Short-circuit withstand

Compare cable thermal withstand with the entered fault current and clearing time.

Adiabatic k²S² versus I²t screening. Confirm material/temperature constants, clearing energy and applicability of the adiabatic approximation.

Results

Enter inputs above, then tap Calculate.

Adiabatic screening only - use manufacturer k/t and protection curves for compliance.

Check the stated method and limits against your installation. Results are calculation aids, not certification.
