02302.25DRT2W Application Field and Working Principle

In the field of power and grounding, fuses are one of the most widely used protection methods. 02302.25DRT2W is a current-limiting fuse with excellent performance, small size, light weight and low price and is ideal for medium voltage applications.

When an electric current passes through the body of a fuse, the fuse will heat up, and when the temperature of the current exceeds the preset temperature, the fuse will break the circuit and the current will be released. This helps to protect against electrical overloads and ensure the safety of personnel and property.

In the process of actual operation, when the current of the circuit is too large and exceeds the rated current of the fuse, the heat generated by the current will increase the temperature of the fuse, and when the temperature goes beyond the thermal melting point of the fuse, the fuse will melt and break the circuit. At this time, the contacts of the fuse will melt and open the circuit, and the current will not be able to pass through the fuse. Then the circuit will be denied to prevent damage to the electrical equipment and ensure the safety of the personnel.

02302.25DRT2W is an ultraviolet and visible current limiting fuse which is specially developed for the power grids. It has reasonable internal structure and dimension design. The adopted arc tube material has good melting and arc extinguishing performance, good product consistency and excellent protective performance. The product is mainly used in power distribution protection, circuit control, short circuit current protection and other applications.

02302.25DRT2W can effectively reduce the number of times of switching operations in electrical distribution systems, and has excellent arc extinguishing performance and current limiting ability. It has quick cut-off speed with low over-current tripping current and good selectivity. Its internal structure is compact, small size and light weight.

02302.25DRT2W can be used in the power distribution system with a maximum voltage of 35 kV and a frequency of 50 Hz. It is suitable for the low voltage power distribution system and the international standard dimensions are in accordance with the French standard.

In summary, 02302.25DRT2W is an ideal and safe choice for medium voltage applications, with small size, light weight, low price and excellent performance. It can effectively protect the power grid and personnel safety.
