It sits between the supply and the drive, limiting harmonic distortion and reducing voltage notching on the line. The 0.78 mH inductance at 16.2 A rated current (18 A max thermal) gives a 2% relative inductive voltage drop at rated conditions — that's the figure that governs how much the choke smooths the current waveform. For a 400 V or 480 V three-phase AC supply at 50/60 Hz, this choke is sized for a drive drawing up to about 16 A continuous. The 37 W copper loss plus 15 W iron loss at full load means it dissipates roughly 52 W total; that heat goes into the panel air, so factor it into your enclosure cooling. ## Deployment context IP00 means this is an open-frame component — no enclosure around the windings. The screw-type terminals accept stranded or solid copper; wire size should match the 18 A continuous rating (typically 2.5 mm² or 14 AWG). Dimensions are 148 mm wide, 139 mm tall, 78 mm deep — it fits a standard backplate but occupies a fair footprint; plan the gland plate and DIN-rail layout around it. Thermal class B insulation (130 °C) means the winding hot-spot is rated for that temperature, adequate for a 40 °C ambient with natural convection.","metaTitle":"Siemens 4EP3600-4US00 Mains Choke, 3-Phase, 18A, 0.78 mH","metaDescription":"Siemens 4EP3600-4US00 mains choke for VFD, 3-phase AC, 400/480V, 18A max, 0.78 mH, IP00, screw terminals, active production, UL/CSA recognized.
