Description
The 3HAC024322-001 is a three-phase mains line EMI filter manufactured by ABB, positioned at the power-entry point of IRC5 Standard and Compact robot controller cabinets and also specified on select ACS350/ACS880 drive incomers. It houses a multistage LC network that simultaneously suppresses common-mode and differential-mode noise—both the grid-borne hash coming in and the dv/dt switching harmonics the drive/servo pushes back onto the mains—keeping the cabinet’s conducted emission below EN 61800-3 Category C3 and EN 55011 Class A thresholds so the line can clear automotive-plant or semiconductor-fab EMC audits without drama.
h2 Application Scenarios
In a body-shop welding cell running eight IRB 6700 robots on a 400 V / 63 A riser, the integrator initially powered the IRC5 cabinets straight off the machine-side distribution board—no line filter, “just a breaker and a contactor.” The cell passed cold-commissioning, but when all eight robots fired spot-welds in sync during a production trial, the adjacent vision-inspection cabinet (third-party GigE cameras on the same 400 V feeder) began dropping frames every weld cycle. Portable EMI sniffing showed 150 kHz–10 MHz conduction spikes riding the neutral, traced back to the IRC5 servo regen path. The retrofit bolted a 3HAC024322-001 (63 A / 400 V version) into each IRC5 cabinet’s main-incomer slot, landed L1/L2/L3/N/PE on the screw terminals, and tied the filter’s metal flange to the cabinet’s PE bar with a short braid. Post-retrofit, the vision-camera CRC-error count dropped from ~40 per shift to zero, and the plant’s third-party EMC survey signed off at 6 dB below the C3 limit—no software change, no rewiring beyond the filter landing. For any IRC5 cell sharing a feeder with sensitive metrology or neighboring PLC racks, the 3HAC024322-001 is the 20-minute hardware fix that prevents “it’s a software bug” wild-goose chases.

h2 Technical Principles and Innovative Values
Innovation Point 1: Dual-Mode LC Suppression in One Metal Can. Most off-the-shelf filters pick a lane—either common-mode (Y-cap + CM choke) for grid noise, or differential-mode (X-cap + DM choke) for load-side switching hash. The 3HAC024322-001 stacks both into a multistage ladder: CM chokes catch the PE-referred noise that tries to ride the motor-cable shield back onto mains, while DM stages tame the L-N and L-L switching spikes from the IRC5 servo drives during regen. One box, both directions.
Innovation Point 2: C3-Class Conformance Tuned for Industrial Robots. EN 61800-3 Category C3 is the “industrial environment” tier—less forgiving than C4 (process plants) but tighter than C2 (plug-in tooling). The 3HAC024322-001 is tuned so that an cabinet with this filter at the inlet will typically land 6–10 dB below the C3 limit line across 150 kHz–30 MHz without additional ferrite or screened cable trays. That margin is what lets a body shop pass EMC without re-engineering the whole feeder.
Innovation Point 3: PE-Dependent Shielding Architecture. The metal housing isn’t cosmetic—it’s part of the filter’s return path. When the 3HAC024322-001 is bolted to a properly grounded cabinet back-panel and the PE terminal sees < 0.1 Ω back to the building earthing grid, the shield continuity holds insertion loss steady even with adjacent 200 A welder feeders two inches away in the same trunking. Skip the PE braid, and those 40 dB numbers on the datasheet evaporate—ABB’s own install note (3HAC043897-001 lineage) is explicit on this.
Innovation Point 4: Natural-Convection Longevity. No fan, no active parts—just wound toroids and film caps rated for the –25 °C to +55 °C swing of a robot cell next to a weld gun. In a 24/7 body shop the 3HAC024322-001 typically runs 8+ years without intervention, which is why it’s rarely stocked until the day an EMC audit fails and someone realizes the original was “optional” on the BOM.
h2 Application Cases and Industry Value
A beverage-can printing line retrofitting six paint-robot stations to a new 800xA MES had to re-certify EMC because the old filters were “generic brand X” that didn’t quite hold C3 once the new 400 V feeder shared a tray with a 315 kW main-drive VFD. The maintenance lead swapped all six incomers to ABB 3HAC024322-001 (32 A / 250 V version, matching the site’s 230 V distribution) during a single weekend outage. Conducted-emission re-test showed the worst channel at –4 dB relative to C3 limit (previous best with brand X was +2 dB—a fail). More tangibly, the line’s “mystery servo-fault” tickets—three per month where an logged a spurious DC-bus-undervoltage during a neighboring VFD start—dropped to zero over the next quarter. The plant standardized the 3HAC024322-001 as the mandatory inlet filter on all future installs, and cut the stores “generic EMI filter” SKU entirely.
h2 Related Product Combination Solutions
The 3HAC024322-001 sits at the cabinet inlet, so its natural companions are the modules downstream on the same 24 V / 400 V rails:
- SD834: 24 V DC DIN-rail PSU inside the that feeds the DSQC I/O and safety modules—the 3HAC024322-001 cleans the 400 V upstream so the SD834’s input stage sees less dv/dt.
- CI854AK01 / PM891: From earlier in this series—when the cell reports into an 800xA DCS, the CI854AK01 Profibus master and PM891 CPU sit in a neighboring cabinet whose own 24 V rail benefits from clean mains upstream.
- ACS880: ABB’s MV drive series—many ACS880 starter kits list the 3HAC024322-001 (63 A version) as the recommended inlet filter when the drive shares a feeder with sensitive instrumentation.
- 3HAC-series Drive / DSQC modules: The internal servo drives and DSQC I/O slices are the actual noise generators the 3HAC024322-001 is defending the grid against—and protecting, in reverse, from grid-borne surges.
- XVD825A01 (3BHE015619R0001): The triple-protocol interface board from the earlier product—if the cell also hosts a Symphony Plus gateway in the same room, the 3HAC024322-001 at the robot inlet keeps the XVD825A01’s Ethernet/RS485 side quieter.
