*'''Dynamic contact separation''' (without considering magnetic fields caused by the current path)
: <math>F_A \approx 0,8 /cdot I_2xl^2</math>(Rule of thumb with F<sub>A</sub> in N and I l in kA)
*'''Contact voltage and max. contact temperature'''
: T_k max</submath> T_kmax \approx 3200 U<sub>KU_K</submath>
*'''Contact resistance at higher contact forces (according to Babikow)''' : <br /math>R<sub>KR_K = cF_k^{-m}</submath> = cF -m KFor F<sub>K</sub> between 10 and 200 N<br/>c = material dependent proportionality factor<br/>
m = shape dependent exponent of the contact force
