Product details

It provides an inductance of 0.3 mH and is designed for AC voltage systems. This component sits between a variable-frequency drive output and the motor cable to limit the rate of voltage rise (dV/dt) and reduce reflected wave peaks on long cable runs — a common failure mode in drive-fed motor windings. The reactor's thermal class H (IEC 60085) rating means its insulation system withstands 180 °C continuous hot-spot temperature. That matters when the 387 W coil losses and 214 W iron-core losses are dissipated in an IP00 enclosure — the part relies on free air convection or cabinet airflow, not sealed cooling. Ambient temperature is rated at 40 °C. Panel builders should account for the total 601 W dissipation when sizing cabinet ventilation.

The reactor measures 0.35 m wide × 0.32 m tall × 0.22 m deep, and the main circuit connects via flat-type terminals. The flat connectors suit busbar or bolted-cable lugs. Verify the available depth in the panel: 0.22 m (220 mm) is the full depth including any mounting base.

This part is classified as mature lifecycle stage. It is not marked as obsolete, but mature status implies stable demand with no active promotion or revision. No official successor part is listed by the manufacturer, so the BOM line stays with this order code unless a parametric substitute is validated against the drive's output requirements.

Frequently asked questions

What does the 4 kHz switching frequency rating mean for my drive selection?

The 4 kHz rating is the reactor's designed switching frequency — it is matched to drives that operate at a 4 kHz PWM carrier. Using this reactor on a drive with a higher carrier frequency (e.g., 8 kHz or 16 kHz) will increase core losses and may cause overheating. The 125 Hz minimum frequency refers to the fundamental motor frequency, not the carrier.
