Blue Sea 7703 – ML Solenoid 500A 24V DC Magnetic Latching with Remote Contura Switch 2145
The Blue Sea 7703 ML Solenoid is a 24V DC magnetic latching (bi-stable) solenoid designed for high-current battery circuits where manual control is not required. It is intended for engine, inverter, house loads, and emergency battery combine applications and supports switching under load.
The magnetic latching design draws no current in the ON or OFF state and only consumes power when changing state. The unit uses silver alloy contacts for reliable live-load switching and tin-plated copper studs for conductivity and corrosion resistance. A remote control Contura switch is included.
