What this filter reactor does and where it fits
The SIDAC 4EU2732-0MF08-0AA0 is a 3-phase filter reactor rated for 71 A continuous (78.9 A maximum) at 415 V AC, 50 Hz, delivering 50 kvar of reactive power. The 7 % relative throttling factor and 0.83 mH inductance are sized to suppress harmonic currents from variable-frequency drives and other non-linear loads, protecting upstream capacitors and transformers. The 189 Hz resonant frequency means it's tuned for the 3rd and 5th harmonic range typical of 6-pulse rectifiers. With IP00 protection, this is an open-frame component intended for installation inside a ventilated enclosure or panel — not for washdown or outdoor exposure. Thermal class H insulation (rated for 180 °C continuous) gives headroom in high-ambient cabinets up to 40 °C.
Termination and panel integration
Main circuit connections use flat-type terminals with screw clamping — typical for busbar or cable-lug termination in power distribution panels. The 0.27 m width and 0.248 m height footprint fits a standard sub-panel or backplate layout; the 0.187 m depth must be accounted for in enclosure depth clearance, especially when mounted near gland plates or door-mounted components. IP00 means no ingress protection — keep clearance from live parts per local wiring regulations and ensure the enclosure provides the required IP rating for the environment.
