SR-5-100MA-AP Circuit Protection

Fuses are used for protection in electrical circuits. They protect against faults like shorts or overloads and can be tailored to meet particular requirements. One example is the SR-5-100MA-AP fuse. This article will discuss its application field and working principle.The SR-5-100MA-AP is a midget fuse, which means it is suitable for use in limited spaces, like consumer electronic products or equipment. It is also UL (Underwriters Laboratory) listed, indicating it meets safety standards. The SR-5-100MA-AP is approved for branch circuit protection and has a voltage rating of 125 volts AC.As for the SR-5-100MA-AP’s physical characteristics, it has a body length of 17.8 millimeters, a diameter of 6.3 millimeters, and a weight of 0.32 grams. The fuse is made of glass with nickel-plated copper ends. The SR-5-100MA-AP has a 1-amp time-delay rating and a 100mA current rating. It is available in 10A, 15A, or 20A time-delay ratings.The working principle of the SR-5-100MA-AP is based on the fact that when current flows through the fuse, it heats up the fuse element. When the current exceeds the rating of the fuse, the heat generated will cause the element to melt, thus breaking the circuit and preventing further damage. The time delay feature of the fuse allows it to tolerate a momentary surge of current without blowing the fuse. This feature prevents nuisance tripping and ensures that the fuse will be able to cope with other circuit faults, such as an overload or short circuit.The SR-5-100MA-AP is designed for use in a variety of applications, including consumer electronics, computers, test equipment, telecommunications, and medical equipment. It is also suitable for use with small motors, which need protection from current fluctuations and overloads. It is safe to use and easy to maintain, as it does not require special tools for installation.In conclusion, the SR-5-100MA-AP is a midget fuse with a 1-amp time-delay rating and a 100mA current rating. It is UL listed and approved for branch circuit protection. The fuse uses the principle of heating the element to interrupt the circuit if the current exceeds its rating. It is suitable for use in many applications, such as consumer electronics, computers, test equipment, telecommunications, and medical equipment, and is also safe and easy to maintain.
