The 0.00061 H inductance and 5.67% relative throttling factor mean it's sized to attenuate harmonic currents from a variable-frequency drive or similar nonlinear load — the 5.67% impedance is a common choice for reducing current distortion without excessive voltage drop at the drive input. The 210 Hz resonant frequency tells you where the filter's impedance peak sits; keep that away from the dominant harmonics to avoid amplification. Thermal class H gives headroom for continuous duty in a 40 °C ambient — this reactor can run hot without cooking its insulation. ## Where and how it mounts IP00 means no enclosure — this is a chassis-mount component for a ventilated cabinet. The 0.27 m width, 0.248 m height, and 0.187 m depth give the panel footprint; terminals are flat connectors with screw-type clamping (free conductor ends per the description). Plan for a minimum clearance around the core for airflow and magnetic-field coupling to adjacent steel. The 87.7 A maximum rating is the short-term overload ceiling — the continuous design point is the 79 A rated value.","metaTitle":"SIDAC 4EU2732-0EA48-4EA0 Filter Reactor, 79A, 400V, 50Hz","metaDescription":"SIDAC 4EU2732-0EA48-4EA0 3-phase filter reactor, rated 79A at 400V AC, 50Hz, 50 kvar.
