AJAKUUL - BLUE SEA ML 12 V DTM/ATM solenoid

The BLUE SEA ML 12V DTM/ATM solenoid (PN 7718100B-BSS) is a device designed for remote power management in marine electrical systems and specialized vehicles. It enables switching of high currents and is particularly suited to installations where direct manual control is not required, providing a remote switching solution for 12V DC applications.

The main characteristic of the magnetic locking (ML) system is its very low continuous current consumption. In ON or OFF state, the solenoid consumes less than 13mA at 25°C and nominal voltage, which is crucial for preserving battery charge over the long term.

This solenoid has a DC current capacity of 500 amperes, provided appropriate wire sizes are used, such as two 4/0 AWG cables (2x 120 mm²).

The BLUE SEA ML 12V DTM/ATM solenoid can handle intermittent currents of 700 amperes for 5 minutes and DC starting currents of 1450 amperes for 30 seconds when wired with 2x 4/0 AWG (2x 120 mm²) cables.

Yes, the contacts are made from silver alloy for high reliability when switching live loads. They are rated for 10,000 switching cycles under load (300A at 12V DC) and have a mechanical endurance of 100,000 cycles.

The connection studs are made of tinned copper, size 3/8"-16 (M10). Tinned copper ensures maximum conductivity and excellent corrosion resistance, essential in marine environments.

Yes, this solenoid is rated IP66. This means it is fully protected against dust and powerful water jets, making it suitable for harsh marine environments.

Yes, the BLUE SEA ML 12V DTM/ATM solenoid is compliant with external ignition protection requirements per ISO 8846 and SAE J1171. It is also CE marked, attesting to its compliance with European standards.

The solenoid has an LED output that can be used to remotely indicate the switch status (ON or OFF). This feature allows you to check the solenoid’s status without having to inspect it visually.

No, the BLUE SEA ML 12V DTM/ATM solenoid (PN 7718100B-BSS) is a solenoid model without manual backup control. It is designed for fully remote management, unlike other remote battery switches in the ML series that may include this feature.

The maximum voltage this solenoid’s contact circuit can handle is 16V DC.

The solenoid should be installed as close as possible to the battery. This proximity helps minimize voltage drop and optimize the performance of the electrical system.

To operate this solenoid, install a single-pole double-throw (SPDT) or single-pole single-throw (SPST) control switch in a convenient location, near other electrical controls or the cockpit, for quick access in an emergency.

The control circuit is connected via a Deutsch DTM Series DTM 06-6S connector. This type of connector simplifies integration into existing systems.

Recommended wire sizes vary depending on current:

For 1 000A (30 sec), 400A (5 min) and 225A (continuous): 2/0 AWG (70 mm²)

For 1 100A (30 sec), 400A (5 min) and 300A (continuous): 4/0 AWG (120 mm²)

For 1 450A (30 sec), 700A (5 min) and 500A (continuous): 2x 4/0 AWG (2x 120 mm²)

Before starting the installation, it is imperative to disconnect all negative battery connections to prevent any risk of short-circuit or electric shock.

All unused control wires must be carefully isolated from each other and from any accidental contact. It is recommended to use heat-shrink tubing or insulating tape. External contact or a short circuit between control wires can cause malfunction.

No, this solenoid model (PN 7718100B-BSS) is specifically designed for 12V DC electrical systems. For 24V DC systems, you would need to use a model from the ML series designed for this voltage.

The solenoid uses a Deutsch DTM Series DTM 06-6S connector. The required coupling parts for the harness are:

Receptacle shell: DTM-04-6P
Lock: WM-6P
Terminal pins: 1060-20-0122
Sealing plugs: 0413-204-2005
