What this reactor does on the line side
The Siemens SIDAC 4EU3632-4MA08-0AA0 is a three-phase filter reactor rated for 400 V AC at 50 Hz, with a maximum continuous current of 161 A and a rated operating current of 145 A. The 7% relative throttling factor means it drops roughly 7% of line voltage at rated current — typical for harmonic mitigation and motor-drive input protection. The 189 Hz resonant frequency places the trap below the 5th harmonic (250 Hz at 50 Hz fundamental), so it attenuates the dominant 5th and 7th harmonics from a six-pulse drive. Power loss runs 368 W at full load, which drives the ventilation requirement in an enclosure. Thermal class H insulation (180 °C continuous) means the core and windings can run hot without degrading the varnish — important when the reactor shares a panel with drives that dump heat. The 100 kvar reactive power rating of the associated filter bank tells you this reactor is sized for a capacitor bank of that rating, not a standalone line choke. It's a detuned reactor for a power-factor-correction or harmonic-filter bank, not a general-purpose input reactor.
Mounting and terminal reality
IP00 means no ingress protection — open frame, no enclosure. It's designed for inside a panel or cabinet where the environment is controlled. The 0.227 m depth, 0.35 m width, and 0.321 m height give you the footprint for gland-plate planning and DIN-rail or base-plate mounting. Main circuit connections are flat connector / screw-type terminals. That's a lug-style interface — expect ring or fork terminals on the cable ends, not spring-cage or push-in. Verify the lug width matches the terminal bar before terminating.
