Overview

The Blue Sea Systems 7701-BSS is a 12V DC high-amperage solenoid designed for remote battery switching. It features a 500 Ampere continuous rating suitable for engine, inverter, and house loads, as well as emergency battery combining.

This magnetic latching (bi-stable) solenoid draws no current in its ON or OFF state, only consuming power when changing states. It is equipped with silver alloy contacts for reliability and 3/8"-16 tin-plated copper studs for conductivity and corrosion resistance. The studs offer a 7/8" (22mm) length to accommodate multiple cable terminals.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
