Detailed description

The BEP FH ANL THROUGH PANEL 500A fuse holder (reference 778-ANLTP) is an electrical protection solution designed for marine installations requiring careful and compact integration. Suitable for voltages up to 50 VDC, this fuse holder supports an amperage range of 35 to 500 A, making it an essential component for protecting high-consumption circuits such as inverters, bow thrusters, or main battery banks. Its compact dimensions of 98 x 49 x 36 mm and weight of 298 g facilitate installation in confined spaces.

Through-panel design and optimized connectivity

The distinctive feature of the FH ANL THROUGH PANEL 500A is its through-panel design, allowing a maximum panel penetration of 19 mm (3/4 inch). This design ensures clean and secure mounting through a bulkhead or panel, minimizing cable clutter and providing an aesthetic finish. The connection studs for 10 mm (3/8 inch) cables guarantee optimal conductivity and compatibility with high-cross-section cables, while the fuse mounting studs of 8 mm (5/16 inch) are also compatible with 10 mm (3/8 inch) fuses, offering flexibility in use with ANL or ANN (very fast) fuses.

Positioning in the BEP range and technical comparison

Unlike standard BEP ANL fuse holders, such as the 35-300A model (778-ANL), which is a surface-mount unit with 8 mm studs and a total depth of 54 mm, the FH ANL THROUGH PANEL 500A offers a higher amperage capacity and more discreet integration thanks to its through-panel mounting. Compared to the 35-750A two-stud ANL fuse holder (778-ANL2S), which handles higher currents but has larger dimensions (147 x 49 x 61 mm) and is not designed for through-panel mounting, the 778-ANLTP is the ideal solution for applications requiring both high protection and wall integration. It also differs from class T fuse holders (such as the 225-400A or 450-600A models), which are designed for much higher current interruption capacities (20,000 to 50,000 A) and different applications, highlighting the specific positioning of the 778-ANLTP for medium to high-power DC systems in marine environments.

« ANL through-panel protection: optimized integration »

The BEP FH ANL THROUGH PANEL 500A (778-ANLTP) fuse holder is a technically sound solution for protecting high-current DC circuits in a marine environment. Its through-panel design is a major advantage for integrators and professionals seeking to optimize space and installation cleanliness. With a maximum penetration depth of 19 mm, it significantly reduces visible bulkhead clutter in cockpits or control panels where every millimeter counts.

This model accepts ANL/ANN fuses from 35 to 500 A at 50 VDC, making it suitable for protecting critical systems such as converters, thrusters, or main battery connections. The 10 mm (3/8 inch) stud terminals ensure compatibility with large-gauge cables, providing low resistance and excellent conductivity. BEP’s robust materials are proven in saltwater environments. It stands out from standard ANL fuse holders by its integration capability, offering a more aesthetic and secure alternative for permanent installations. For applications requiring higher interrupt ratings, Class T fuse holders should be considered, but for common ANL applications, this model delivers an excellent balance of performance, integration, and durability.

What is the supported amperage range for this fuse holder?

This fuse holder is designed for ANL fuses with an amperage range from 35 A to 500 A.

What is the maximum voltage this fuse holder can handle?

The maximum voltage this fuse holder can handle is 50 VDC (direct current).

Is this product a standard fuse holder or a specific model?

It is an ANL through-panel fuse holder, meaning it is specifically designed to be mounted through a bulkhead or panel.

Is this fuse holder supplied with a fuse?

No, product 778-ANLTP is a fuse holder. The ANL fuse itself is not included and must be purchased separately.

What is the diameter of the connection studs for the power cables?

The connection studs for the cables have a diameter of 10 mm (3/8 inch).

What is the diameter of the studs on which the fuse is mounted?

The fuse mounting studs have a diameter of 8 mm (5/16 inches).

Which types of ANL fuses are compatible with this fuse holder?

This fuse holder is compatible with ANL fuses whose studs have a diameter of 8 mm (5/16 inch) or 10 mm (3/8 inch).

Can this fuse holder be used with 12 V or 24 V electrical systems?

Yes, the maximum rated voltage of 50 VDC makes this fuse holder compatible with 12 V, 24 V, and other DC systems up to 50 V.
