Product details

It carries a continuous rated current of 50.4 A with a maximum of 56 A, and a DC-rated current of 68.6 A. The inductance is 0.25 mH, with a relative inductive voltage drop of 2% at rated conditions.

The choke is open-frame (IP00), so it must be installed inside an enclosure that provides the required touch protection and environmental sealing. Connections are via screw-type terminals sized for the main circuit. Thermal class B (130 °C) per IEC 60085 governs the insulation system; total power loss is 62 W (50 W coil + 12 W iron core) at the rated 40 °C ambient. Panel builders should account for this heat dissipation when sizing ventilation.

Physical dimensions: 0.178 m wide × 0.153 m high × 0.105 m deep. The 2 % voltage drop at rated current and frequency is a key parameter for coordination with the converter's DC-link design — it affects the available DC bus voltage under load.
