Fuses are electrical devices designed to protect electrical circuitry from damage due to an overload or short-circuit. When a preset level of current passes through the fuse, it will blow or disconnect, thus disconnecting the circuit from the mains supply. The 0897004.N is an ultra-fast acting (UF) fuse that is used in medium voltage applications and is uniquely designed to provide superior current limiter capabilities.In order to understand the application field and working principle of the 0897004.N fuse, it is necessary to first gain a basic understanding of the components and how they work together. The fuse is made up of two components - the primary element and the element holder assembly. The primary element is the core of the fuse and is the part that is responsible for the current-limiting capabilities. This component is usually made from a copper alloy and is responsible for converting the electrical energy into heat energy. This heat energy is then transferred to the element holder assembly which contains a terminal, a fuse-holder and a thermo-sensitive trip device.The terminal is the contact point where the fuse is connected into the circuit. It provides a secure connection between the primary element and the fuse and allows for both electrical current and thermal energy to be conducted safely. The fuse-holder assembly is the part which houses the primary element and includes a spring-loaded trip device. The spring-loaded trip device is responsible for detecting when the fuse has exceeded its rated current limit and will automatically open the circuit once the limit is reached.The working principle of the 0897004.N is based around the basic principles of current limiting. When operating within its rated current, the primary element will convert the electrical energy into heat and will transfer this heat onto the element holder assembly. As more current is applied to the element, the heat will increase which will cause the thermo-sensitive trip device to activate. Once activated, the circuit will be opened, preventing any further electrocution and damage to the circuit.The application field of the 0897004.N fuse is mainly based around medium voltage applications. This type of fuse is ideal for applications which require a higher level of protection from short-circuit and overload hazards. It is regularly used in transformers, electric motors, lighting circuits and other applications with power distribution systems. In addition to this, the 0897004.N can also be used in commercial and industrial applications such as air conditioners, pumps and refrigeration systems.In conclusion, the 0897004.N fuse is an ultra-fast acting fuse designed specifically for use in medium voltage applications. Its primary element and element holder assembly combine to provide superior current-limiting capabilities and are responsible for the basic working principle of the fuse. The fuse is suitable for use in transformers, electric motors, lighting circuits and other applications with power distribution systems, as well as being useful in commercial and industrial applications.
