The TM210 thermal-magnetic release handles overloads and short-circuits in one compact package, no auxiliary power needed. Rated 50 A at 40 °C, but the current you can carry drops as the panel warms: 49 A at 45 °C, 47 A at 50 °C, 46 A at 55 °C, 44 A at 60 °C, 43 A at 65 °C, and 41 A at 70 °C. The maximum power loss is 9.7 W, which drives the internal temperature rise inside the enclosure. Width 76.2 mm, height 129.4 mm, depth 75.1 mm — a standard 3-pole MCCB footprint for DIN-rail or panel-mount.","metaTitle":"Siemens 3VA4150-5ED34-0AA0 SENTRON MCCB, 50A, 85kA at 240V","metaDescription":"Siemens 3VA4150-5ED34-0AA0 SENTRON molded-case circuit breaker, 3-pole, 50 A at 40 °C, 85 kA at 240 V, TM210 release.
