It is designed to smooth current ripple, limit inrush, and reduce harmonic distortion on the line side of drives and power supplies. The IP00 open-frame construction means it mounts inside a panel or enclosure — not in a washdown or dusty environment. Screw-type and tab terminals accept the main circuit wiring. The 8.1 A rated current at 40 °C ambient (thermal class B per IEC 60085) is the continuous thermal limit. If your drive input current at full load is 8 A or less, this choke has headroom; above 8.1 A you need the next size up. The 6 mH inductance determines the impedance at 50 Hz — about 1.88 Ω per phase — which is typical for a 3–5% line impedance drop on a 400 V system, enough to attenuate most drive-induced harmonics without excessive voltage drop under load. Total power loss is 58.1 W (52.6 W in the coil, 5.5 W in the iron core); that heat must be managed inside the enclosure — factor it into your thermal budget. Mounting dimensions: 0.178 m wide, 0.153 m tall, 0.12 m deep. The IP00 frame means no enclosure — it bolts directly to a mounting plate inside the cabinet. Screw/tab terminals accept lugged or ring-terminal wiring for the 3-phase main circuit. Keep clearance around the coil for airflow; at 58.1 W dissipation the core and winding will run warm. Thermal class B (130 °C) insulation gives the margin before the winding varnish degrades.","metaTitle":"Siemens 4EP3800-0EK00 3-Phase Choke, 8.1A, 6mH, IP00","metaDescription":"Siemens 4EP3800-0EK00 3-phase mains choke, rated 8.1A at 400V AC / 50Hz, 6mH inductance.
