021702.5MXE

As a protective device, fuses are used to protect electrical circuits and components from over current and overload. They are essential components for any commercial or home electrical circuit. 021702.5MXE is a type of fuse manufactured by Astec Components that offers both overcurrent and overload protection. It is a medium voltage ceramic fuse designed for industrial applications, with a maximum voltage of 17.5kV and a maximum current rating of 202A.

The 021702.5MXE fuse is a high frequency, low noise, ceramic fuse with superior short-circuit protection characteristics. It has a cylindrical shape and comes in two different sizes: 5mm and 6mm. The fuse is composed of two parts: a top or elbow, made of tin-plated copper, and a bottom or contact, made of zinc or an alloy. The top of the fuse has an internal structure that separates the conductors and protects them from the heat generated by the working current. The contact is a two-part, tin-plated copper contact, designed to provide reliable operation and low maintenance.

The working principle of the 021702.5MXE is relatively simple. When an overload occurs, the current flows through the fuse until the two contacts that form the fuse become hot enough to melt the inner structure of the fuse, thus breaking the circuit and stopping the current. This process occurs quickly and safely, with minimal damage to the electrical circuit.

021702.5MXE fuses are widely used in heavy-duty, industrial applications such as transformers, generators and other high-voltage devices. They are also suitable for use in motors, switches, solenoids and other equipment. The fuse offers superior protection against short circuits, and can be used in extreme temperature conditions, with a maximum ambient temperature of +85°C. The robust construction of the fuse makes it highly resistant to mechanical and thermal shocks.

In conclusion, 021702.5MXE is a high-performance medium voltage ceramic fuse with superior short-circuit protection capabilities. It is suitable for use in a wide variety of industrial, commercial and home applications, and offers reliable, safe and economical protection against overloads and short circuits. It is a low maintenance and cost-effective device, which makes it an attractive choice for many applications.
