It carries a rated current of 0.93A with a maximum of 1.03A and an inductance of 0.795H. The relative inductive voltage drop sits at 89% on the measurement level — that high drop tells you this choke is sized to provide significant impedance, which means it's intended for harmonic mitigation or current-limiting duty in a power circuit, not just a small filter reactor. This choke is IP00 — no enclosure, so it mounts inside a panel or cabinet. The screw-type and tab terminals accept the main current circuit wiring. Coil losses are 38.5W and iron-core losses add 14W, for a total heat dissipation around 52.5W at full load. That's not negligible — the panel designer needs to account for that thermal load in the cabinet ventilation, especially since the choke is IP00 and relies on the surrounding air for cooling. The 0.93A rated current at 600V 60Hz sets the continuous load limit. The 1.03A maximum is the thermal limit — do not size the choke for a motor FLA above 0.93A continuous. The 89% inductive drop means this is not a standard line reactor for general harmonic filtering; it is a high-impedance choke for specialized applications like precharge circuits or current-limiting in low-power drives. If you need a standard 3–5% impedance line reactor for a 1A drive, this is the wrong part.","metaTitle":"Siemens 4EP4005-8DB00 Mains Choke, 600V 60Hz 0.93A 3-Phase","metaDescription":"Siemens 4EP4005-8DB00 mains choke (Netzdrossel), 600V AC, 60Hz, 0.93A rated, 1.03A max, 0.795H, IP00, thermal class B.
