Electronic overcurrent releases
First I want to present an overview of the electronic overcurrent releases (short form: trip units) with more
details.
Because this is the most important device of the IZM circuit breaker.

Short time delayed short circuit range:
standard: Isd = const.
modification: I²tsd = const.
