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 groundfault 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.

Fluctuating Climate Conditions Electrical Shock Protection Impact/Shock Protection Vibration/Seismic Resistance
Environmental Information marked with "Snowflake" approval for -25C to 40C (-13F to 104F) ambient temperature. (Temperature effect on RC: for every 10C temperature rise above 40C decrease RC by 7%.) To maximum 45C, 95% relative humidity. Uninsulated electrically live parts within 30mm of the operating handle are "finger safe" (terminal screw heads) and uninsulated live parts within 100mm of the operating handle are "back-of-hand safe" (terminals). 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 tripcurrent ranges are as follows: 1. 2a. 2b. 3. 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 Pulsating DC on 6mA DC (continuous) Base - Max. 1.4 times Fault RC + 6mA
