Kaugjuhtimisega 12 V akukaitselüliti ML-RBS

The ML-RBS 12V battery switch is designed to manage power for marine systems. It allows remote and manual switching of high currents under load, ensuring reliable connection or disconnection of battery banks.

The term "magnetic latching" (also called bistable) means the switch only draws current for the 20 milliseconds required to change state (ON or OFF). Once the state is set, it consumes virtually no current, ensuring excellent energy efficiency.

The ML-RBS 12V has a continuous rating of 500A DC and an intermittent rating of 700A DC for 5 minutes. Its cranking capacity is 1450A DC for 30 seconds when used with two 4/0 AWG cables (2x 120 mm²).

Yes, the ML-RBS is equipped with a manual control button that allows you to turn the switch on or off with or without electrical power. It also features a "LOCK OFF" function to secure the system during maintenance.

This battery switch uses silver alloy contacts. These contacts are designed to provide high reliability when switching loads under load, supporting 10,000 cycles at 300A under 12V.

The battery switch is equipped with 3/8"-16 tinned copper studs. These terminals are designed for maximum conductivity and excellent corrosion resistance in marine environments.

Yes, the switch has an LED output to remotely indicate its state (ON or OFF). This function requires an optional LED or a Contura remote control switch with built-in LED, which is included in the retail packaging.

The maximum recommended torque for terminal studs is 15.8 N•m (140 in-lb). It is critical to adhere to this specification to ensure a secure connection and prevent damage to the terminals.

Yes, the ML-RBS is IP66 certified, meaning it is protected against powerful water jets. It also meets external ignition protection requirements per ISO 8846 and SAE J1171, making it safe for marine environments.

The ML-RBS is rated for 100,000 mechanical switching cycles. For live switching (under load), it supports 10,000 cycles at 12V, 300A; 10,000 cycles at 24V, 150A; and 2,000 cycles at 48V, 100A.

The included Contura remote control switch is designed to operate within a temperature range from -40°C (-40°F) to 85°C (185°F).

The ML-RBS battery switch should be installed as close as possible to the battery banks. To prevent corrosion of wires and terminals, mount it in a dry, protected location. Avoid mounting it directly above ventilated lead-acid batteries to prevent exposure to corrosive gases.

Terminals A and B are interchangeable. Connect the battery bank to one terminal and the load to the other. It is crucial to select the appropriate wire gauge based on the current to ensure the safety and performance of your system.

Yes, the ML-RBS is supplied with a Contura remote control switch (model 2145). This momentary SPDT (ON)-OFF-(ON) switch allows remote control of the battery isolator from a convenient location.

The ML-RBS is supplied with a Deutsch DTM connector. Please note that the mating half of the connector is not included but is required for the control circuit installation.

Before starting the installation, it is imperative to disconnect all negative battery connections. All unused control wires must be carefully isolated from each other and from any accidental contact using heat-shrink tubing or insulating tape to prevent malfunctions.

To achieve the continuous capacity of 500A and the starting capacity of 1450A, it is recommended to use two 4/0 AWG cables (2x 120 mm²). For lower currents, other wire sizes are possible, such as 2/0 AWG (70 mm²) for 225A continuous or 4/0 AWG (120 mm²) for 300A continuous.

The ML-RBS is compatible with contact voltage systems ranging from 0 to 64V DC. However, its nominal control voltage is 12V DC, requiring a control voltage of 9 to 16V DC for operation.

Yes, the ML-RBS can be used to combine or isolate battery banks. Blue Sea Systems also offers a paralleling bus (reference 9160) to facilitate the coupling of multiple ML-RBS battery switches or automatic charging relays, enabling flexible power management.
