Selection and Differences between Quick Break Fuses and Slow Break Fuses.plastic fuse board

　　　　The quick break fuse tube is generally used in the circuit of resistive load, such as electric kettle, electric stove, and Space heater with electric heating wire. Because the electric heating wire is a resistive load, and the working current of resistive load is basically unchanged, the quick break (quick fuse) fuse is required. Alternatively, quick break fuses may also be used in circuits that require the protection of sensitive and valuable devices such as ICs. When the load experiences a short circuit, it is necessary to fuse it in a timely manner for protection.　　Slow break fuses, also known as delay fuses, are mainly used for inductive or capacitive loads, such as square fuses, circular fuses, plastic encapsulated miniature fuses, which are generally very common in switching power supplies. In the switching power supply, there is a Electrolytic capacitor with a very large capacity. When the capacitor is first powered on, it is close to short circuit, and its charging current

Disposable blown fuse 2410TS series.resettable fuse 15a

　　　　Disposable fuses belong to patch type fuses. Disposable fuses can be divided into two types based on their fusing speed: fast fusing fuses and slow fusing fuses. The commonly used series of disposable fuses in Shenzhen include 0402FS/TS, 0456FS/TS, 0603FS/TS, 1206FS/TS, and 2410FS/TS. Today we will have a detailed understanding of the detailed specifications and parameters of the 2410TS series of slow melting fuses.　　The current range of the 2410TS series disposable fuse is 0.1A~30A, corresponding to models 2410-0100TS, 2410-0250TS, 2410-0500TS, 2410-0750TS, 2410-1100TS, 2410-1150TS, 2410-2200TS, 2410-2250TS, 2410-1300TS, 2410-1315TS, 2410-1350TS, 2410-1400TS, 2410-1500TS, 2410-1600TS, 2410-1630TS, 2410-1700TS, 2410-1800TS, 2410-2100TS, 2410-2120TS, 2410-2150TS, 2410-2200TS, 2410-2250TS 2410-2300TS. The maximum voltage for commonly used specification parameters is 0.01A~10A, with a maximum voltage of 250V and a segmented capacity of 50A@250V ; The maximum voltage of 12A~15A is 125V

Principle of action of resettable fuse

　　　　The working principle of a resettable fuse is the dynamic balance of energy. The current flowing through the resettable fuse generates a certain degree of heat due to the thermal effect of the current (there is a resistance value in the resettable fuse). All or part of the heat generated is dissipated into the environment, but the remaining heat will increase the temperature of the resettable fuse element.　　During normal operation, the temperature is low and the heat generated and dissipated reaches equilibrium. When the resettable fuse is in a low resistance state, it does not work. When the current flowing through it increases or the ambient temperature rises, if the generated and dissipated heat reaches equilibrium, the fuse will remain inactive.　　If the current or temperature continues to rise at this time, the heat generated will be greater than the heat dissipation, causing a sharp increase in the temperature of the resettable fuse. Therefore, small temperature changes will l

plastic fuse box under stairs.Discussion on the Application of Fuses on LED Beads

　　　　1、 Firstly, analyze the causes of LED bead damage, which are usually caused by the following reasons　　① A sudden increase in power supply voltage.　　② The temperature inside the lamp is too high　　③ Short circuit in the circuit.　　④ Failure to do a good job in preventing static electricity during assembly has caused damage to the interior of the LED lamp beads due to static electricity. Although normal voltage and current values are applied, it is extremely easy to cause damage to LED beads　　⑤ The voltage and current of the circuit are unstable.　　2、 How to protect the circuit of LED beads?　　Answer: Nowadays, many circuits use fuses for overload protection, but disposable fuses are not suitable for LED lamp products because the circuits of LED beads are very different from those of other products. LED bead circuit overload is caused by the overload protection component, which immediately disconnects the LED bead circuit and automatically restores power supply after the circuit is norma
