A fuse is an electrical/electronic device that protects a circuit from various electrical faults such as current and overload. Fuses can be considered as a sacrificial element in a circuit, as they act as a weak link in the entire circuit. they do.
A simple fuse consists of a small conductive material with low resistance and is placed in series in the circuit. The cross-section of this conductive material is designed in such a way that it allows a certain amount of current to be allowed in the circuit. When the existing current If the circuit exceeds this allowable value (which may be caused by an overload, short circuit, or load mismatch), this excess current will melt the conductive element in the fuse and open the circuit. It interrupts the power supply and thus, the rest of the circuit is protected from damage. Fuses are very simple and inexpensive devices and have been used as protective equipment for over a hundred years. There are different types of fuses available in the market for different types of applications such as residential, industrial, automotive, etc. See the price of all types of cable trays here.
Classification of fuses
Even if the work of a fuse seems simple, there are different ways to classify all types of fuses. In one classification, fuses are divided into two categories, single-use fuses and resettable fuses, based on usability.
Disposable fuses, when blown in a circuit, must be replaced manually. These types of fuses are often used in electrical and electronic systems in homes, industries, consumer products, etc. Resettable fuses, on the other hand After the error occurs by changing its resistance, they are automatically reset. Different types of fuses are available for different types of applications. In one main category, fuses are divided into AC fuses and DC fuses based on the type of circuit used. AC fuses are again divided into high voltage (HV) fuses and low voltage (LV) fuses. become
High voltage (HV) AC fuses are used for voltages above 1000 V and low voltage (LV) AC fuses for voltages below 1000 V. Low voltage (LV) fuses are again classified as cartridge fuses (fully enclosed type), acceptable fuses. (semi-enclosed type), switch fuses, drop fuses and striker fuses are classified.

DC fuses
The main difference between DC and AC fuses is the size of the fuse. In a DC circuit, when the current exceeds the limit, the metal wire in the fuse melts and disconnects the rest of the circuit from the power source. Since DC is a constant value and is always above 0V, there is a possibility of an electric arc between the melted wires, which will be difficult to prevent and extinguish. Hence, usually the electrodes of DC fuses are compared to AC fuses are spaced further apart. This minimizes the chance of arcing, and since the distance between the electrodes increases, the size of DC fuses is relatively large. be much smaller.
45 degree cable tray bend or CABLE TRAY BEND 45 is used in places of the cable route where the cable route is changed at an angle of 45 degrees. It is made in two modes of hot plating (in wet areas) and cold (galvanized fabric) and Four bends or six bends are used according..

REDUCER FOR CABLE TRAY is used in places where the volume of cables is reduced (reducer conversion) or the volume of cables is increased (increase conversion). The conversion width starts from 100 mm and up to 1000 mm is variable. The height or conversion wall is made from 20 mm to 250 mm. The length..
