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
