It's designed to sit between a variable-frequency drive and the motor, smoothing the voltage spikes from PWM switching so the motor windings see cleaner power — that's the core job of an output reactor (also called an output choke). The IP00 rating means it's open-frame, intended for enclosure mounting where the panel provides the environmental seal; the screw-type and tab terminals on the main circuit make for straightforward field wiring. The 8000 Hz switching frequency rating is the one to watch — it tells you this reactor is built for IGBT-based drives running a typical 8 kHz PWM carrier. If your drive's switching frequency is higher (say 16 kHz), the core losses in this reactor will climb and you'll need to derate the current or pick a reactor rated for that frequency. The 2.3 mH inductance and 3.76% impedance (per the description) give a good balance of harmonic attenuation without dropping too much voltage under load. The 40°C ambient temperature and thermal class B insulation (130°C hot-spot) are standard for general-purpose industrial panels; if your cabinet runs hotter, you'll want to check the temperature rise curve. Mount this reactor between the drive output and the motor cable, as close to the drive as practical. Dimensions are 0.17 m wide, 0.15 m high, and 0.12 m deep, so it's a compact block that fits on a standard mounting plate or DIN-rail bracket (though the screw/tab terminals suggest a plate mount is more typical). The screw-type and tab connections accept ring lugs or fork terminals; strip length and torque follow standard practice for the wire gauge matching 12A.","metaTitle":"Siemens SIDAC 4EP3801-1AK00 Output Reactor, 12A 3-Phase, 800","metaDescription":"Siemens SIDAC 4EP3801-1AK00 output reactor, 3-phase, 12A max, 8000Hz switching frequency, 2.3mH, IP00, screw/tab terminals.
