It carries a 106 A maximum current rating and a 95.4 A continuous rated current at 500 V AC, 50/60 Hz, with a 0.2 mH inductance and a 2.7 % relative inductive voltage drop at rated conditions. The 95.4 A rated current is the continuous thermal limit at 40 °C ambient with Class B insulation (130 °C hot-spot). The 106 A maximum figure is the overload ceiling — sustained operation above 95.4 A requires derating. The 2.7 % voltage drop at rated current tells you the choke's impedance: at 50 Hz, 0.2 mH gives roughly 0.063 Ω per phase, dropping about 6 V line-to-line at 95.4 A. That's a standard value for input line reactors in the 100 A class — enough to blunt drive-commutation notches without excessive voltage loss. Dimensions are 0.219 m wide × 0.179 m tall × 0.143 m deep — about the footprint of a small contactor stack. Mounting is via the chassis base; no DIN rail clip. Plan for free air around it; Class B insulation means the surface runs warm (up to 130 °C winding hot-spot), so leave clearance from heat-sensitive wiring or plastic duct.","metaTitle":"Siemens 4EP4010-0NS20 Mains Choke, 106A, 0.2mH, IP00","metaDescription":"Siemens 4EP4010-0NS20 mains choke (Netzdrossel). 106A max, 95.4A rated, 0.2mH, 500V AC, 50/60Hz.
