Blocking logic
The binary input BLOCK can be used to block the function. The activation of the BLOCK
input deactivates the RELEASE output and resets Timer.

Application

The three-phase directional power protection 32P improves the possibility to obtain a
selective function of the overcurrent protection in meshed networks. 32P is used to block
or release other overcurrent protection functions.
