Circuit Breakers FI44.30, 63A, 300mA, 4p Earth Leakage CB
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 10 mA and 30 mA fault current ratings, especially when high distributed capacitance or other leakages cause excessive nuisance trips at lower fault currents. Applications for the 300 mA rating are equipment protection and fire prevention by limiting the energy of a fault to less than the minimum ignition energy for many materials.
