0452003.MRSN Application Field and Working Principle

The 0452003.MRSN type low voltage fuse link is an ideal protection device which is widely used in motor start, lighting, capacitor, distribution network, electronic equipment, metering and other fields, with characteristics of small size, light weight and reliable performance. The cylindrical 0452003.MRSN fuse link is rated at 250Vac/dc and available in five different current ratings that range from 6 to 80A.

The 0452003.MRSN type low voltage fuse link mainly consists of a metal body, an outward-pressing contact head, and an arc extinguishing operating element. The arc extinguishing operating element is the key component of the 0452003.MRSN type low voltage fuse, which comprises two components: a melting metal wire and a support body. The melting metal wire links the outward-pressing contact head at one end and the support body at the other end, and when the current exceeds the fuse rating, the melting metal wire fuse melts. When the contact head and the support body are mutually separated, the connection between the two is cut off and the circuit is thus broken to protect electrical equipment.

In general, 0452003.MRSN type low voltage fuse link has strict requirements in terms of materials and components, and its excellent performance and security are guaranteed. With a high response speed, the 0452003.MRSN type low voltage fuse link has the advantage of quick current breakage under extreme conditions, greatly reducing the damage of the overvoltage current on the electrical equipment. This makes the 0452003.MRSN type low voltage fuse link more suitable for a wide range of the global market, especially in places and occasions where the wiring environment is intense and the space is limited.

In summary, 0452003.MRSN type low voltage fuse link can be widely used in the fields of motor start, lighting, capacitor, distribution network, electronic equipment, metering and other fields. The working principle of 0452003.MRSN type low voltage fuse link is: once the current exceeds the fuse rating, the metal wire fuse melts, the outward-pressing contact head and the support body are mutually separated, and the connection between them is cut off to achieve the effect of isolating the current.
