General questions / Low and moderate overcurrents

What are conventional non fusing and fusing currents?

What are time/current characteristics?
The time/current characteristics or melting curves are represented by graphs showing the operating time of the fuselink in relation to current. The presentation of these time/current characteristics are specified in the IEC Standards.

The time/current characteristics are used to achieve co-ordination at low and moderate overcurrents with other devices in the same installation. What is a fault current?

What is an overload current?

What is an overcurrent?
