The 22-RF021-BL external EMC/RFI line filter by Allen Bradley is intended for use with PowerFlex 4M drives. This unit is designed to mitigate electrical noise generated by variable frequency drives (VFDs) on power lines, thereby enhancing electromagnetic compatibility (EMC). With a voltage input specification of 200 to 240 volts AC, it effectively supports 3-phase configurations. This filter can handle a continuous current rating of 21 amps and is compatible with power outputs up to 3.7 kilowatts (or 5 HP).

Constructed within an IP20-rated enclosure, the filter is suitable for open-type applications, assuring adequate protection against personal injury. The unit is designed to be mounted on a panel for ease of installation. Featuring a long cable with an L-type configuration, it accommodates various cable routing requirements effectively.

The 22-RF021-BL meets several important compliance standards including CE, UL, and RoHS, ensuring compatibility with international safety and environmental regulations. Additionally, the device demonstrates excellent insulation properties with resistance greater than 100 mega ohms at 500 volts DC, enhancing its reliability. This product operates well in environments with a maximum relative humidity of 80% RH (non-condensing), making it a practical choice for many industrial settings.
