Dvigubas grandiklis Plus™ e-Series

The BLUE SEA e-Series Dual Circuit Plus™ battery switch (model 5511e) is designed to robustly and securely manage two separate battery banks (for example, a starter bank and a house bank) in marine electrical systems. It allows you to isolate these circuits, use them independently, or combine them for emergency starting. It is ideal for applications requiring high power, consistent reliability, and minimal heat generation.

The 5511e battery switch provides a DC current rating of 350 amperes per circuit. This specification ensures stable and reliable power supply for your electrical systems.

This battery switch has an intermittent current capacity of 525 amperes per circuit for 5 minutes (per UL 1107 standard). For starting, it can handle a current of 700 amperes per circuit for 30 seconds.

The BLUE SEA e-Series Dual Circuit Plus™ 5511e battery switch is designed to operate with a maximum voltage of 32V DC (direct current).

Model 5511e is specifically sized for inboard gasoline and diesel engine electrical systems. It is designed for applications requiring high power and reliable battery management.

The 5511e battery isolator switch has three main positions:

OFF: Completely isolates the batteries.ON: Isolates and allows separate use of the two battery banks.COMBINE BATTERIES: Connects the two battery banks together, typically for emergency starts.

The 'Make-Before-Break' function (connect before disconnect) allows switching between battery banks without interrupting the electrical supply to connected circuits. This is an essential feature to maintain power continuity for sensitive onboard equipment.

Yes, the 5511e battery switch is protected against ignition. It meets external ignition protection requirements per UL 1500 and SAE J1171 standards.

The terminal studs are made of tinned copper for maximum conductivity and excellent corrosion resistance. They are sized 3/8"-16 (M10) and have a length of 22.22 mm (7/8") to accommodate multiple cable lugs.

The recommended torque for battery cable terminals is 15.82 N·m (140 in-lb). It is critical to adhere to this value to ensure secure and reliable connections and minimize the risk of overheating.

The stud terminals are designed to accept multiple cable lugs, including cables up to 4/0 AWG (120 mm²) per terminal, to ensure secure and reliable connections.

The battery switch must be installed in an easily accessible location close to the batteries. This makes it easier to operate and maintain.

The casing design allows for surface mounting or rear-panel mounting. It is also compatible with most PERKO and Guest battery switch mounting hole patterns.

Yes, it is mandatory to disconnect the battery's positive terminal before installing the battery switch for safety reasons.

The 5511e battery switch has a width of 98 mm (3.85") and a height of 98 mm (3.85"). Mounting centers are spaced 76 mm (3.00") apart.

Yes, the 5511e battery switch complies with the American Boat and Yacht Council (ABYC) requirements for battery switches. It is also UL listed (UL 1107) for electrical power switches.

Yes, the Dual Circuit Plus™ battery isolator is designed to be used with an automatic charging relay (ACR). This combination allows simultaneous and efficient charging of two battery banks from the engine alternator while isolating the batteries during engine start and when charging is inactive.

The 5511e battery switch has an IP66 protection rating, meaning it is protected against powerful water jets. This makes it suitable for marine environments where water exposure is common.

The 5511e is part of the e-Series, which offers a continuous capacity of 350A and is designed for inboard gasoline and diesel engines. It differs from the m-Series (300A continuous, for small outboard and inboard gasoline/diesel engines) and the HD-Series (500-600A continuous, for large diesel engines).

Using cables with a smaller gauge than recommended (4/0 AWG or 120 mm²) will reduce the current-carrying capacity of the battery switch. This can lead to cable overheating and suboptimal electrical performance of the system.
