Everything about ANL and Mini-ANL fuse holders
Electrical safety plays a paramount role in the vehicle. For power-hungry systems, the protection of live wires is indispensable. The bestsellers in this category are: Masori 20 mm²-50 mm² ANL circuit breakers splash-proof, SMD FB-2 Heavy Duty Double ANL circuit breakers aluminum, Audio System Z-FDBG 2-4 / Z-DB 9. If you want to jump directly to the most popular brands, we recommend taking a look at: Masori, SMD, Audio System.
What is the purpose of a fuse holder?
A fuse holder is used to protect the power cables in the car and those of the sound system against overload and short circuits. The fuse rating depends on the cross-section of the cable. Below, we provide an example of the most commonly used cable cross-sections.
- Cable cross-section: 0.5 mm² - Max. current rating of the fuse: 10 A - Line resistance: 34.20 mOhm/m
- Cable cross-section: 1.0 mm² - Max. current rating of the fuse: 15 A - Line resistance: 17.10 mOhm/m
ANL fuses are equipped with a thin strip of fuse metal that melts at a certain current strength and interrupts the circuit. The housing of the fuses serves as protection against fire and splashing water. Mini-ANL fuses are designed for a maximum current strength of up to 175 A, while larger models protect up to 300 A. Both types of fuses are designed for power-hungry amplifiers. With conductor cross-sections of 35 mm², it makes no difference which type of fuse is used.
What types of fuse holders does Masori offer?
Our range includes small mini ANL fuses for connecting a line and large ANL fuse blocks that provide space for up to 8 power lines. In addition, we offer a model with an integrated voltmeter, making voltage drops immediately visible. The fuses are completely weatherproof and designed for long-term use.

Conclusion
Fuses are essential for safe operation and protect both the hardware and the people inside the vehicle. The fuse holders are available in different designs and sizes and reliably protect the circuits against overload.
Fuses protect the circuits they secure from excessively high current levels that can arise from overload, short circuits, excessive current draw from consumers, or other faults. Defective fuses must always be replaced with fuses of the same rated current. In emergencies, fuses with a lower rated current can be used until the next workshop. Fuses must never be bridged with conductive materials, as this can lead to severe damage to the onboard network, including cable fires. Fuses and their connectors should be protected from dirt and corrosion. Loose or corroded contact plugs must be re-bent or replaced. To protect circuits and wiring against short circuits and overloads due to excessive current flows, fuses are used in automotive technology. There are now a variety of fuse types available on the market, with some designs no longer in use.
Generally, fuse links are used, where a metal strip integrated into the fuse melts and interrupts the circuit when an overload or short circuit occurs. Rather rarely and only for specific applications, such as electric window lifters or central locking, circuit breakers are used, which interrupt the current in this circuit for a certain period of time in case of overload or continuous operation with a bimetallic element.
Glass fuses were primarily common among American and Asian automotive manufacturers until the advent of ATO fuses. Today, these glass fuses are still occasionally used as device fuses, for example in car radios, although they have largely been replaced by ATO fuses. The exact fuse type that must be adhered to during replacement is indicated on the metal caps. For the European market, glass fuses of the size 5 x 20 mm are common, while in the American and Asian markets, fuses of the size 6.3 x 32 mm were often used. Generally, glass fuses are rated for a maximum current limit of 20 A.
ANL fuses are primarily installed in relatively new vehicles and are designed for high rated currents, usually more than 40 A. These fuses are typically housed directly at the vehicle battery in a fuse box and are bolted in place. This type of fuse is standardized according to DIN 43560 or DIN 72581. To avoid short circuits caused by loosening tools, the battery must be disconnected before a necessary replacement of these fuses. If an ANL fuse blows, it indicates a larger problem in the onboard electrical system. It is recommended to have the onboard network checked by a professional workshop to prevent further damage.
ATO fuses were developed around 1976 and were first used in mass production in the 1979 Opel Kadett D. Today, this type of fuse has become standard among nearly all vehicle manufacturers. ATO stands for "Automotive Technology Organization." This type of fuse is standardized according to ISO 8820-3. The advantages of this fuse type include its small space requirement and relatively wide contact blades, which ensure a secure connection in the plug and thus keep contact resistances and voltage drops in the onboard network low. The color of the fuse body indicates the rated current.
