The thermal class B (130 °C insulation) and 40 °C ambient rating mean this choke can live in a closed panel without forced cooling as long as the surrounding air stays under 40 °C — above that, derate the current or add ventilation. This choke is an open-frame (IP00) device — no enclosure, no touch protection. The 0.143 m depth, 0.219 m width, and 0.179 m height footprint fits standard backplate layouts; plan for clearance around the terminals and airflow paths. Because it is IP00, the panel itself must provide the environmental seal and keep live parts inaccessible.","metaTitle":"Siemens 4EP4010-0LS20 mains choke, 80 A, 3-phase, 0.26 mH","metaDescription":"Siemens 4EP4010-0LS20 mains choke (Netzdrossel), 500 V AC, 80 A max, 0.26 mH, 3-phase, IP00, screw terminals.
