The Siemens SIDAC 4EP3800-6MS00 is a 3-phase filter reactor rated 6.9 A (max 7.4 A) at 400 V AC, 50 Hz, with 0.017 H inductance and 14% relative throttling factor. It's designed to sit between a variable-frequency drive and the motor — the 14% impedance limits harmonic currents and protects the drive DC bus from line notching. The 5 kvar reactive-power rating tells you the reactor can handle the magnetizing current of a motor load in that power band. Thermal class B (130 °C rise) per IEC 60085 means it's rated for continuous duty in a 40 °C ambient without forced cooling.
Integration Notes
IP00 — no enclosure, so it mounts inside a panel or cabinet, not in a washdown area. The screw-type and tab terminals accept standard ring lugs or fork terminals for the main circuit. Dimensions 0.178 m wide × 0.153 m high × 0.12 m deep — fits a standard backplate footprint. The 61 W power loss at rated load means it will heat the enclosure; account for that in your thermal budget if the cabinet is densely packed.
Compliance & Approvals
Built to EN 61558-2-20 (safety of transformers, reactors, and power supply units) and carries UL/CSA recognition — the nameplate marking is the authority signal for North American panel acceptance. The resonant frequency of 135 Hz means the series-resonant point is well above the 50 Hz fundamental and below typical PWM carrier frequencies, so it won't create a low-impedance trap at the switching frequency.
