The Siemens SIDAC 4EU3652-0EH00-4BA0 is a three-phase output reactor (output choke) rated for 400 V AC with a maximum continuous current of 184 A at a fundamental frequency of 367 Hz and a switching frequency of 5.82 kHz. The 0.1 mH inductance smooths the PWM output from a drive to limit dv/dt and reduce motor bearing currents — a standard fit for longer motor cable runs or when the drive and motor are separated by more than the drive manufacturer's recommended distance.
Sizing and thermal class
Rated ambient temperature is 40 °C with Class H insulation (180 °C thermal class per IEC 60085), so it handles sustained overloads without derating in a warm cabinet. The 166 A rated current (I LN) gives a real-world continuous rating below the 184 A maximum — size your drive's continuous output current against the 166 A figure, not the peak.
IP00 open-chassis design — no enclosure, no drip shield. Mount it inside a panel with clearance around the core for airflow; the flat-type terminals accept busbar or lug connections for the main circuit. Dimensions: 0.35 m wide, 0.32 m high, 0.22 m deep. That's a substantial block — plan for a dedicated mounting plate or DIN-rail bracket if the panel layout allows.
