It's rated for a maximum continuous current of 33 A at a rated frequency of 8000 Hz, with an inductance of 0.16 mH. This part sits between the drive output and the motor cable to limit dv/dt and reduce motor bearing currents — a standard fit for long cable runs or multiple motors on one drive. The 33 A maximum current (Ithmax) at 8000 Hz switching frequency tells you this reactor is sized for a drive output stage that switches at 8 kHz carrier. The 0.16 mH inductance (LN) and 13.1% impedance (UK) are tuned to that frequency — it's not a general-purpose 50/60 Hz line reactor. The 48.5 W coil loss and 27 W iron loss give you the thermal budget for enclosure sizing; at 40 °C ambient and thermal class B (130 °C rise limit), you've got headroom for a 50 °C cabinet if you derate. IP00 means no enclosure — this is a panel-mount component that needs a cabinet or cubicle for touch protection and dust ingress. Screw-type terminals accept standard power cable lugs; no special crimp tooling required. Dimensions: 0.17 m wide, 0.15 m high, 0.12 m deep. Mounting is via the core frame; no DIN rail adapter. Plan for screw-terminal access on the main circuit connection side.","metaTitle":"Siemens 4EP3800-1QS00 SIDAC Output Reactor, 33A, 8000 Hz","metaDescription":"Siemens 4EP3800-1QS00 SIDAC output reactor, 3-phase, 33A max, 8000 Hz rated frequency, 0.16 mH, IP00, screw terminals.
