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, espe-
cially when high distributed ca-
pacitance or other leakages
cause excessive nuisance trips at
lower fault currents. Applications
for the 300mA rating are equip-
ment protection and fire preven-
tion, limiting the energy of a fault
to less than the minimum ignition
energy for many materials.

15g with impact force half-cycle sinusoidal and 11ms duration, 18 impacts total with 6 on each
principal axis (3 impacts each face). FI is DIN Rail mounted during the test, and electrically loaded
with 25% of Fault RC. Successful testing required no trip during the test, no damage and no loosened
parts.
5g, at frequency of 55Hz to 2,000Hz, applied for 35 ± 5 minutes along each of the three principal
axes, plus 5 minutes of application at every established critical resonant frequency. FI is DIN Rail
mounted during the test, and loaded with 25% Fault RC. To pass, the FI did not trip at 25% Fault RC,
but did trip between each of the principal axis tests when the fault current was raised to 125% Fault
RC, and there was no damage and no loosened parts. Suitable for machinery and mobile vehicle
applications.

Housing Class
Non-Sinusoidal Fault
Ingress Protection (IP) Class 40; internal working components and live parts (excluding terminals) are
protected against ingress of solid objects greater than 1mm diameter (class 4-), but have no
protection from ingress of water (class-0).
The FI is tested and approval stamped for tripping sensitivity to non-sinusoidal fault currents, which
become zero or almost zero within one cycle of the line frequency. Waveforms and allowed trip-
current ranges are as follows:
1.

AC Sinusoidal Fault - 0.5-1.0 times Fault RC
Pulsating DC Fault;
Positive and Negative Half-Waves - 0.35-1.4 times Fault RC
Phased Half-Wave, 90° - 0.25-1.4 times Fault RC
Phased Half-Wave, 135° - 0.11-1.4 times Fault RC
