FI EARTH LEAKAGE
CIRCUIT BREAKERS
FI compact Earth Leakage Circuit
Breakers detect and interrupt earth
(ground) faults. They are VDE
approved for the European system
of protecting people, animals,
equipment and property from
dangerous line-to-ground and shock
hazard currents.
US applications include ground-fault
protection of equipment (GFPE)
using the 10mA and 30mA fault
current ratings, especially when high
distributed capacitance or other
leakages cause excessive nuisance
trips at lower fault currents.
Applications for the 300mA rating are
equipment protection and fire
prevention, limiting the energy of a
fault to less than the minimum
ignition energy for many materials.

Fault Trip Current Calibration
FI trips are calibrated at less than fault trip current for ensured safety (Typical trip range between
66.6-83.3% fault trip current, e.g., typical trip at 20-25mA for fault RC of 30mA)
Typical Life
Fully functional after 4,000 operations to DIN/VDE 0664 (CEE27) and 16000 additional fault current trips.

a
For 2-Phase applications, terminal 5 and 6 (next
to Neutral terminals) must be connected to one
phase for the test circuit to be operable.
Note: If the power system has a marked conductor, it must connect through the FI and not be grounded at any
point downstream.
b
Provided with mounted Auxiliary Switch, one N.O.,
one N.C. isolated feedthrough contact (Form X
double make and Y double break), which adds
9mm (.35 in.) to the width dimension.
