DIN-Rail EMC/RFI Filter with Minimum Leakage Current
3-Phase Filters FN 3025 / FN 3026
Compact state-of-the-art filter concept
Light weight plastic enclosure design
Minimized filter leakage current
Hinged safety covers
Approvals
Revolutionary embedded filter terminals
Chassis or DIN-rail mounting option
Selectable performance level
Design protected by European patent (EP 1727280)
Environmental friendly design without potting
compound
Features and benefits
FN 3025 filters are designed for traditional chassis
mounting
For extra fast installation, FN 3026 filters can
comfortably be snapped-in on TS 35 DIN-rails
Two different performance levels are of- fered (L
types, P types). The suitable filter can be selected by
choosing the required performance level, the
admissible leakage current and the preferred
installation style
A plastic housing and a metal ground plate are
cleverly combined to get the lowest possible
product weight without compromizing EMC
behavior
The embedded jump-terminal system from
Schaffner guarantees user-friendly hand- ling as well
as fast and reliable electrical connection
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 delivery package without
causing extra cost

* Calculated at rated current, 480 VAC and cos phi = 0.8. The exact value depends upon the efficiency of the drive, the motor and the entire application.
** Maximum leakage under normal operating conditions. Note: if two phases are interrupted, worst case leakage could reach up to 10 times higher levels (at 520 VAC/60 Hz).

Installation
FN 3025/FN 3026 are delivered with closed plastic
covers and unfastened terminals. To install the filter
please proceed as follows:
Mount the filter on a metal surface with four screws
or snap it onto a TS 35 DIN- rail.
First connect the green/yellow wire to the earth stud
of the filter.
Gently lift the two hinged plastic covers.
Connect phase wires with cable lugs by pushing
down and tightening the screws.
Please note the torque recommendation on top of
the filter.
Push the covers back into their locked position to
finish the filter installation.
