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.","metaTitle":"Siemens 4EP3801-4DS00 Commutating Choke, 28A, 500V, 3-Phase","metaDescription":"Siemens 4EP3801-4DS00 commutating choke for converters. 28A max, 500V AC, 3-phase, 0.0013H, IP00, screw terminals.
