What it is and what it does
The SIDAC 4EP3800-8MS00 is a 3-phase filter reactor rated for 400 V AC at 50 Hz, with a rated current of 9.8 A and a maximum current of 10.9 A. It provides 6.2 kVAR of reactive power and an inductance of 0.0049 H, with a relative throttling factor of 5.67%. The part is designed to attenuate harmonic distortion and limit inrush current in power systems, with a resonant frequency of 210 Hz and a power loss of 62 W at rated conditions. Thermal class B per IEC 60085 means the winding insulation withstands a 130 °C hot-spot temperature — standard for general-purpose industrial reactors. IP00 protection means it is an open-frame component intended for installation inside an enclosed panel or cabinet — not for direct exposure to dust or moisture.
Integration notes
Dimensions are 0.178 m wide × 0.153 m high × 0.12 m deep. The open-frame design (IP00) means it must be mounted inside a panel with adequate clearance for airflow — the 62 W power loss needs ventilation or forced cooling in a sealed enclosure. Screw-type terminals for the main circuit accept standard power wiring. Wire the three phases in series with the load; the reactor is not polarity-sensitive.
