FB-40250A - 250A EMC Line filter for CIMR-AC4A0208AAA, CIMR-AC4A0250AAA
MPN: FB-40250A
Alt. SKU: 10002297
Why Choose the Yaskawa FB-40250A EMC/RFI Filter?
The Yaskawa FB-40250A is a heavy-duty EMC / RFI input filter designed for compatible Yaskawa A1000 AC inverter drives. Installed between the incoming mains supply and inverter input terminals, it helps suppress conducted electromagnetic interference generated by variable frequency drives, supporting improved EMC compliance and reliable operation of surrounding automation equipment.
Designed for 380–480 V three-phase systems with a 250 A current rating, the FB-40250A is typically used with larger A1000 inverter models controlling motors from approximately 90 kW heavy duty up to 132 kW light duty.

What Does an EMC Filter Do?
Variable frequency drives generate high-frequency switching signals that can introduce electrical noise into the incoming power network. The FB-40250A attenuates this conducted interference before it reaches the mains supply, helping reduce disruption to PLCs, sensors, communication systems and other nearby electronic equipment.
Typical Applications
- Yaskawa A1000 inverter installations.
- High-power 400 V three-phase motor control systems.
- Industrial automation and production equipment.
- Material handling and conveyor systems.
- Packaging and manufacturing machinery.
- Installations requiring EMC compliance.
