It delivers an inductance of 0.51 mH with a relative inductive voltage drop of 5 % — that 5 % figure is what limits harmonic distortion and smooths the DC bus on the drive input. The 161 W coil loss and 136 W iron-core loss add up to 297 W total heat that has to leave the panel; at IP00 with no enclosure, you mount this in a ventilated cabinet or a dedicated choke bay where that heat can rise out. ## Sizing and thermal class Thermal class H per IEC 60085 means the winding insulation handles a 180 °C hot-spot temperature — that's the margin that keeps this choke alive when the drive is pulling hard and the ambient in the cabinet hits 40 °C (the rated ambient temperature). The 86 A maximum is the thermal limit at that ambient; if your drive cabinet runs hotter, you derate. The 77.4 A rated current is the continuous line-side current you size the feeder and fusing for. Flat-type terminals on the main circuit — that means bus-bar or crimp-on ring lugs, not screw-clamp wire ends. The footprint is 0.27 m wide by 0.248 m tall by 0.208 m deep; it's a substantial block that bolts into the panel floor or a mounting plate. IP00 means no drip shield, no finger-safe cover — this lives inside a locked cabinet, not out on the plant floor where washdown or dust could reach it.","metaTitle":"Siemens 4EU2722-0FG00-0AA0 Mains Choke, 86A, 575V, IP00","metaDescription":"Siemens 4EU2722-0FG00-0AA0 mains choke for variable-frequency drives. 3-phase, 575V AC, 86A max, 77.4A rated, 0.51 mH, IP00.
