It handles a maximum AC current of 280A and a rated AC current of 252A, with a peak current capability of 350A. The inductance is 0.075mH with a relative inductive voltage drop of 4% at rated conditions. This is the line reactor that sits between the converter and the motor or supply, limiting di/dt and reducing harmonic distortion on the DC link. The 280A maximum AC current and 252A rated AC current tell you this choke is sized for a 250–280A drive output, not a 400A frame. The 343.1A DC rated current gives the DC-link side its limit. The IP00 enclosure means it's an open-frame component for cabinet mounting, not standalone outdoor use. Thermal class H (180°C) insulation per IEC 60085 means it can run hot in a crowded panel without derating prematurely. ## What it connects to and how it mounts The 4EU2722-7BA00-0AA0 is an open-frame choke (IP00) designed for bolting into a cabinet or on a mounting plate — no DIN-rail clip here. Dimensions are 0.27m wide, 0.248m high, 0.187m deep. It's built to EN 61558-2-20, the standard for chokes and reactors. The 50Hz rating means it's tuned for 50Hz mains; if your site runs 60Hz, the inductance and saturation behavior shift — verify the application before dropping it into a 60Hz line.","metaTitle":"Siemens 4EU2722-7BA00-0AA0 Commutating Choke, 400V 3-Phase 2","metaDescription":"Siemens 4EU2722-7BA00-0AA0 commutating choke for converter, 3-phase, 400V AC, 280A max AC, 252A rated AC, 0.075mH, IP00.
