Product Overview

The Allen-Bradley 22F-RF021-BL is an S-Type EMC/RFI line filter kit designed to suppress electromagnetic interference on input mains lines for PowerFlex 4M Adjustable Frequency AC Drives. Engineered for 240V AC, 3-phase systems operating at 50/60 Hz with a rated current of 21 Amps, this filter is optimized for motor drives rated from 2.2 kW to 5.5 kW (with overall drive series compatibility spanning 0.2 kW to 5.5 kW). By mitigating high-frequency electrical noise and harmonic feedback, the 22F-RF021-BL protects surrounding automation equipment and ensures compliance with international electromagnetic compatibility (EMC) standards across industrial pump, fan, and conveyor applications.

Key Operational Features

  • Effective Noise Suppression: S-Type filter design attenuates radio frequency interference (RFI) and high-frequency emissions caused by drive PWM switching.
  • Optimized for 240V 3-Phase Systems: Provides high attenuation across 3-phase 240V power networks up to a continuous current draw of 21A.
  • Broad System Compatibility: Integrates smoothly with standard 3-phase induction motors driven by the PowerFlex 4M AC drive family.
  • Extended Thermal Thresholds: Designed for robust industrial panel deployment across ambient operating temperatures from -20°C to 60°C.

Installation & Field Wiring Guidelines

1. Physical Mounting: Mount the EMC filter directly adjacent to or beneath the PowerFlex 4M drive to minimize wiring distance and noise radiation.

2. Power Terminal Connections: Connect the 240V 3-phase AC power input lines to the line side of the filter, and connect the filter's output terminals to the drive input power terminals.

3. Grounding & Cabling: Establish a low-impedance ground connection between the filter chassis and protective earth (PE) bus, and utilize recommended conductor wire sizes to avoid excessive voltage drops.

Frequently Asked Questions (FAQs)

Q1: What power drive range is compatible with the Allen-Bradley 22F-RF021-BL filter?
A1: The filter operates optimally for PowerFlex 4M drives in the 2.2 kW to 5.5 kW range on 240V 3-phase lines, with general series integration supported from 0.2 kW to 5.5 kW.

Q2: What electrical ratings apply to the 22F-RF021-BL line filter?
A2: It is rated for 240V AC, 3-phase, 50/60 Hz systems with a maximum continuous current of 21 Amps.

Q3: Why is installing an EMC filter like the 22F-RF021-BL necessary?
A3: It suppresses conducted electromagnetic interference (EMI) back onto the utility power line, preventing disruption to sensitive control electronics and sensors on the same grid.
