Fuses have been a vital part of electrical systems since the late 19th century. They are used to protect both the equipment and the people operating it from short-circuits and overloads. But as applications have become more complex, newer types of fuses have been developed to meet the increased demands. One of these is the CDN250 type of specialty fuse.

The CDN250 fuse is a current limiting fuse designed for use in higher short-circuit current applications. It is a three-phase current limiting fuse that can be used in places where regular fuses are inadequate. With an interrupting rating of 101kV, it is suitable for protecting components, like transformers, from short-circuits and can be used in applications up to 480v.

The most common applications for the CDN250 are in three-phase circuit breakers, switchgear, motor control centers, and transformers. It’s also used in utility substations, power distribution systems, panel boards, and capacitor banks. Additionally, it is well-suited for other special applications where current compensation, constant current limitation, or high current limiting are necessary.

The working principle of the CDN250 is based on its special electro-magnetic property. When a short-circuit occurs, the coil inside the fuse sucks in the flux created by the electrical current. This flux causes a magnetic field that pulls the fuse link away from the fuse holder, increasing the distance between them. This forces the circuit breaker to open and trips the fuse, ending the short-circuit.

What makes the CDN250 unique is that it is capable of providing a constant current limitation due to its built-in compensation element. This means that the severity of the short-circuit is reduced, allowing the associated components to be defended more effectively while still providing reliable circuit protection.

The CDN250 is designed to perform well in tough environments, featuring a stainless steel construction that is highly resistant to both corrosion and shock. It also has a vacuum encapsulated design that prevents premature failures caused by arcing or current spikes. The fuse is also designed for easy installation, with panel mounting brackets and color-coded leads.

The CDN250 is a reliable and cost-effective fuse that offers superior protection in high short-circuit current applications. Its unique design and construction allows it to provide reliable current-limiting, protecting not only the components but also the operators from potential harm. It is a valuable addition to any circuit protection toolbox and is sure to provide years of reliable service.
