It's designed for 500 V AC line voltage at 50/60 Hz and carries a 2.7% relative inductive voltage drop at rated conditions. The 106 A maximum / 95 A rated current tells you this choke is sized for a 95 A continuous motor or drive load, with headroom to 106 A for short-duration overloads. The 0.24 mH inductance at 500 V AC gives a typical line-reactor impedance that limits harmonic distortion and inrush current on variable-frequency drives or soft starters in that current class. IP00 means it's an open-frame component — no enclosure protection. The free cable endings (main circuit connection) require a terminal block or lug connection at the panel builder's end. Power dissipation breaks down as 50 W in the coil and 31 W in the iron core, totaling 81 W at rated load. ## Integration notes Mounting dimensions: 0.219 m wide × 0.179 m tall × 0.143 m deep. The open-frame construction (IP00) means it's panel-mounted, typically bolted to a mounting plate inside the enclosure. Free cable endings for the main circuit require field wiring to a terminal block or busbar. Thermal class B per IEC 60085 means the insulation system is rated for 130 °C maximum hot-spot temperature. Ambient temperature rating is 40 °C — derate current if ambient exceeds that.","metaTitle":"Siemens 4EP4010-0NS10 Mains Choke, 106A, 0.24 mH, 500 V AC","metaDescription":"Siemens 4EP4010-0NS10 mains choke (Netzdrossel). 106 A max, 95 A rated, 0.24 mH, 500 V AC, 50/60 Hz.
