Ground-fault
protection
The following data refers to sinusoidal fault currents of 50/60 Hz:
With a motor current between the 0.3- and 2-fold set currentI
e
, the
unit trips at an ground-fault current that is 30 % of the set current.
With a motor current between the 2- and 8-fold set currentI
e
, the unit
trips at an ground-fault current that is 15 % of the motor current.
The on-delay is 0.5 to 1 s.

diagram VII
in the graphic section (I
GF
= ground-fault
current, I
trip_GF
= operating current in the event of a ground fault).
