The SIDAC 4EU3032-4MB08-0AA0 is a 3-phase filter reactor rated for 85.1 A continuous and 94.5 A maximum, at 440 V AC, 50 Hz. The 5% relative throttling factor (0.65 mH inductance) shapes the harmonic profile on the line side of a drive or power converter — it limits current rise and attenuates the switching noise a VFD feeds back into the plant network. The 302 W power loss at full load tells you what the enclosure has to shed; at IP00 with no enclosure of its own, this mounts inside a panel with forced airflow or derated ambient.
Sizing and thermal class
Rated for 40 °C ambient with Class H insulation (180 °C thermal class per IEC 60085). That headroom means the reactor can handle sustained overloads and higher ambient temperatures inside a crowded cabinet without accelerating insulation aging — the thermal margin is there for the drive's DC-link ripple and harmonic currents, not just the fundamental 85.1 A. The 50 kvar reactive power rating and 223 Hz resonant frequency match this reactor to a specific filter bank design — it is not a general-purpose line reactor. The resonant point sits above the 5th harmonic (250 Hz at 50 Hz fundamental), so it does not amplify the dominant harmonics from a 6-pulse rectifier.
Lifecycle stage is marked mature — the part is in steady production, not newly introduced and not flagged for phase-out. No successor order code is published.
IP00 — no ingress protection — so it must live inside a panel or enclosure. The main circuit terminates on flat connectors or screw-type terminals; plan for busbar or cable lugs sized for 85 A continuous. Dimensions are 0.3 m wide × 0.269 m tall × 0.211 m deep — verify the mounting footprint against your cabinet layout before specifying.
