The Blue Sea Systems ML-RBS remote battery switch offers a reliable solution for managing high-current connections with advanced safety features. Designed for 24V DC systems, this switch provides a manual override knob that allows for safe control during maintenance or emergencies, including a LOCKED OFF position to prevent accidental operation. An optional LED indicator (not included) can be connected to remotely monitor the switch state, enhancing system visibility. Constructed with 3/8"-16 tin-plated copper studs, the switch ensures maximum conductivity and resistance to corrosion, making it suitable for demanding marine and industrial environments. The stud length of 7/8" (22mm) accommodates multiple cable terminals, simplifying installation and wiring.

Built with silver alloy contacts, the ML-RBS guarantees high reliability for switching live loads, supporting continuous ratings of up to 500 amps and intermittent ratings of 700 amps for five minutes. Its auto-releasing coil feature allows for quick disengagement, reducing stress on the circuit during switching operations. The switch's control circuit employs tinned wire connections, with a voltage range of 20.2 to 32.9V DC, making it compatible with various power systems. It features a manual control option, mounted easily using #10 hardware, and operates efficiently within temperature ranges from -10°C to 50°C. The switch's robust design includes a mechanical endurance of 100,000 cycles, ensuring longevity and durability.

Additional features include the ability to handle live current switching up to 300A at 12V DC for 10,000 cycles, a master control switch capability, and a terminal ring diameter clearance of approximately 1.18 inches. The terminal stud size is 3/8-16 (M10), with a torque requirement of 140 in-lb (15.82 Nm). Weighing around 1.75 pounds, the switch is suitable for various applications where high-current management and safety are priorities. Note that this product may contain chemicals known to cause reproductive harm, and a detailed warning is available on the manufacturer’s site.

For detailed installation instructions and safety information, please refer to the owner’s manual available online. The Blue Sea ML-RBS remote battery switch is an essential component for reliable power management in marine, RV, or industrial systems, combining safety, durability, and ease of use in one unit.
