The screw-type terminals on the main circuit accept lugs or ring terminals; plan for panel space measuring 0.219 m wide by 0.179 m tall by 0.123 m deep. Thermal class B (130 °C) insulation per IEC 60085 means the winding can sustain continuous operation at 40 °C ambient without exceeding its rated temperature rise.","metaTitle":"Siemens 4EP3910-7AS20 Mains Choke, 50A 3-Phase 500V","metaDescription":"Siemens 4EP3910-7AS20 Netzdrossel mains choke, 50A max, 45A rated, 0.42mH, 500V AC, 3-phase, IP00.
