*** Rise and fall time are defined at 10%...90% and 90%...10% of the nominal value
All single values, which specify a tolerance are typical values
EL3160-60A EL 3400-25A
** Accuracy is defined as the max. allowed difference between actual value and set value, always related to the nominal value.
Example: nom. value is 60A and accuracy is given with 0.2%. A set value of 20A may thus result in an actual value of 19.88A...20.12A.
