3)
Minimum short circuit current for selected fuse or custom value
Limit Uc
Conventional touch voltage limit
[12 V, 25 V, 50 V]
1)
Applicable if Fuse type is set to Off or Custom.
2)
With Plug test cable or Plug commander Z auto test is measured in the same way
regardless of the setting. The parameter is meant for documentation.
3)
Ipsc (LPE) is considered if Protection is set to TN or TNrcd. Ipsc(LN) is always
considered.
