FB-40072A - 72A EMC Line filer for CIMR-AC4A0072AAA

Why Choose the Yaskawa FB-40072A EMC/RFI Input Filter?

The Yaskawa FB-40072A is a high-capacity EMC/RFI input line filter designed for use with Yaskawa A1000 series inverter drives. Installed between the incoming mains supply and the drive input terminals, this filter suppresses conducted electromagnetic interference generated by variable frequency drives, helping installations meet industrial electromagnetic compatibility standards.

Variable frequency drives generate high-frequency switching noise which can propagate through the electrical supply network and affect nearby automation equipment. The FB-40072A attenuates these disturbances at the inverter input, improving reliability of PLCs, sensors and control electronics connected to the same power system.

Rated for three-phase 380–480 V systems up to 72 A, this EMC filter is typically used with larger A1000 inverter drives controlling motors up to approximately 30 kW heavy duty or 37 kW light duty. Its panel-mount industrial design allows straightforward installation inside electrical control cabinets.
