Product details

The Siemens 4EP3801-4DS00 is a 3-phase commutating choke for converter applications, rated 500V AC operating voltage with a maximum continuous current of 28A and a rated current of 25.2A at 50 Hz.

The 28A maximum / 25.2A rated current at 50 Hz sets the thermal limit for continuous converter-side current. The 500V AC operating voltage covers 400V and 480V line supplies with headroom. DC rated current is 34.3A, so it also handles DC-link applications at that level.

Deployment context

IP00 means no ingress protection — mount this inside a ventilated cabinet or panel enclosure where it's protected from dust and moisture. The 0.153m height, 0.178m width, and 0.12m depth footprint fits standard cabinet layouts; screw terminals accept copper conductors for the main circuit. Thermal class B (130°C insulation system per IEC 60085) means the winding insulation is rated for 130°C continuous, which is typical for industrial chokes in converter duty.
