It carries a continuous AC current of 100 A maximum and a rated operational current of 90 A, with a peak current capability of 125 A. This part is designed to sit between a converter (VFD) and the AC line, limiting current rise rates (di/dt) and reducing harmonic distortion on the supply. The IP00 rating means it is an open-frame component intended for installation inside a grounded enclosure — not for standalone outdoor or washdown duty.
The 100 A AC maximum current and 90 A rated operational current define the continuous motor-load size this choke can support. For a 400 V three-phase drive, 90 A corresponds roughly to a 55 kW motor under typical duty — the choke must be sized to the drive's line-side current, not the motor's nameplate. The 125 A peak rating handles short-duration inrush or transient events without saturating the core. Power loss splits into 135 W in the coil and 52 W in the iron core, totalling 187 W at rated load. That heat must be managed inside the panel — the ambient temperature rating of 40 °C is the reference point; derating applies above that. Thermal class H (180 °C insulation system per IEC 60085) gives headroom for hot spots in a crowded cabinet.
Physical integration
Dimensions are 0.225 m wide, 0.21 m high, and 0.16 m deep. The main circuit connection uses flat-type terminals (bus-bar style), not ring lugs or spring cages — plan for bolted connections with appropriate copper bus bars. The open-frame IP00 construction means it mounts on a panel backplate inside a grounded enclosure, not on a DIN rail.
