Product details

The Siemens 4EU4321-6DA00-0A is a 3-phase commutating choke for converter applications, rated for 720 A continuous with a maximum of 800 A and a peak current capability of 1 000 A. It operates at 750 V AC, 50 Hz, and carries an inductance of 0.000055 H.

Sizing and thermal reality

Total power loss at rated load is 480 W coil plus 285 W iron core. At IP00, heat dissipates into cabinet air — plan forced ventilation if ambient exceeds 40 °C.

This part carries a mature lifecycle status.

Physical fit and connections

Dimensions: 0.46 m wide × 0.435 m high × 0.265 m deep. Main circuit connections are flat-type terminals. IP00 rating means no integral enclosure.

Frequently asked questions

What approvals does 4EU4321-6DA00-0A carry?

The listing notes UL/CSA recognition per EN 61558-2-20. That covers the safety standard for chokes and transformers in North American and European installations.
