Electrical, Specialty Fuses

Fuses are mechanical or electronic devices used to protect electricity circuits from damage caused by overcurrent and short circuit. One of the important specialty fuses is LA130URD71TTI0280. This fuse is a DC short circ const device with block body type. It can be used in high voltage circuit in a distribution board.

Application Field of LA130URD71TTI0280

LA130URD71TTI0280 can be used in various locations including high voltage switching substations, data centers and streets and highways. It offers protection for electric circuits from current overload, short circuit and insulation failures. It is also used in ground fault and surge protection applications.

The applied voltage rating for this fuse is 5kVAC. The current rating of this fuse is 80A. The design voltage is 6kV. It has a nominal response current of 400A. The rated current, load capacity, volt-amperes and power dissipation is 125VA, 15A, and 1.25W, respectively. The response time of this fuse is 0.2 s.

The fuse links of this type are non-inductive. The housing material used in its construction is UL94V-0 PPO. Its base is made up of high impact nylon UL94-V0. It also has protection against surges up to 6kV.

Working Principle of LA130URD71TTI0280

The working principle of LA130URD71TTI0280 is quite simple. It consists of a fibrous material with a conductor in the centre. This conductor is designed in such a way that it has a high melting point. When the fuse is subjected to an overcurrent, the conductor starts to heat up and the material surrounding it also starts to melt. This melts the conductor, thus disconnecting the circuit.

The advanced working principle of this product lies in the fact that it also offers protection against surges. It contains a special component called a varistor. In case of a surge, this component diverts the energy away from the circuit. It protects the circuit from the surge damage.

LA130URD71TTI0280 is also equipped with a current limiting facility. This enables it to offer protection against any instantaneous current surge that may arise due to a fault in the equipment that is connected to the fuse. It limits the amount of current passing through the circuit and thus, prevents the circuit from getting damaged due to an overcurrent.

Conclusion

LA130URD71TTI0280 is designed to provide superior protection for electric circuits from current overload, short-circuits and insulation failures. It contains various components like the conductor, varistor and current limiting capacitors that help it work efficiently and protect electric circuits. It can be used in various locations such as high voltage switching substations, data centers and streets and highways.
