The total power loss breaks into 350 W in the coil and 236 W in the iron core, so roughly 586 W of heat to vent. With IP00, it's a bare choke — no enclosure, no finger-safe cover. Mount it inside a cabinet with enough ventilation or forced air to handle that dissipation, and use the flat connectors for the main circuit terminations. ## Physical footprint Dimensions: 0.35 m wide, 0.321 m tall, 0.227 m deep.","metaTitle":"Siemens 4EU3652-8UC00-0A Mains Choke, 225A, 400V, 50Hz","metaDescription":"Siemens 4EU3652-8UC00-0A mains choke (Netzdrossel), 225A max, 400V AC, 50Hz, 0.22mH, IP00, thermal class H.
