Multymeter.com – In an electrical and electronic installation, this tool is very important, but maybe we don’t know how this tool works, it can be installed on an electrical installation network, and also on an electronic equipment that we always use on a daily basis. this is as a safety for humans and also as a safety for other devices that are connected in the same network on an electronics, so as to avoid even greater damage. This tool is commonly called “FUSE”.
Usually we find fuses in various shapes and sizes, even with different names, but their function is none other than electric circuit breakers. Fuses do not have positive and negative poles, so the wiring can be placed anywhere between the two pins of the fuse.
The following are some types of fuses commonly installed in electrical and electronic installations:
This fuse is an old model type, usually used in private residential electrical installations, the way it works this fuse will disconnect itself if there is an excess voltage and if there is a short installation. This type of fuse has started to be abandoned with the automatic type.
2. AUTO FUSE
This fuse works similarly to the first type of fuse, the difference is that this fuse is already an automatic system, so if there is an overvoltage, or a short, the switch or button will disconnect the current automatically, and to reconnect it just by pressing the button (switch). This fuse has also begun to be left behind in every installation of a residential electrical installation network.
3. MCB (Miniature Circuit Breaker)
MCB (Circuit Breaker) is commonly used as a current limiter, but in modern electrical installation networks to date, this tool is also commonly used as a safety device for every electrical installation network in every building and housing, to replace conventional fuses as shown in figure 1 and 2. The way this tool works is to disconnect the electric current caused by excessive use of electricity, and also if there is a short in the electrical installation network. This tool is equipped with a switch as a breaker and a current liaison. MCB (Miniature Circuit Breaker) has several the size of the amperage that can be adjusted according to need, 2 Ampere, 4 Ampere, 6 Ampere, 10 Ampere, 20 Ampere, and others.
This tool is usually found in every iron, its function is to regulate the heat temperature needed by the heater on the heater. The characteristic of this tool is that the indicator light is not lit, and of course the iron heater cannot be hot, because the indicator light and heater are supplied via Thermofuse. For the Thermofuse size, the iron usually uses a value of 250 ° cc 250V 10A.
We often encounter this thermostate in electronic equipment, such as: Rice cookers, and drinking water heaters (Dispenser). Its size can be adjusted to those of any electronic device, for example the size of 70 ° cc 250V, 80 ° cc 250V, and others – other.
6. ELECTRONIC FUSE
For an electronic technician, you must often encounter this small object, this fuse is usually used as a safety coil for copper wires on the fan dynamo. With this fuse, the dynamo cable coil is protected from short.
7. BLADE FUSE
This fuse is also called a plug-in fuse, which is usually found in every motorized vehicle. It has an amperage rating according to the color of the blade fuse body. Yellow: 20 Ampere Orange: 5 Ampere Brown: 7.5 Ampere Red: 10 Ampere Blue: 15 Ampere White: 25 Ampere Green: 30 Ampere.
8. CARTRIDGE FUSE
Tube fuse is another name for this cartridge fuse. This tool is commonly found in electronic devices, such as televisions and others, as a safety for other electronic components in an electronic network. Has a value written on the fuse plate, ranging from 1 Ampere, 2 Ampere, and other.***
