WARNING:
For filter connection (divert to ground or earth the unwanted frequency) considering such devices can
produce small leakage current towards earth or ground (this current amounts to "some" amount of
milliapmeres). For these precautionary reasons, it is necessary to connect the filter to earth prior t
connecting the power supply.
In relations to leakage current, remember that it must be considered when sizing differential switch, thus
avoiding undesired interventions. The precise data relative to our filters can be found below.
Mechanical and Electrical Characteristics
Below is a table showing the electrical characteristics of our recommended filters. Pay particular attention to
Leakage, differential adjustments, and nominal current in accordance with operational temperature.:
Type Current Rating Leakage Current Power Loss Weight
(A) (mA) (W) (Kg)
FN355-3 3 (40°) /3.2 (25°) 0.41(400V 50HZ) 1.5 0.25
FN251-4 4 (40°) /4.6 (25°) 1.31(400V 50HZ) 5.5 0.75
FN251-8 8 (40°) /9.2 (25°) 1.31(400V 50HZ) 7 0.75
