20A Standard Car Auto Blade Fuse 20 Amp ATO - Pack of 10

Product Information

Blade-type fuses are also known as Plug-in fuses, developed first in the 1970s. It is the most common automotive fuse type used in the car industry. A blade fuse is a type of automobile fuse consisting of two blades/prongs and a fuse-element (A metal wire connecting both blades) encased in a semi-transparent color-coded plastic. The purpose of a transparent plastic housing is for easy identification of a broken fuse. size, type AGB, 0.177in (4.5mm) diameter by 0.588in (14.9mm) long (frequently replaced with 5mm diameter by 15mm long international size fuse (aka 5 x 15mm - now more readily available) [13]

There may be a fuse for ignition off draw (IOD), which controls the drawing of electric current in a vehicle while it is shut off; removing this fuse while the vehicle is shut off for more than a few weeks will prevent excessive depletion of the battery. [ citation needed] Blade type [ edit ] Blade type fuses come in six physical sizes: Micro2, Micro3, low-profile (LP) Mini, Mini, Regular, Maxi LP-mini (APS), also known as low-profile mini. Unofficially, the "low-profile mini" fuse is sometimes incorrectly called "Micro" since the term means smaller than mini, but recently fuses using the Micro name have been released. Once you have replaced any necessary powerpoint fuses, locate your fuse box, using your torch if necessary. Ensure that the master switch is in the off position. It should be following a trip, but you should always make sure that this is the case

Cylindrical fuses are a basic design and many of the most widely used and familiar models fall within this category. HRC Fuse Types There are several automotive fuse types, but today we’re talking about the blade-style fuses found in most modern cars made after 1980. Keep in mind that there are several different types of blade fuses beyond the standard ATC size too, including Mini (ATM), Maxi (APX), and Low-Profile Micro (ATT) styles. In-line fuse holders, with two standards: IEC publication 257 1968 Amendment no. 2 to this publication dated January 1989 and UL-standard no. 512. They help to save space. An inline fuse is often seen in add-on electrical accessories, where the manufacturer does not know the electrical current limit of the circuit you are going to patch into. This offers sufficient protection for that individual accessory, without regard to any other devices that might share the same circuit. That’s why being able to identify them by their color is such a big help. We looked to the fuse experts at Bussman to help compile these handy guides. First let me make it clear that ATO/ATC only relates to the design of the housing body of the fuse, not to anything else. Car manufacturers made plastic housing bodies of a fuse in two different designs.

You can use Ohm's Law to calculate the required rating for a fuse. Divide the power of the attached device (measured in watts) by the voltage of the power supply. If the result is a fraction, round this up or down. When a fuse blows, the electrical supply to a particular circuit is immediately cut off. This lowers the risk of fire and prevents damage to the wiring. The blown fuse can safely be replaced without the risk of electrocution. Are Old Fuse Boxes Illegal? Striker fuses are fuses fitted with a spring-loaded striking device that can trip adjacent switches and also indicate that a fuse has blown. Type C FusesIn the first design, the bottom of the plastic housing body of a fuse is kept open, exposing the fuse-element to the atmosphere, called the ATO fuse. Where the “O” at ATO stands for “Open” housing space between the two blades of the fuse.

Most UK plugs are fitted with a 3 amp or 13 amp fuse. 3 amp fuses are used with a range of lower power domestic goods and tools, including lamps, TVs, and drills. Meanwhile, higher power goods such as washing machines, kettles and toasters normally require a 13 amp fuse. What Happens When a Fuse Blows? As explained above, the first steps to replacing a car fuse are to locate the fuse box and the blown fuse and buy a new fuse of the same type, size, and current rating. Once you have the new fuse, you will need to carefully insert it into position within the fuse box or housing. Make sure to insert it into the correct location where the blown fuse was situated. Electric vehicles (EV) fuse is a high-voltage, high-current rating fuse. It is used in high-voltage batteries or hybrid electric vehicles for protection from overcurrents. Strip Layer Of Inside EV Fuse (Source Jehugarcia YouTube) There are multiple different types of automotive fuses. Varying types and sizes will be needed for dealing with specific electrical equipment within the vehicle. For this reason, it is common for a single car to include many different types of fuses.Class of fuses used to protect the wiring and electrical equipment for vehicles Mini / Regular / Maxi blade-type automotive fuses, side and top views. The top metal surfaces can be tested using multimeter probes. Automobile electrical circuit breaker with resettable switch The definition of a D-type fuse is a miniature circuit breaker that trips when the current exceeds the rated level by between ten and 20 times. Therefore, a 16 amp Type D breaker will trip if the current reaches between 160 and 320 amps. Type F Fuses
