Remote battery switch ML-RBS with manual control - 24 V DC 500 A

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.

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

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 electrical power, and includes a lock-in-OFF position for maintenance.

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

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

The maximum recommended torque for the nuts on connecting studs is 15.8 N•m (140 in-lb). It is important to respect this torque to ensure robust and secure connections.

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

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

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

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.

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).

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

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

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.

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

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

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 generally do not require circuit protection.

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.

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