DATASHEET 3-Phase Filters FN 3100
EMC/EMI Filter for Regenerative Motor Drives
Exceptional broadband attenuation performance Approvals
from 10 kHz up to 30 MHz
Equally suitable for conventional and
regenerative motor drives (latter with additional
line reactor only)
Slim and user-friendly book-style design with (FN 3100 up to 150 A)
touch-safe terminal blocks for minimum space
and maximum safety
Enables compliance with Class B limits
Features and benefits
High performance filter for mainly industrial motor
drive applications with significant interference levels
Attenuation performance for Class B compliance in
applications comprising multiple motor drives (e.g.
machine tool with up to 8 driving axes with ~10 to
20 m motor cable each)
Broadband filter performance with low frequency
attenuation down to 10 kHz for reliable suppression
of conducted interference in applications with
regenerative motor drives
Slim book-style shape requiring minimum cabinet
space and allowing convenient installation right
beside the motor drive
Touch-safe terminal blocks provide unsurpassed
electrical safety and contacting cross section
according to EN 60204-1 installation standard
For even better filter specifications, please consider

* 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 5.3 times higher levels.
