Detailed description

Designed for marine and embedded electrical systems, the BLUE SEA e-Series Selector 3-Position Battery Switch with AFD (part number 11001) provides reliable management of two battery banks. This 3-position switch (battery 1, battery 2, off) is specifically intended for high-power applications requiring proven reliability and low heat generation, such as boats equipped with inboard gasoline or diesel engines.

Performance and Technical Specifications

Model 11001 delivers electrical performance with a 1,200 A cranking capacity for 30 seconds. It supports an intermittent current of 600 A (5 minutes) and a continuous current of 350 A at 32 V DC. Its tinned copper 3/8"-16 (M10) stud terminals ensure maximum conductivity and corrosion resistance, with a length of 22.22 mm to accept multiple cable lugs. The recommended tightening torque is 15.82 N·m (140 in-lb). To achieve its rated values, use of 4/0 AWG (120 mm²) cables is required.

Advanced Features and Compliance

A distinctive feature of the 11001 is its Alternator Field Disconnect (AFD) function, which protects the alternator diodes in case of engine-running switch disconnection by reducing the alternator output to zero. This protection is critical for the longevity of the charging system. The switch is also ignition-protected, meeting SAE J1171, UL 1500, and ISO 8846 requirements, making it safe for installation on gasoline-powered boats. It complies with ABYC battery switch requirements and is UL 1107 listed. Its housing allows surface or rear-panel mounting, offering installation flexibility. Unlike the e-Series Selector 4-Position or Dual Circuit Plus models, this switch does not feature "make-before-break" operation when switching between banks 1 and 2, requiring the "OFF" position to be selected before changing banks.

« Technical analysis: BLUE SEA e-Series Selector 3 Position battery switch with AFD »

The BLUE SEA e-Series Selector 3 Position battery switch with AFD (model 11001-BSS) is a relevant solution for vessels equipped with two battery banks, typically a starter bank and a house bank. Its primary function is to isolate these banks, allowing you to select power from battery 1 or battery 2, or cut all power in the OFF position. This is fundamental for electrical safety on board and energy management.

The key added value of this model lies in its Alternator Field Disconnect (AFD) system. This feature is crucial for preventing irreversible damage to the alternator diodes if the switch is toggled to OFF while the engine is running. Many competing switches or basic models in Blue Sea’s m-Series lack this protection, requiring manual precautions or additional circuits. The integration of AFD simplifies installation and enhances the reliability of the charging system.

For installation, it must be mounted near the batteries and the specified torque values (15.82 N·m) for 3/8"-16 (M10) studs must be respected; these studs are tin-plated copper for improved durability in marine environments. Using 4/0 AWG (120 mm²) cables is recommended to ensure nominal performance. It is critical to note that, unlike "make-before-break" switches (such as certain Selector 4 Position or Dual Circuit Plus e-Series models), switching from the "Battery 1" position to "Battery 2" (or vice versa) must be done by passing through the "OFF" position to avoid any uncontrolled interruption of charge or discharge. This is a limitation to consider for systems that cannot tolerate any momentary power interruption. This model is ideal for owners seeking simple and secure management of two batteries with integrated alternator protection, without the complexity or cost of a four-position switch or a Dual Circuit Plus if they do not require the direct combination function via the switch.

Frequently Asked Questions

Need help? Contact us

What are the main functions of the Blue Sea e-Series Selector 3-position battery switch with AFD?

The switch is designed to manage two battery banks. It allows isolation of starting and service circuits, and offers the option to combine both battery banks for emergency starting. It has three positions: battery 1, battery 2, and off (OFF).

What does the 'AFD' (Alternator Field Disconnect) function mean on this switch?

The AFD (Alternator Field Disconnect) function is a distinctive feature that protects the alternator's diodes. If the switch is turned off while the engine is running, it reduces the alternator output to zero, which is critical for the longevity of the charging system.

What is the DC current capacity of this battery switch?

This switch has a DC current capacity of 350 amperes at 32 V DC.

What is its cranking rating?

The cranking rating of this switch is 1 200 amperes for 30 seconds.

Is the switch ignition-protected for use on gasoline-powered boats?

Yes, this switch is ignition-protected. It meets the requirements of SAE J1171, UL 1500, and ISO 8846 standards, making it safe for installation on boats with gasoline engines.
