1-phase filters
FN 2450
Safe and ergonomic EMC/EMI filter with
very low leakage current
Approvalsn Light weight plastic enclosure design
n Very low filter leakage current
n Hinged safety covers
n Embedded filter terminals
n Different performance levels
n Environmental friendly design without
potting compound
Typical applications
n A plastic housing and a metal ground plate
are cleverly combined to get the lowest
possible product weight without compro-
mising EMC behavior.
n The embedded terminals from Schaffner
guarantee user-friendly handling and reli-
able, long-lasting electrical connection.
n Captive hinged protective covers contri-
bute to overall safety by offering protection
against unintended contact with life con-
ductors. They are included in the standard
scope of delivery without any extra cost.
n Very low leakage current values make
the filters suitable for grids with very
tough requirements or sensitive GFCIs,
and for applications which set value on
safety and reliability.
n FN 2450 feature an ecologically conscious
construction without the use of potting
compound or banned substances (RoHS).
Used raw materials can be easily separated
at the end of the product life time for pro-
per and environmentally safe disposal.

* The letter following FN 2450_ represents the value of the Y-capacitor and is directly related to the performance and leakage current of the filter. Other Y-capacitor values are available upon request.
** Maximum leakage current under normal operating conditions. Note: if the neutral line is interrupted, worst case leakage could reach twice this level.

FN 2450 are delivered with closed plastic
covers and fastened terminals. To install the
filter please proceed as follows:
n Mount the filter on a metal surface with
two appropriate bolts.
n First connect the green/yellow wire to the
earth stud of the filter.
n Gently lift the two hinged plastic covers.
n Untighten the terminals with an appro-
priately sized screw driver.
n Connect phase and neutral wires with
cable lugs by pushing down and tightening
the bolts.
n Please note the torque recommendation on
the next page.
n Push the safety covers back into their
locked position to finish the filter installaton.
