Remote-controlled battery switch ML-RBS with manual override and automatic tripping - 24 V

The BLUE SEA ML-RBS 7717-BSS remote battery switch is designed to carry and switch high currents under load, providing reliable management of marine electrical systems. It allows remote connection or disconnection of one or more batteries from a circuit.

This battery switch model, the BLUE SEA ML-RBS 7717-BSS, is specifically designed to operate with 24V DC electrical systems. Its contact and control voltage range is 18-32V DC.

For connections with two 4/0 AWG cables (2x 120 mm²), the 7717-BSS battery switch has the following capacities:

Continuous current: 500ADC
Intermittent current (5 min): 700ADC
Starting current (30 sec): 1450A

No, the ML-RBS 7717-BSS uses a magnetic latching (bi-stable) design. This means it only draws a very low continuous current (<13mA at 25°C) in both ON and OFF positions. Current draw occurs only during state changes (approximately 4A for 40 ms).

The 7717-BSS battery switch is equipped with silver-alloy contacts. These contacts provide high reliability for switching loads under voltage, supporting 150A at 24V DC over 10,000 cycles.

Yes, model 7717-BSS includes a manual override with a "LOCK OFF" function. This function allows manual disconnection of the battery bank for electrical system maintenance, providing independent control of power even without current.

The terminal studs are made of tinned copper in size 3/8"-16 (M10). They measure 22 mm (7/8") in length to accommodate multiple cable lugs. The recommended maximum torque for the terminal studs is 140 in-lb (15.8 N•m).

The ML-RBS 7717-BSS is rated IP66, meaning it is protected against powerful water jets. Additionally, it meets the external ignition protection requirements of ISO 8846 and SAE J1171.

The BLUE SEA ML-RBS 7717-BSS battery switch has a mechanical endurance of 100,000 cycles.

The ML-RBS remote battery switch should be installed as close as possible to the battery bank. This minimizes voltage drop and optimizes system performance.

The maximum recommended torque for 3/8"-16 (M10) terminal studs is 140 in-lb (15.8 N•m). It is critical to respect this torque to ensure a secure connection and optimal conductivity.

Yes, all unused control wires must be carefully insulated from each other and from accidental contact. The use of heat-shrink tubing or insulating tape is recommended to prevent malfunctions caused by external contact or short circuits.

Yes, retail units of the ML-RBS 7717-BSS include a PN 2155 remote control switch. It is an SPDT (Single Pole Double Throw) ON-ON type switch.

The 7717-BSS battery switch has an LED output that can be connected to an LED or a Contura remote control switch with integrated LED (such as PN 2155 included in retail versions). This LED remotely indicates the switch's status (ON/OFF).

During state change (switching from ON to OFF or vice versa), the ML-RBS 7717-BSS battery switch consumes approximately 4A for 40 ms at 25°C and nominal voltage.

The required mounting hole for the ML-RBS 7717-BSS battery switch measures 0.83" x 1.45" (21.08 mm x 36.83 mm).

Yes, model 7717-BSS is comparable to the 7713 from the same ML-RBS series, which is the 12V version. It differs from solenoids 7718 and 7719 by the integration of a manual override.

The 7717-BSS battery isolator is equipped with label cutouts, allowing for clear and easy identification of connected circuits. This helps organize and maintain clarity in your electrical system.

No, the ML-RBS 7717-BSS is specifically designed for 24V DC systems. Its control voltage is 18-32V DC and its contact voltage is also 18-32V DC. It is not designed for 12V control voltage with 24V contact voltage systems.
