Rated for 3-phase 400 V AC at 50 Hz, it carries a continuous 50 A line current (61.2 A DC equivalent). The 0.588 mH inductance and 4% relative inductive voltage drop at rated current are the key numbers for sizing: that 4% drop means the choke will absorb about 4% of the line voltage at full load, which is typical for a 4% impedance reactor. The 51 W coil loss plus 30 W iron core loss (total 81 W at 50 °C ambient) must be ventilated — IP00 open-frame construction means it needs clearance and airflow in the enclosure; no washdown or dust rating here. Dimensions: 0.219 m wide, 0.179 m tall, 0.143 m deep. IP00 means it is an open-frame component: mount it inside a ventilated cabinet, away from dust and moisture. The thermal class B (130 °C) insulation system handles the 81 W total loss at 50 °C ambient; derate the continuous current if ambient exceeds that. No DIN-rail clip — this is a panel-mount reactor, typically bolted through its base plate.","metaTitle":"4EP4010-0KS00 Siemens Commutating Choke, 50 A, 3-Phase, 400","metaDescription":"Siemens 4EP4010-0KS00 commutating choke for converter, 3-phase, 50 A rated, 400 V AC, 50 Hz, IP00, UL/CSA recognized.
