3-phase lters
FN 3025 / FN 3026
Advanced EMC/RFI lter concept
with minimum leakage current
Approvals
■
Compact state-of-the-art filter concept
■
Light weight plastic enclosure design
■
Minimized filter leakage current
■
Hinged safety covers
■
Revolutionary embedded filter terminals
■
Chassis or DIN-rail mounting option
■
Selectable performance level
■
Environmental friendly design without
potting compound
Typical applications
■
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 compro-
mizing 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 contrib-
ute 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.
■
Very low leakage current values make
these filter ranges ideally suitable for use
in Japanese electricity networks as well as
in applications which set value on safety
and reliability.
■
Applications with the requirement for
extremely compact filter solutions
■
Applications with tough leakage current
requirements or sensitive earth leakage
detectors
■
Applications with insufficient internal
filtering or moderate interference levels
■
Automation equipment
■
Motor drives and servo drives with short
motor cables
■
Applications including stepping motors
■
Semiconductor manufacturing equipment
■
Electrical cabinets
■
Three-phase power supplies
■
Medical equipment (not patient-coupled)
