Rafmagnsskipti með fjarkerfi ML-RBS frá Blue Sea, með handvirkri losunarvirkni - 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 ratings:

Continuous current: 500ADIntermittent current (5 min): 700ADStarting 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 (<13 mA at 25°C) in both ON and OFF positions. Current draw occurs only during state change (approximately 4 A for 40 ms).

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

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

The terminal studs are made of tinned copper and sized at 3/8"-16 (M10). They are 22 mm (7/8") long to accommodate multiple cable lugs. The maximum recommended 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 battery switch should be installed as close as possible to the battery bank. This minimizes voltage drop and optimizes system performance.

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

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

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 features 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).

When switching state (transition 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 integrated manual override.

The 7717-BSS battery switch 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 systems with 24V contact voltage.
