Pojistková objímka ANL 35–300 A s krytem

An ANL fuse holder is an electrical component designed to accommodate ANL-type fuses. It is used to protect high-current electrical circuits from overcurrents and short circuits by interrupting the current flow if it exceeds a safe threshold. This model is particularly suited for marine applications for currents ranging from 35 to 300 amperes.

This fuse holder is designed to work with ANL fuses rated from 35 to 300 amperes. It is essential to select the appropriate ANL fuse based on the load and wiring of your circuit for optimal protection.

ANL fuses are preferred for protecting high-current circuits in marine systems, such as main battery lines, inverters, or bow thrusters. They can handle high currents and provide high breaking capacity in case of short circuits, ensuring robust and reliable protection for applications requiring fast and safe interruption of high currents.

No, this fuse holder is sold without a fuse. ANL fuses from 35 to 300 A compatible with this unit must be purchased separately, allowing you to select the exact rating required for your specific application.

This fuse holder is compatible with 12V, 24V, and 48V DC electrical systems, making it versatile for a wide range of marine applications.

The integrated insulating cover has several essential functions:

It protects the fuse holder’s electrical connections from water splashes and dust. It prevents accidental contact with live terminals, thereby increasing safety on board.

Yes, Blue Sea Systems products are specifically designed for the marine environment. This fuse holder is made with robust, corrosion-resistant materials, such as tinned copper terminals and a durable plastic body, to withstand the harsh conditions encountered at sea.

This fuse holder is exclusively compatible with ANL-type fuses. It cannot be used with ATO/ATC, MIDI, or MAXI fuses.

This fuse holder is designed for easy installation on a panel or bulkhead. It must be securely fastened to a flat surface using appropriate screws. Ensure the chosen location is dry, well-ventilated, and easily accessible for fuse maintenance and replacement.

ANL fuses, used with this fuse holder, are known for their high breaking capacity, meaning they can safely interrupt very high short-circuit currents. Unlike ATO/ATC fuses for low currents or MIDI/MAXI fuses for intermediate currents, ANL fuses are optimal for power circuits where hundreds of amps may flow.

Yes, absolutely. This ANL fuse holder is ideal for protecting inverters, bow thrusters, and main battery lines, which are typical applications requiring protection against high currents in a marine system.

To replace a fuse:

Ensure the circuit is powered off for your safety.
Remove the insulating cover.
Unscrew the terminal nuts to release the old fuse.
Insert the new ANL fuse of the correct rating.
Tighten the nuts firmly to ensure a good electrical connection.
Replace the insulating cover.

Yes, it can be installed in an engine compartment, provided the location is protected from direct water spray, excessive corrosive fumes, and has adequate ventilation to prevent heat buildup. The cover provides additional protection against the elements.

Yes, its design is intended to accommodate large-section cables, which is essential for the high-current applications (35-300 A) it is designed to protect. The terminals are robust and allow for reliable and secure connections.

Although exact dimensions are not provided in the textual description, the product includes a technical diagram (reference 02 - Technical Detail) featuring a dimensioned drawing. It is recommended to consult this diagram for precise measurements before installation.

To connect the cables, you will generally need basic tools such as a wrench or socket to tighten the terminal nuts. If your cables are not already fitted with terminals, a crimping tool will be required to prepare them properly. Ensure all connections are clean and securely tightened to avoid hot spots and guarantee optimal conductivity.

No, a fuse holder is installed on a single circuit. Although it is compatible with 12V, 24V, or 48V systems, it cannot be used to protect multiple circuits operating at different voltages simultaneously. Each circuit must have its own protection matched to its voltage and current rating.

For a secure connection:

Use cable lugs of the correct size, properly crimped or soldered onto the cables. Ensure the contact surfaces of the lugs and fuse holder terminals are clean and free of corrosion. Tighten the cable mounting nuts firmly to guarantee optimal electrical contact and prevent loosening due to vibrations.

The ANL fuse holder is designed for very high currents (35-300 A) and provides high breaking capacity, making it ideal for high-power applications such as main battery lines. MIDI and MAXI fuse holders handle intermediate currents, typically up to around 100-150 A, and are used for distribution circuits or medium-power equipment.
