0438.250WR

Fuses

0438.250WR is one type of fuses widely used in many fields. It is manufactured in a wide range of different amperage ratings and sizes for a great variety of different applications. Its base consists of ceramic tube filled with tin-lead alloy. The tin-lead alloy melts and interrupts the circuit when too much current passes through the fuse. This fuse can be used as primary and secondary protection equipment in electrical circuits or electric appliances.

Application field

0438.250WR fuses are widely used in application field like power distribution system, overhead distribution lines, residential and industrial electrical outlets, circuit breakers, equipment items, junction boxes, building construction, heavy machineries and electronic instruments. It can provide maximum safety to users by protecting them from over currents, voltage fluctuations, leakage of current from the sources. It can be used in both normal conditions and emergency conditions. It has low response time and excellent safety features like excellent durability, overload cut-off protection and fast response time.

Working principle

When too much current passes through the fuse, the tin-lead alloy in the fuse melts and interrupts the circuit. This process is known as fusing. 0438.250WR fuse is a fast acting type and it can respond quickly to excessive current and cut off the circuit within a few milliseconds. When the fuse is blown, the current will stop flowing and the protective action of the fuse is done. The fuse is designed to blow and restore itself each time the current flow surpasses the amperage rating of it.

Conclusion

0438.250WR is an important type of fuse used in many different applications. It can provide good protection from high current and voltage fluctuations. It is a fast acting type of fuse with excellent performance and durability. This fuse is reliable and can be used as both primary and secondary protection equipment in electrical systems or electric appliances. It has low reaction time and excellent safety features like overload cut-off protection and fast response time.
