Feeo Electric Tells You What Is The Time/Current Curve?

The time-current characteristic is a curve giving the time, for example the pre-arcing time, as a function of the prospective current under stated conditions of the operation. The time-current curve is used to achieve co-ordination with the other fuses or devices in the same installation. The time/current characteristics or melting curves are represented by graphs showing the operating time of the fuse in relation to current. The presentation of the time/current characteristics are specified in the IEC Standards.
