MV055F2DAX450E Application Field and Working Principle

MV055F2DAX450E high voltage fuses are mostly used for MV and HV applications for power distribution systems. They are reliable protection devices, suitable for fast fault clearing and superior performance in extreme conditions with minimal downtime. This type of fuse has been approved by many international standard authorities like UL, CE, and RoHS. It is also known for its excellent ratings, strong technical and safety features, and long life.

Application Field

These fuses are used mainly in medium and high voltage electrical systems – including, secondary stations, transmission lines, distribution lines, and other power distribution applications. In addition, they also find application in power supply systems of elevators, electric hoists, stoves, clothes dryers, crane hoists, and air conditioning systems. These fuses are also used as over-current protection for all sorts of circuit breakers, wires, cables, and regulators.

Working Principle

MV055F2DAX450E fuses are designed to provide overcurrent protection for high voltage applications. Their construction consists of three main components – a fuse element, electrodes, and a chamber. The fuse element is a wire inside the fuse, connected to the electrodes. When an overcurrent occurs, it will heat up the fuse element until it melts – breaking the circuit and thus preventing the overcurrent from damaging the equipment. The high-voltage fast-acting fuses also feature an improved temperature coefficient. This ensures fast and accurate response to overcurrent conditions, while providing superior performance.

Benefits

MV055F2DAX450E fuses are reliable, safe, and provide superior protection. They are designed for fast-acting protection, and their design even allows them to be used as back-up fuses. They provide outstanding performance in extreme temperature conditions, as well as long life and high accuracy. The fuses are also UL/CE/RoHs-approved, making them suitable for many commercial and industrial applications.
