Vžigalo AMI/MIDI - 50 A (2 komada)

An AMI/MIDI fuse is a compact, high-performance fuse type designed to protect electrical circuits from overcurrents and short circuits. It is particularly suited for marine applications and electrical systems where reliable protection is critical. It acts as an intentional weak link in the circuit, melting to interrupt current flow in the event of an overload, thereby protecting equipment and wiring.

These fuses have a nominal rating of 50 amperes (50 A). This means they are designed to handle continuous current up to 50 A and will blow (melt) if the current exceeds this value for a given period, thereby protecting the circuit.

This pack contains two (2) fuses. This gives you an immediate spare part on board or for another application.

These fuses are manufactured by BLUE SEA Systems, a brand known for its high-quality electrical products designed for marine environments.

The IP66 ingress protection rating means these fuses are fully protected against dust (first digit '6') and against powerful water jets from any direction (second digit '6'). This feature is critical for use in damp or exposed marine environments, such as engine compartments or boat decks.

Yes, these fuses are specifically designed for marine systems. Their IP66 waterproof rating and robustness make them perfectly suited to the demanding conditions encountered aboard ships and boats.

The weight of a pack of these fuses (containing 2 pieces) is approximately 0.02 kg.

The main function of a fuse is to protect electrical components and wiring in a circuit from damage caused by overcurrent or a short circuit. If excessive current flows, the fuse filament melts, breaking the circuit and preventing potential damage or even fires.

The terms AMI and MIDI are often used interchangeably to refer to a compact bolt-on fuse type of medium power. The term 'AMI' is sometimes a manufacturer-specific designation (such as Amp Trap MIDI), while 'MIDI' is a more generic term for this fuse format. In the case of this Blue Sea product, 'AMI/MIDI' indicates that it matches this standard format, providing intermediate protection between small blade fuses (ATO/ATC) and high-power fuses (ANL).

This 50A fuse is recommended for protecting medium-capacity circuits in marine systems. It is ideal for applications such as:

Main switchboardsBattery chargersMedium-capacity power invertersNavigation and marine electronics systems requiring 50A protection

No, AMI/MIDI fuses, like most fuses, are single-use devices. Once a fuse has blown due to an overcurrent, it must be replaced with a new fuse of the same amp rating to restore circuit protection.

These fuses are compatible with systems operating at 12V and 24V, covering most marine electrical installations.

These AMI/MIDI fuses are compatible with fuse holders specifically designed for AMI or MIDI fuse types. It is essential to use a fuse holder suited to this format to ensure a secure connection and effective protection.

No, this AMI/MIDI fuse cannot directly replace an ATO/ATC fuse (blade fuses) or an ANL fuse (high-power bolt-on fuses) because they have different physical formats and mounting characteristics. Each fuse type requires a specific fuse holder. The AMI/MIDI fuse serves as an intermediate option in terms of power and compactness.

Yes, these fuses are fully compatible with both 12V and 24V electrical systems, making them versatile for various marine installations.

Yes, these 50A fuses can be used in marine solar panel installations, provided the protected circuit's amperage (e.g., between the charge controller and the battery) does not exceed 50A and the system operates at 12V or 24V. Always consult your solar installation specifications to select the appropriate fuse amperage.

A blown fuse typically has a broken or melted internal filament visible through the transparent body. Some fuses may also feature a visual indicator. If the protected circuit is no longer functioning, the first troubleshooting step is to visually inspect the fuse or test it with a multimeter in continuity mode.

No, AMI/MIDI fuses do not have a specific orientation. They can be installed in any direction in the compatible fuse holder, as long as the connections are properly tightened and secured.

When replacing a fuse, it is crucial to take the following safety precautions:

Always disconnect the circuit's power supply before handling the fuse.Use insulated tools where possible.Make sure the new fuse has the same ampere rating as the one it replaces.Check that the fuse holder is clean and in good condition.Do not touch live terminals.

For installation or replacement of an AMI/MIDI fuse, you will generally need an appropriate wrench or socket to tighten or loosen the mounting bolts on the fuse holder. Make sure to use the correct size tool to avoid damaging the bolt heads.
