Function description
Four step phase
overcurrent protection
6.4.2 Functionality
The four step phase overcurrent function for single pole tripping (OC4SPTOC, 51_67) has an
inverse or definite time delay independent for each step separately.
All IEC and ANSI time delayed characteristics are available.
