Features and Benefits

FN 3840 series of filters provides state-of-the-art EMI attenuation based on an innovative filter topology. They help to ensure compliance with Class C2 or even C1 limits.
The filters are built to fit perfectly to regenerative drive applications with LCL filters
Internal thermocouples ensure reliability and thermal shutdown capabilities
The slim book-style shape allows a convenient and space-saving installation next to inverters, converters or motor drives.
The filters offer very high saturation performance, bundled with best EMI performance
Fulfills the requirements in IEC/EN 61800-5-1 for electric strength, clearance and creepage
Fulfills the requirements in IEC/EN 60204-1 for insulation resistance, electric strength, clearance and creepage
Fulfills the requirements in IEC/EN 62477-1 for electric strength, clearance and creepage
