Electrical, Specialty Fuses allow companies to protect suitable electrical circuits and equipment from being overloaded or short-circuited by sudden current surges or by fault conditions. One type of fuse is the Excess Current Limiter (ECL) series, specifically the ECL055-100E fuse.The ECL055-100E is designed to be used with electrical apparatus containing motors. Its use is to protect these circuits from voltage disruptions due to current surges, short circuits, closing of the disconnect switch and other fault conditions. The ECL055-100E has a three pole version for three-phase circuits, and a single pole version for single phase circuits.The working principle of the ECL055-100E is generally the same as that for other fuse types. When the fuse blows, a metal strip in the fuse breaks and cuts off the power. This is indication of a fault or overload in the circuit. The ECL055-100E, however, has some unique features that make it particularly suitable for some applications.The first feature is its ability to withstand high levels of surges and spikes. A surge is a sudden peak in the current in a given electric circuit, while a spike is an even more rapid, instant increase in current. The ECL055-100E has a high interrupting capacity that allows it to interrupt surge and spike currents for up to 26.4 times the rated current, thus greatly reducing the chance of equipment damage should a fault condition be met.The second feature is its ability to limit overcurrent in different ways. It has a built-in, automatic resetting current limit technology that limits overcurrent when the fuse is reset after a fault. It also provides ongoing current limitation even when no faults are present, helping to keep the electrical circuit stable.The last feature of the ECL055-100E fuse is its ability to detect high distances off of ground. This is useful for systems where it is important to use different ground points to reduce voltage and current surges from undetected leaking currents. It can also be used to detect extreme temperatures which help to prevent fusing failures due to heat or cold.The ECL055-100E fuse is suitable for a variety of applications, including motor control centers, computer circuit boards, automotive alternator circuits, and heater circuits. It is UL listed, meaning it meets the relevant safety requirements, and it is also RoHS compliant. It is also corrosion resistant and has a long service life.In conclusion, the ECL055-100E fuse is an excellent choice for protecting motor circuits from current surges and spikes. It offers a variety of features that make it suitable for more demanding applications, and provides ongoing current limitation even when no faults are present. Its ability to detect high distances off of ground and extreme temperatures make it a reliable and safe choice for many applications.
