It handles a maximum continuous current of 31.5 A, with a rated current of 28.35 A — the figure to use for continuous-duty sizing. The 0.89 mH inductance and 4% relative inductive voltage drop define the impedance it presents to the drive's switching harmonics.
The 31.5 A maximum (28.35 A rated) sets the load side: this choke sits between the converter and the motor or between the line and the converter, sized for the continuous RMS current the drive draws. The 4% voltage drop at rated current is the design target — it limits di/dt and reduces harmonic distortion without dropping excessive voltage under load. The 0.89 mH inductance is the actual winding value; higher inductance gives more smoothing but more voltage drop. Thermal class B per IEC 60085 means the winding insulation withstands 130 °C continuous hot-spot temperature. The 18 W coil loss and 19.7 W iron-core loss (37.7 W total at rated conditions) must be dissipated; at IP00 with no enclosure, free-air mounting in a ventilated cabinet is expected. The 40 °C ambient rating is the standard test condition — derate for higher ambient or enclosed mounting. The IP00 protection class means no dust or moisture ingress protection — install inside a panel with at least IP54 enclosure rating.
Physical footprint: 0.097 m wide, 0.111 m tall, 0.115 m deep. This is a compact block-style choke; it mounts via the core bolt or a bracket to the backplane. The 0.115 m depth (115 mm) means it will not fit a shallow 100 mm enclosure — allow at least 150 mm clearance for wiring and airflow.
Designed and tested to EN 61558-2-20, the safety standard for chokes and reactors. Thermal class B per IEC 60085. No UL or CSA listing appears on the record — verify with the factory if a UL-recognized component is required for the panel.
