According to the application scope, tubular fuses can be divided into industrial appliances and household appliances; According to the application industry, tubular fuses can be divided into instrument, communication, power supply, lighting, automotive, etc. It is worth mentioning that there are two types of automotive fuses, namely high current and low current fuses. But the more common type of fuse in general cars is medium to low current fuse, and the wiper fuse mentioned today belongs to plug-in fuse. You can see the 25A (colorless and transparent) sign, in fact, this is the safety value of the fuse, so you must sit down before replacing it, but do not change other models. Firstly, the color of the car fuse represents its specifications. The most commonly used fuses are 10A, 15A, 20A, 30A, and 40A. The colors are red, blue, yellow, green, and orange. Secondly, the specifications of automotive fuses are divided into three categories: large, medium, and small. Cars generally
Thermal cutoff, also known as thermal fuse, is a new type of electrical overheating protection element. This component is usually installed in easily heated electrical appliances. In case of electrical failure and heating, when the temperature exceeds the abnormal temperature, the Thermal cutoff will automatically cut off the power supply to prevent electrical fire. In recent years, most of China's household electrical appliances with the main function of heating, such as Rice cooker, electric buckets, electric furnaces, etc., have been installed with Thermal cutoff. However, in case of internal failure of parts, Thermal cutoff can cut off the power supply in time to prevent further damage to the appliances and end the fire caused by this. Like the familiar fuse, the Thermal cutoff is usually only used as the power channel on the circuit. If it does not exceed the rated value, it will not open circuit and will not have any impact on the circuit. The circuit will only open when an e
1、 Current Rating (In) The rated current of a fuse refers to its nominal rated current, usually the maximum current that a circuit can operate. The ability of a fuse to carry current, with each fuse having its specific rated current, which needs to be determined through a clear test condition. Once the current exceeds its rated value (a predetermined period of rated current), the fuse will timely open the circuit. Incorrect selection: Using the current value that the fuse is expected to blow as the rated current value. 2、 Voltage Rating (Un) The rated voltage of a fuse refers to its nominal rated voltage, usually the maximum voltage that the fuse can withstand after disconnection. In order to ensure that the fuse can safely disconnect the short-circuit current in its related circuit, it must be operated at a working voltage lower than or equal to its rated voltage. Incorrect selection: The rated voltage of the fuse must match the circuit voltage! 3、 Ambient temperature The a
The function of car fuses is to maintain circuits (routes) and electrical and mechanical equipment. A car fuse is a type of current fuse. When the circuit current exceeds twice the rated voltage of the fuse, it will melt within a few seconds and have the effect of circuit maintenance. Commonly used for overcurrent protection in automotive circuits. What happens when a car fuse is damaged? The situation is as follows: 1. The car cannot start a fire, and the ignition coil has no power. It is necessary to check if the fuse of the ignition coil is damaged, causing the ignition coil to have no working voltage; 2. The car mounted cigarette lighter cannot be used, and it is necessary to check whether the commercial fuse of the car mounted cigarette lighter in the fuse box is damaged; When the vehicle is driving, the speedometer is zero and the ABS warning light flashes, but the speedometer is normal and the fuse that matches the ABS is burned out.
Choose Fuse Type Choose Standard [UL, IEC...] Choose Voltage Rating [AC or DC] Calculate Rated Current Choose Interrupting Rating [Breaking Capacity] Current Derating Advisor In rush Characteristic ² T] Consultant Pulse Factor [Fp] 1、 Choose Fuse Type The first step in selecting a fuse is to determine the type and size required. Common structures and sizes include the following: 1. Tubular type: glass or ceramic tube body, with a general size of 3.6x10mm 5x15mm 5x20 6.3x32mm; 2. Plastic shell type: PA66 shell, small in size, woven with machine insertion, generally 8.5x8mm 8.5x7.6mm in size; 3. Epoxy resin type: ceramic tube body, surface sealing resin, micro type, woven machine insert, size: 3x7mm; 4. Surface mount: suitable for high-density circuit boards, with dimensions of 0402 0603 1206 6125 1032; 5. Automotive fuses: generally used in conjunction with terminals or boxes, specifically for use in automotive or low-voltage, high current systems; 2、 Choose Standard
The full name of 3C certification is "Compulsory Product Certification System", which is a product qualification evaluation system implemented by the Chinese government in accordance with laws and regulations to protect consumer personal and national safety, strengthen product quality management, and implement it. The so-called 3C certification is the China Compulsory Certificate system. It should be noted that the 3C mark is not a quality mark, but rather a fundamental safety certification. The "CCC" certification mark is divided into four categories The current "CCC" certification mark is divided into four categories, namely: 1. CCC+S safety certification mark; 2. CCC+EMC electromagnetic compatibility certification mark; 3. CCC+S&E safety and electromagnetic compatibility certification mark; 4. CCC+F fire certification mark; China has implemented the National Compulsory Certification System (CCC) since May 1, 2002. Compulsory certification is implemented for produc
