Wyłącznik baterii zdalny ML-RBS z ręcznym sterowaniem - 12 V DC 500 A

The BLUE SEA ML-RBS (model 7700) remote battery switch is a magnetic battery switch designed for managing high-current 12V DC circuits. It reliably isolates battery banks or connects heavy loads, with remote or manual switching capability.

The magnetic latching (bi-stable) technology means the battery switch consumes no current in either ON or OFF state. It only draws current (less than 7A for 20 ms) during state changes, optimizing power consumption compared to traditional solenoids that require continuous holding current.

This battery switch has a continuous current rating of 500 amperes (500A DC). It can also handle up to 700A intermittently (for 5 minutes) and 1450A in peak (for 30 seconds).

Yes, the ML-RBS battery switch is rated IP66. This means it is protected against powerful water jets and dust ingress, making it suitable for marine environments.

The battery switch is equipped with silver-alloy contacts. These contacts provide high reliability for switching loads under load.

This battery switch is designed for long service life. It supports 10,000 switching cycles under 12V/300A load and 100,000 mechanical switching cycles.

The ML-RBS battery isolator meets external ignition protection requirements per ISO 8846 and SAE J1171. It is also CE marked.

The manual override button provides an additional safety level. It allows manual ON/OFF control with or without power and includes a "LOCK OFF" function to secure the electrical system during maintenance.

Yes, the battery isolator has a remote LED output that can indicate its state (ON/OFF) from a distance. The LED indicator itself is sold separately.

The dimensions of the battery switch are as follows:

Length: 138.94 mmWidth: 95.25 mmHeight (including terminals): 76.20 mmInstallation depth: 48.26 mm

The battery switch should be installed as close as possible to the battery bank. Choose a dry, protected location to prevent corrosion of cables and terminals. Avoid mounting it directly above vented lead-acid batteries to avoid exposure to corrosive gases.

The main connection terminals are 3/8"-16 (M10) tinned copper studs. They are designed for maximum conductivity and corrosion resistance.

The maximum torque for the nuts on the heavy-duty terminal studs is 15.8 N•m (140 in-lb).

Yes, terminals A and B are interchangeable. The load can be connected to terminal A or B, and the battery bank to the other terminal.

Yes, it is imperative to disconnect all negative battery connections before starting the installation for safety reasons.

To activate the "LOCK OFF" function, turn the manual control knob to the right until it reaches the "LOCK OFF" position. You can then pass a cable tie (not included) through the provided hole to secure the battery switch in this position and prevent any remote operation.

The ML-RBS battery switch (model 7700) requires a nominal control voltage of 12V DC, specifically between 9V and 16V DC, for its remote operation.

Yes, it is designed for high-current applications and supports large cross-section cables. To reach its continuous capacity of 500A, it is recommended to use two 4/0 AWG cables (2x 120 mm²).
