I have a terrible confusion between the following currents:
-Ith as mentionned in IEC 60909-0:thermal equivalent short-circuit current ,the rms value of a current having the same thermal effect and the same duration as the actual short-circuit current, which may contain a DC component and may...
In the event of a short circuit, the circuit breaker shall be capable of breaking all short circuit currents such that:
- the periodic component is less than or equal to the rated value
- the percentage of the aperiodic component is less than or equal to the rated value
My question is: why is...
