FN3100
Bookstyle EMC/EMI Filter for Motor Drives
3-Phase Filters FN3100

Bookstyle EMC/EMI Filter for Motor Drives
- Exceptional broadband attenuation performance from 10 kHz up to 30 MHz
- Slim and user-friendly book-style design with 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
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 FN 3120 H series from Schaffner
Typical Applications
Conventional motor drives with long motor cables and high interference levels
Four quadrant motor drives and servo drives with energy regeneration mode (in combination with a suitable line reactor or LCL filter)
