FU), 3-phase, 500 V AC, 31.95 A rated / 35.5 A max, 50 Hz, 4% voltage drop, IP00, screw terminals.","salesMarkdown":"## What this choke does for a drive line The Siemens 4EP4001-0US00 is a three-phase mains choke (line reactor) sized for variable-frequency drive inputs. It sits between the supply and the drive rectifier, limiting harmonic distortion and reducing peak currents that stress the DC bus capacitors. Rated 31.95 A continuous with a 35.5 A maximum, it handles the nominal current of a typical 15–18 kW motor drive on a 500 V AC line at 50 Hz. Too little drop and harmonics aren't suppressed; too much and the drive sees a sag under load. This one hits the sweet spot for most PWM drives in industrial panels. Footprint: 0.219 m wide × 0.179 m tall × 0.143 m deep. IP00 means it's an open-frame component — no enclosure, no touch protection. Mount it inside a ventilated cabinet with clearance for the 73 W coil loss plus 23 W iron-core loss to dissipate. If your enclosure ambient pushes past 40 °C, derate the continuous current or add forced air. The lifecycle stage is recorded as mature — Siemens has not flagged this order code for discontinuation. It remains a current catalogue item, though like most line reactors it is manufactured in batches rather than held on the shelf. We source it to order through our independent supply network; an RFQ returns current pricing and confirmed lead time. The part carries UL/CSA recognition per the EN 61558-2-20 standard cited in the product description. That means it meets North American safety isolation requirements for a drive input choke — no separate UL listing hunt needed for a panel destined for a US or Canadian line.","metaTitle":"Siemens 4EP4001-0US00 Mains Choke for Drive, 31.95 A, 500 V","metaDescription":"Siemens 4EP4001-0US00 mains choke for variable-frequency drives. 3-phase, 500 V AC, 31.95 A rated, 35.5 A max, 50 Hz, 4% voltage drop.
