles the heavy switching duty near the batteries. Ideal for sailboats, powerboats, RVs, and commercial vehicles requiring reliable battery management.

Only website that had the specific tire I required. Thank you. Cheers.

Y&#039;all the only ones to have what I needed. Thus far

great price

Everything arrived as expected.

Cheapest price for the lift kit I could find.

The way it was described it come with everything you needed and it took over a week to get the product to find out it did not come with the lower unit so now it's going to take another 5 to 10 days to get the rest of the product it should've come with everything it's not a replacement air conditioner
