It is rated for 400 V AC at 50 Hz, with a rated inductance of 1.4 mH and a relative inductive voltage drop of 4% at the measurement level — meaning it introduces a predictable impedance that smooths commutation notches and protects the converter's semiconductor switches from excessive di/dt. The choke carries a thermal continuous current (Ith) of 20 A and a rated current (I LN) of 18 A, with a DC-rated current of 24.5 A. This makes it suitable for line-side or load-side filtering in a 400 V class drive system where the continuous motor current stays at or below 18 A AC. The 1.4 mH inductance at 50 Hz, combined with the 4% voltage drop, gives a predictable impedance that helps meet EMC requirements by limiting high-frequency current ripple. The power loss splits into 39 W in the coil and 9.3 W in the iron core, for a total of 48.3 W at rated conditions — heat that must be accounted for in the enclosure thermal budget. Thermal class B (130 °C) insulation per IEC 60085 means the winding can operate continuously at up to 130 °C hot-spot temperature, with a 40 °C ambient rating. The 3-phase design matches standard 400 V AC drives; the DC current rating of 24.5 A gives headroom if the choke is used on the DC bus rather than the AC line.","metaTitle":"Siemens 4EP3601-0DS00 Commutating Choke, 18A, 400V AC, 1.4mH","metaDescription":"Siemens 4EP3601-0DS00 commutating choke for converter, 3-phase, 18A rated, 400V AC, 1.4mH, IP00, screw terminals.
