Its interrupting capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V — figures that define its fault-clearing capability at the point of installation. The TM220 release combines a thermal element for overload protection and a magnetic element for short-circuit protection, tuned to the 50 A frame. Continuous current holds at 50 A from 40 °C through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — the thermal curve governs panel loading when ambient exceeds 50 °C. Maximum power loss is 14.6 W; account for this in enclosure thermal calculations, especially in sealed cabinets with multiple breakers. Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — the 4-pole width is wider than a 3-pole equivalent, so verify the DIN-rail or mounting-plate allocation before panel layout.","metaTitle":"Siemens 3VA1150-3EE46-0AA0 SENTRON MCCB, 50 A, 4-Pole, TM220","metaDescription":"Siemens 3VA1150-3EE46-0AA0 SENTRON molded case circuit breaker, 50 A continuous at 40 °C, 4-pole, TM220 release, interrupting rating 75.6 kA at 240 V.
