It delivers 10 kvar of reactive power and uses a 14% relative throttling factor to smooth the harmonic content from a variable-frequency drive's output or input line. The 0.0019 H inductance and 160 Hz resonant frequency are tuned to suppress the dominant harmonics without creating a parallel resonance with the drive's DC-link capacitors — a common failure point when the wrong choke is dropped in. Thermal class B (130 °C rise) per IEC 60085 means it handles the heat from 96.2 W of power loss at full load without derating, as long as the ambient stays at or below 40 °C. The IP00 enclosure is bare — no dust or drip protection — so this lives inside a ventilated cabinet, not out on the plant floor. ## Integration — panel fit and wiring Mounting dimensions are 0.219 m wide by 0.179 m tall by 0.143 m deep. That footprint is larger than a contactor but smaller than a typical line reactor for this kvar class — measure your sub-panel real estate before committing. Main-circuit connections are screw-type terminals, so expect a #10 or M5 ring terminal for the incoming and outgoing phases. No auxiliary control wiring; this is a passive series element. The 3-phase conductors pass straight through; there is no neutral or ground terminal on the reactor itself — bond the cabinet ground per local code.","metaTitle":"Siemens SIDAC 4EP4002-7MS00 Filter Reactor, 27.7A, 210V, 3-P","metaDescription":"Siemens SIDAC 4EP4002-7MS00 3-phase filter reactor. 27.7A rated, 210V AC, 60Hz, 10 kvar.
