Kaitselõikur AMI / MIDI - 200 A

The Blue Sea Systems 200 A AMI / MIDI fuse (part number 5260) is an electrical protection device designed for high-current circuits. It is specifically built for marine environments and provides rapid current interruption in case of overload or short circuit, thereby protecting equipment and wiring.

The main function of this fuse is to protect electrical systems from dangerous overcurrents and short circuits. By melting when an excessive current passes through it, it interrupts the circuit and prevents potential damage to connected devices or fire hazards.

This 200 A fuse is recommended for protecting main circuits or power supply branches for high-energy-consumption equipment on board vessels. This typically includes power converters, bow thrusters, winches, windlasses, and other systems requiring robust protection for high currents.

AMI/MIDI fuses, such as model 5260, are designed to handle higher currents and provide superior mechanical robustness as well as better heat dissipation. They are preferred for high-intensity applications. ATC/ATO fuses, on the other hand, are typically used for low to medium-intensity circuits.

This AMI/MIDI Blue Sea Systems 200 A fuse is rated for a maximum voltage of 32 Volts DC.

This fuse has an interrupting rating (AIC) of 2000 amperes at 32 volts DC. This means it can safely interrupt a short-circuit current up to 2000 amperes without disintegrating or posing a hazard.

Yes, this fuse is designed by Blue Sea Systems for marine environments. It is manufactured with corrosion-resistant materials, such as tinned copper for the terminals, and its overall design is suited to withstand vibrations and harsh conditions encountered at sea.

This fuse is compatible with fuse holders specifically designed for AMI or MIDI type fuses. Blue Sea Systems offers a range of fuse holders compatible with this format.

Yes, this fuse can be used in a 24V system. Its maximum rated voltage is 32V DC, making it perfectly suitable for 24V DC applications.

Yes, this fuse is compatible with 12V systems. Its maximum rated voltage of 32V DC exceeds 12V DC, ensuring effective protection for these systems.

Yes, although primarily designed for marine use, this fuse can be used in automotive or other applications requiring high-current circuit protection. It is essential to ensure the fuse’s voltage and current specifications match the application’s requirements and that a compatible fuse holder is used.

To install the fuse, insert it into a compatible AMI or MIDI fuse holder. Secure it using the bolts and nuts supplied with the fuse holder to ensure a solid and secure electrical contact. It is crucial to ensure the circuit is completely powered off before any manipulation.

To install or replace this fuse, you will typically need a socket wrench or an adjustable wrench of the appropriate size for the fuse holder mounting bolts. Make sure you also have protective gloves and safety goggles.

No, AMI/MIDI-type fuses have no specific orientation. They can be installed in any direction in the fuse holder, provided the connections are correctly established and secured.

A blown fuse typically shows a visibly broken internal filament or blackening through its transparent window. If an item of equipment is no longer working and you have confirmed the circuit is live, the fuse is often the first component to check for signs of failure.

Yes, it is absolutely imperative to cut the power supply to the relevant circuit before handling or replacing a fuse. This prevents any risk of electric shock, short circuit, or damage to components.

No, it is critical to always replace a fuse with a fuse of the same ampere rating (200 A). Using a fuse with a lower rating may cause nuisance tripping, while a fuse with a higher rating will not adequately protect the circuit and could cause serious damage to equipment or wiring, or even a fire.

No, the Blue Sea Systems 200 A AMI/MIDI fuse is a single-use protective device. Once it has blown to protect the circuit from overload or short circuit, it must be replaced with a new fuse of the same specification. It is not resettable.
