Product details

The Siemens 4EP3801-7DS00 is a three-phase commutating choke for converter applications, rated at 500 V AC and 25.2 A continuous (28 A maximum, 35 A peak). It's built for line-side or DC-link duty where you need to limit current rise and reduce harmonic distortion on the supply — a common spec for variable-speed drive input stages and regenerative converters.

The 4EP3801-7DS00 is an open-frame (IP00) component — no enclosure, no touch protection. Dimensions are 0.178 m wide by 0.153 m tall by 0.12 m deep; factor that into your DIN-rail or chassis-mount layout. Thermal class B (130 °C) insulation per IEC 60085, with a coil power loss of 52.8 W and iron-core loss of 13.7 W at rated conditions — that's about 66.5 W total heat to vent inside the enclosure.

Rated for a 40 °C ambient with a 50 Hz operating frequency. Off-state leakage and saturation behavior are governed by the 1 mH inductance and the 4% voltage drop spec; for a quick check, that drop at 25.2 A and 500 V is within typical line-reactor design margins.
