Fuses are a type of electrical product that has been around for many years. They are used to protect circuits from overloads and short circuits. The 0235.400VXP is a medium voltage fuse. It offers protection against high fault currents in 3-phase circuits by providing an instantaneous over current protection.

0235.400VXP Application Field

The 0235.400VXP is used in medium to high voltage applications up to 14kV AC, 480V DC. It can be applied in a variety of industrial applications such as lighting and power. It is mainly used to protect power distribution transformers, alternators, motor controllers, and other electric distribution equipment.

Working Principle

The 0235.400VXP fuse has a pressure-operated element. When the current through the fuse exceeds the rated fuse current, the element melts and forms an arc. This stops the flow of current and the energy released through the arc fuse melts the element, thereby breaking the circuit and protecting the electrical equipment from over-current.

The 0235.400VXP fuse is constructed of an element, puffer, baffle, end cap, and fuse link. The fuse link is made of high temperature resistant copper and filled with a special filling material to absorb arc energy. The grill and end cap provide venting during operations, while the puffer provides for a safe air gap when micro-operation. The baffle provides mechanical support to the element.

Advantages

The 0235.400VXP offers excellent overload and short circuit protection with its instantaneous operation and high interrupting ratings. It offers lower power losses and smaller size. The pressure-operated design allows for greater current ratings in a smaller package. This also makes them less likely to fail due to vibration than conventional thermal fuses. Additionally, due to the high temperature-resistant copper fuse link and special filling material, this fuse offers good temperature and arc resistance.

Conclusion

The 0235.400VXP fuse is a pressure-operated fuse designed to provide protection for 3-phase circuits with high fault current. It offers excellent overload and short circuit protection with its instantaneous operation and high interrupting ratings. It has a smaller size and lower power losses compared to conventional thermal fuses. Additionally, the pressure-operated design allows for higher current ratings. The high temperature-resistant copper fuse link and special filling material also provides good temperature and arc resistance.
