Detailed description

Dissenyat per a sistemes elèctrics marins exigents, el tallacor de bateria a distància ML-RBS 7702B-BSS de BLUE SEA és una solució de gestió d’energia per a instal·lacions de 24V CC. Aquest dispositiu ofereix una capacitat d’interrupció en càrrega elevada, amb un corrent continu de 500A, un corrent intermitent de 700A (durant 5 minuts) i un corrent d’arrencada de 1450A (durant 30 segons).

Tecnologia i Característiques Clau

El ML-RBS 7702B-BSS integra una tecnologia de bloqueig magnètic biestable, cosa que significa que no consumeix cap corrent en posició ON o OFF, reduint així el drenatge paràsit. El corrent només es consumeix durant el canvi d’estat (menys de 4A durant 40 ms). Els seus contactes d’aliatge d’argent garanteixen una alta fiabilitat per a la commutació de càrregues actives. A diferència dels solenoides de la sèrie ML sense comandament manual (referència 7701/7703), aquest model 7702B-BSS incorpora un botó de comandament manual que ofereix un nivell addicional de seguretat. Aquesta funció permet una activació o desactivació manual amb o sense alimentació elèctrica, i inclou una capacitat de bloqueig en posició OFF per a operacions de manteniment. El producte està dissenyat amb cargols de coure estañat de 3/8"-16 (M10) per a una conductivitat màxima i una resistència augmentada a la corrosió, assegurant connexions robustes amb un parell màxim de 15.8 N•m (140 in-lb).

Integració i Durabilitat

El tallacor de bateria ML-RBS 7702B-BSS compleix els requisits de protecció contra la inflamació externa ISO 8846 i SAE J1171, i porta el marcatge CE, cosa que el fa adequat per a compartiments de motor de vaixells de gasolina. El seu índex d’estanquitat IP66 el protegeix contra dolls d’aigua forts. El dispositiu suporta una tensió de funcionament dels contactes de 0-64V, oferint versatilitat per a sistemes multitensió, mentre que la seva tensió de control nominal és de 24V CC (rang de 18-32V CC). El ML-RBS 7702B-BSS es posiciona com una solució avançada per a la gestió de bateries de 24V, oferint una alternativa més performant i segura que els interruptors manuals clàssics o els solenoides sense opció de control físic directe.

« Advanced control of 24V high-current circuits with the ML-RBS »

The BLUE SEA ML-RBS 7702B-BSS remote battery switch is a strategic component for high-power 24V marine electrical architectures. Its bistable magnetic latching design is a major advantage, as it eliminates any holding current consumption—a critical point for the autonomy of embedded systems, especially compared to continuously excited solenoids. This feature makes it particularly relevant for vessels equipped with large battery banks or high-energy loads.

The integration of a physical manual override, in addition to the ability to be operated remotely via an SPDT switch (available separately), provides enhanced operational flexibility and safety. This manual function is essential for emergency maneuvers or maintenance procedures, allowing circuits to be isolated even when the control circuit is unpowered. For installation, it is imperative to mount the unit as close as possible to the battery(ies) to minimize the length of heavy-gauge cables (e.g., 2x 4/0 AWG), thereby reducing voltage drops and losses. Control connections can then be routed to the helm or a centralized control panel using smaller-gauge cables.

This model stands out within the ML series due to its 0-64V contact voltage, making it compatible with advanced battery systems or multi-voltage configurations, offering some investment longevity. It is best suited for isolating the main circuit of one or more battery banks, or for switching critical loads such as bow thrusters, windlasses, or high-power inverters, rather than for fast and repetitive switching applications.

Frequently Asked Questions

Need help? Contact us

What is the main function of the ML-RBS 7702B-BSS remote battery switch?

The ML-RBS 7702B-BSS remote battery switch is designed to provide high-current switching under load in 24V DC marine electrical systems. It allows remote control of power management for battery banks, offering the ability to disconnect or connect circuits remotely.

What is the DC current capacity of this battery switch?

This battery switch has a DC current capacity of 500A. It can also handle an intermittent current of 700A for 5 minutes and a starting current of 1450A for 30 seconds when used with 2x 4/0 AWG cables.

Does the 7702B-BSS battery switch have a manual control?

Yes, the 7702B-BSS model is equipped with a manual control button. This feature provides an additional safety level, allowing manual activation or deactivation of the battery switch with or without power supply, and includes a lock function in the OFF position for maintenance.

What types of contacts are used in this battery switch and why?

This battery switch uses silver alloy contacts. These contacts provide high reliability for switching active loads, ensuring durable and stable performance.

What are the dimensions of the connection studs?

The battery switch is equipped with 3/8"-16 (M10) tinned copper studs. These studs are designed for maximum conductivity and increased corrosion resistance.

What is the maximum recommended torque for connection studs?

The maximum recommended torque for connection stud nuts is 15.8 N•m (140 in-lb). It is essential to respect this torque to ensure robust and secure connections.

Is the Blue Sea ML-RBS battery switch waterproof?

Yes, this battery switch has an IP66 waterproof rating. This means it is protected against powerful water jets, making it suitable for marine environments.

What is the weight of this battery switch?

The weight of this battery switch is approximately 0.93 kg (2.05 lb).

Can the battery switch be used in a gasoline engine compartment on a boat?

Yes, the ML-RBS 7702B-BSS battery switch complies with external ignition protection requirements per ISO 8846 and SAE J1171 and is CE marked. It is therefore suitable for installation in gasoline engine compartments on boats.

What is the operating voltage of this battery switch?

This battery switch is designed for 24V DC systems. The nominal control voltage is 24V DC (range 18-32V DC), and the contact voltage can range from 0 to 64V.

Can I use a remote switch to control this battery switch?

Yes, the battery switch can be controlled remotely. It is typically operated by a momentary SPDT (ON)-OFF-(ON) control switch, such as the Contura PN 2145 switch (sold separately).

Is the battery switch compatible with multi-voltage systems?

The battery switch has a contact voltage range of 0–64V DC, making it compatible with nominal 36V DC and 48V DC systems while maintaining a 24V DC control voltage. This makes it suitable for multi-voltage systems such as solar setups or golf carts.

What are the live switching cycle capabilities of the battery switch?

The battery switch can perform 10,000 live switching cycles at 24V and 150A, and 2,000 cycles at 48V and 100A.

Where should I install the ML-RBS battery switch?

It is recommended to install the battery switch as close as possible to the battery bank. To prevent corrosion of the wires and connection terminals, mount it in a dry and protected location. Avoid mounting it directly above ventilated lead-acid batteries to prevent exposure to corrosive gases.

Are the A and B terminals on the battery switch specific to the battery or the charger?

The stud terminals A and B are interchangeable. The battery bank can be connected to either one, and the charger to the other.

What type of wiring is recommended to achieve the 500A DC current capacity?

To achieve the 500A DC current capacity, it is recommended to use two 4/0 AWG cables (2x 120 mm²).

Is a circuit protection required for the wires connected to the battery switch?

If the battery switch is used for loads such as an inverter, a windlass, or a bow thruster, the circuit wires must be protected by a circuit breaker or fuse to comply with ABYC standards. Wires used for engine starting typically do not require circuit protection.

How can I prevent the remote operation of the battery switch?

To prevent remote operation and secure the system for maintenance, you can rotate the manual control knob to the "LOCK OFF" position. A cable gland can be inserted into the hole provided for physical locking.

Which safety certifications and standards does this product comply with?

This battery switch is CE certified and meets external ignition protection requirements per ISO 8846 and SAE J1171 standards. Its waterproof rating is IP66.
