That thermal curve matters when you're packing this into a panel with other heat sources: at 70 °C ambient you lose 5 A off the nameplate, so the load calculation for the branch circuit needs to account for the actual enclosure temperature, not the 40 °C reference point. ## Breaking capacity — what it can interrupt at your system voltage Short-circuit breaking capacity varies sharply with system voltage: 53 kA at 240 V AC, 32 kA at 415 V AC, 14 kA at 440 V AC, and 8 kA at 500 V AC. Dimensions are 76.2 mm wide (3 inches), 130 mm tall (5.12 inches), and 70 mm deep (2.76 inches) — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. Lifecycle status is current production.","metaTitle":"Siemens 3VM1050-2ED32-0AA0 SENTRON MCCB, 3-Pole, 50 A, TM210","metaDescription":"Siemens 3VM1050-2ED32-0AA0 SENTRON molded case circuit breaker. 3-pole, 50 A rated at 40 °C, TM210 thermal-magnetic trip.
