What this choke is and where it runs
It carries a maximum continuous current of 547 A and a rated current of 492.3 A, with an inductance of 0.000025 H (25 µH) and a relative inductive voltage drop of 2.62% at rated conditions. That 2.62% drop is a typical value for a line reactor sized to limit harmonic distortion and di/dt stress on the converter's input rectifier — not a tuning choke for a drive output, but a line-side smoothing element.
Thermal and environmental limits
Thermal class H (IEC 60085) means the coil insulation withstands 180 °C hot-spot temperature — essential for a choke pulling 230 W of copper loss plus 80 W of iron-core loss at rated load. The ambient temperature rating of 40 °C is the reference; above that the current must be derated per the manufacturer's curve, which is typical for any IP00, open-frame reactor. IP00 means no ingress protection — this choke belongs in a clean, dry, ventilated enclosure, not on a washdown line or outdoors.
Physical fit and connection
Dimensions are 0.3 m wide × 0.269 m high × 0.211 m deep — roughly the footprint of a small suitcase. The main current circuit uses flat-type terminals (bus-bar or cable-lug connection), not screw-clamp or spring-cage. That means the panel builder needs to plan for bolted connections with appropriate lug size and torque, not a DIN-rail terminal block. The choke is not designed for snap-on DIN mounting; it is a chassis-mount or bolted-to-subplate component.
Standard compliance
The design follows EN 61558-2-20, the safety standard for small transformers and chokes. That covers dielectric strength, creepage distances, and thermal endurance. No UL or CSA listing is stated in the evidence, so for North American installs the integrator should verify local code acceptance or request the UL-recognized variant.
