The 8000 Hz switching frequency rating tells you it's designed for the output of a PWM drive — it's there to smooth the motor current waveform, limit voltage spikes, and reduce bearing currents on long cable runs. The 0.0003 H (0.3 mH) inductance per phase is the value that governs how much common-mode and differential-mode noise it filters. The IP00 protection class means it's an open-frame component — no enclosure. The flat-type terminals are for bolted bus-bar or cable-lug connections, not spring-cage or screw-clamp wiring. The thermal class H insulation system handles winding temperatures up to 180 °C, so it can live near a hot drive without derating prematurely. This reactor mounts between the drive output and the motor terminals. The 0.46 m width and 0.43 m height give you the panel footprint — it's not a DIN-rail part; you'll bolt it to a backplate or mounting rail. The 0.26 m depth means you need that much clearance behind the panel door for the winding body and terminals. Plan for adequate ventilation around it — the 40 °C ambient rating is the maximum surrounding air temperature for full-current operation without forced cooling.","metaTitle":"SIDAC 4EU4321-0EH00-0A Output Reactor, 110A 3-Phase AC","metaDescription":"SIDAC 4EU4321-0EH00-0A output reactor (choke) rated 110A max, 3-phase AC, 8000 Hz switching frequency, IP00.
