company news about Introduction to time delay fuse

        Slow-acting fuse is also called time delay fuse. Its delay characteristic is that the circuit is in good condition when non-fault pulse current occurs and can provide protection against long-term overload.

        The current of some circuits at the moment of switching is more than several times of the normal working current. Although the current peak is very high, it appears for a short time. We call it pulse current or surge current.

        Ordinary fuses cannot withstand this current. If ordinary fuses are used in such circuits, they may not be able to start normally. If larger fuses are used, they will not be protected when the circuit is overloaded. The melt of the time delay fuse is specially processed. It has the function of absorbing energy. Adjusting the amount of energy absorption can make it not only resist the impact current but also provide protection against overload. The standard has provisions on delay characteristics. If the specified characteristics of the standard cannot meet your requirements, you can contact the manufacturer to solve the problem.
