What this 3-phase filter reactor is and where it lands in the panel
The SIDAC 4EU2732-8MA08-4CA0 is a 3-phase filter reactor rated for 41.5 A continuous at 400 V AC, 50 Hz. It carries a 14 % relative throttling factor and an inductance of 0.0028 H, sized to attenuate harmonic currents from variable-frequency drives or other non-linear loads upstream of the line. The IP00 enclosure means it is an open-frame component intended for installation inside a grounded cabinet — no touch protection on the core or windings, so the panel builder must provide the barrier or clearance. Connection is via flat-type terminals (screw termination), which mate with standard busbar or cable lugs in a distribution section.
What the ratings mean for fit — the so-what on current, voltage, and thermal class
The 41.5 A rated current is the continuous RMS value the reactor can carry at 40 °C ambient without exceeding the H-class insulation temperature rise. The maximum current of 46.2 A is the overload ceiling.
Mounting and integration — what the panel builder needs to know
The reactor occupies a footprint of 0.27 m wide by 0.248 m tall by 0.187 m deep. It is an open-frame (IP00) component, so it must be mounted inside a grounded metal enclosure.
