It sits between the AC line and the drive input, limiting current rise rates and reducing harmonic distortion. Rated for 400 V AC at 50 Hz, it handles a maximum AC current of 18 A and carries a rated inductance of 1.2 mH (1.24 mH per the description). Three key numbers decide whether this choke fits your drive line: the AC current rating (18 A maximum), the inductance (1.2 mH), and the voltage drop (4%). The 18 A AC maximum is the thermal limit for continuous operation at 40 °C ambient — if your drive draws more than 18 A continuous, step up to a higher-rated reactor. The 1.2 mH inductance determines the impedance at 50 Hz (about 0.38 Ω); this is what limits the inrush and shapes the line current. The 4% voltage drop is typical for a line reactor sized to the drive's nominal current — it provides enough impedance to reduce harmonics without dropping too much voltage under load. The choke also carries a peak current rating of 23 A and a DC rated current of 22 A, which are surge and short-duration limits, not continuous ratings. Power loss is split between the coil (39 W) and the iron core (7 W), for a total of 46 W at rated load. The thermal class is B (130 °C rise) per IEC 60085, which is standard for dry-type reactors in industrial panels. This is a panel-mount component. Dimensions are 0.148 m wide, 0.126 m tall, and 0.078 m deep. That's about 5.8 x 5.0 x 3.1 inches, so it fits on a standard DIN-rail mounting plate or directly on a back panel. Leave clearance around it for airflow; the 46 W heat dissipation needs ventilation, not tight enclosure against other heat sources. The IP00 protection class means no gasket or sealed housing — keep it dry and clean inside the cabinet.","metaTitle":"Siemens 4EP3601-4DS00 Commutating Choke, 3-Phase 400V 50Hz 1","metaDescription":"Siemens 4EP3601-4DS00 commutating choke for converter. 3-phase, 400V AC, 50Hz, 18A max AC, 1.2mH.
