At 61 W power loss and thermal class B (IEC 60085), it's built for continuous duty inside a panel — IP00 means it needs an enclosure for anything beyond a clean, dry electrical room. The screw-type and tab terminals accept common lug or ring connectors, so it wires in like any standard line reactor. Rated 6.92 A at 400 V AC — that's the continuous current it can carry without exceeding the 40°C ambient rise. The 7.69 A maximum gives a short-term headroom for overload transients, but the steady-state load should stay at or under the 6.92 A figure. Inductance of 0.017 H with 14% throttling means it's tuned for typical variable-frequency drive input harmonics; the 134 Hz resonant frequency keeps it out of the way of the 50 Hz fundamental and the common switching bands. Reactive power of 5 kvar tells you the volt-amp reactive it exchanges with the line — useful for sizing upstream protection. ## Where it goes in a panel At 178 mm wide, 153 mm tall, and 120 mm deep, it takes up a modest footprint on a subplate or DIN-rail mount (though the IP00 rating and screw/tab terminals suggest a bolted-down installation rather than a snap-on rail). The 61 W heat dissipation needs to be factored into the enclosure's thermal budget — plan for airflow or derating if the ambient inside the cabinet runs above 40°C. The screw-type and tab terminals accept conductors up to what a standard line reactor of this current class handles; no special tooling needed.","metaTitle":"Siemens SIDAC 4EP3801-1MS00 Filter Reactor, 6.92 A, 0.017 H","metaDescription":"Siemens SIDAC 4EP3801-1MS00 3-phase filter reactor, 400 V AC, 6.92 A rated, 0.017 H, 14% throttling, IP00.
