It provides 0.0035 H of inductance per phase, sized to limit voltage spikes and reduce capacitive charging currents on long motor cable runs from a PWM drive. The 49.6 W coil loss and 29.4 W iron-core loss (total ~79 W) at rated load mean the panel needs to shed that heat — mount with clearance for natural convection, not buried against other heat sources. The 3000 Hz rated frequency tells you this reactor is designed for high-switching-frequency drives — typical IGBT PWM outputs at 3–4 kHz. A standard 50/60 Hz line reactor would saturate at those frequencies; this one's core material and air gap are tuned for the higher harmonic content. The 6.1 A maximum current (with a 5.5 A rated continuous current per the description) matches a 2.2–3 kW drive output on 400 V class. Thermal class B (130 °C rise) per IEC 60085 means the winding insulation handles the extra heat from the high-frequency iron losses without derating — important when the reactor is in a closed cabinet. Mounts between the drive output and the motor cable. IP20 means it is for inside the enclosure only — no washdown, no dust-laden air. The screw-type and tab terminals accept cable lugs or fork terminals; the tab connection is useful for a quick bus-bar link in a multi-axis cabinet. Dimensions 0.17 m wide × 0.15 m high × 0.1 m deep — fits a standard 200 mm deep enclosure with room for wiring clearance at the terminals.","metaTitle":"Siemens SIDAC 4EP3701-3UP00 Output Reactor, 6.1A, 3000Hz","metaDescription":"Siemens 4EP3701-3UP00 SIDAC output reactor, 3-phase, 6.1A max, rated 3000Hz, 0.0035H, IP20, screw/tab terminals.
