« Technical analysis: Blue Sea ML 12V DC solenoid, bi-stable power switch »

The Blue Sea ML 12V DC solenoid (PN 7701) is an essential power switching solution for marine electrical installations requiring remote load management without direct manual intervention on the main device. Unlike the "remote battery switch" (PN 7700) version, this model focuses solely on the solenoid function, making it particularly relevant for high-power circuits such as engine starters, winches, or bow thrusters, where local manual disconnection is not an operational priority.

Its distinct advantage lies in its magnetic latching bi-stable design. This technology allows the solenoid to maintain its position (open or closed) without continuous current draw, which is crucial for optimizing onboard energy consumption, especially on sailboats or cruising boats where every milliamp matters. The integration of a magnetic latching coil significantly reduces the load on the control system, extending the lifespan of control switches and minimizing thermal losses. The ability to handle contact voltages up to 64V DC while being controlled by a 12V circuit offers interesting flexibility for more complex electrical architectures, potentially including hybrid systems or battery banks in series for higher voltages.

Installation must be designed to leverage its IP66 robustness and flame-resistant protection by placing it in close proximity to the battery banks it serves, while avoiding areas of corrosive gas accumulation. Cable sizing is critical, with a recommendation of 2x 4/0 AWG to achieve its maximum performance. The absence of an integrated manual control implies total dependence on the remote control switch (such as the included Contura 2145), necessitating careful planning of its location on the dashboard for easy access when needed.
