ABB 3HAC024322-001 Mains Line Filter, EN 55011 Class A, >40 dB Insertion Loss, 150 kHz–30 MHz

Product Overview

The ABB 3HAC024322-001​ is an OEM-specified three-phase mains line filter (EMI/RFI power-line filter) engineered by ABB Robotics for the IRC5 industrial robot controller platform. It is a passive electromagnetic-compatibility component installed at the main AC power entry of IRC5 Single, Compact, Dual, Paint, Foundry and Panel-Mounted Controller (PMC) cabinets, and its material number—the 3HAC​ prefix—places it squarely in ABB Robotics’ spare-parts numbering system rather than in the drives-and-controls 3BHE​ family. In plain terms, the ABB 3HAC024322-001​ is the metal-cased component that sits between the main switch and the drive rectifier, and it performs a job that no software can: it decides which frequencies get into the cabinet and which stay on the plant bus.

The working principle of the ABB 3HAC024322-001​ is impedance mismatch. For the 50 Hz / 60 Hz fundamental, the series inductors present near-zero reactance and the shunt capacitors present near-infinite reactance, so useful power passes unhindered to the main computer, the axis drive modules, the safety board and the I/O bus. For the high-frequency content generated by the servo drive’s PWM rectification—and for the surges, commutation notches and transients arriving from the plant grid—the common-mode and differential-mode inductors develop large reactive impedance while the Y-capacitors become a low-impedance path to ground. The result is a “low-frequency pass, high-frequency cut-off” characteristic: insertion loss in excess of 40 dB across 150 kHz to 30 MHz, which is precisely the span assessed by EN 55011 / CISPR 11 and by IEC 61000-4-x immunity testing.

What makes the ABB 3HAC024322-001​ more than a generic LC network is the tuning. Its attenuation curve, Y-capacitor values, leakage current and terminal sizing are matched to the Drive Module’s PWM signature (switching in the 4–8 kHz region, with harmonic content extending well into the measured band). A generic replacement may be cheaper, but its leakage current is often 8–12 mA rather than the ABB 3HAC024322-001‘s sub-3.5 mA. In an automotive body shop with six to eight IRC5 cabinets on one 30 mA RCD, that difference is the difference between a stable cell and a nuisance trip at every Tuesday morning shift start. The filter is specified for IRC5 controller option 129-1 (“Prepared for CE labelling”); where CE marking or EU installation applies, a filter is required in each robot cabinet. The ABB 3HAC024322-001​ is therefore not a comfort item—it is the component that lets the line be commissioned, inspected and insured.
