Its 1 mH inductance limits harmonic distortion and inrush current on the line side of a drive or power supply. Rated inductance of 0.001 H (1 mH) with a relative inductive voltage drop of 1.3 % at the measurement level — a typical figure for a line reactor that smooths current without excessive voltage sag under load. ## Thermal and enclosure reality IP00 means no enclosure protection — the choke is an open-frame component intended for mounting inside a cabinet or panel that provides the IP rating. Free cable endings for the main circuit connection, so you terminate directly into your power wiring. Thermal class H per IEC 60085 allows a 180 °C hot-spot temperature, which is standard for high-temp reactor windings. The coil dissipates 123 W and the iron core 98.5 W — total 221.5 W of heat that must be removed by cabinet ventilation or derating at elevated ambient temperatures. Rated ambient temperature is 55 °C; above that, you derate current per the manufacturer's thermal curve (not reproduced here). The 0.225 m width, 0.21 m height, and 0.16 m depth give a compact footprint for a 36 A three-phase reactor.","metaTitle":"Siemens 4EU2552-0AE00-0A Mains Choke, 36 A, 600 V, 1 mH","metaDescription":"Siemens 4EU2552-0AE00-0A mains choke (Netzdrossel), rated 36 A / 600 V AC, 1 mH inductance, 20 Hz.
