Thermal derating is mild: the breaker holds 50 A all the way to 50 °C, then drops to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That means in a hot panel near the top of the ambient range you lose only 5 A — not enough to force a resizing for most circuits, but worth checking if you're running at the margin. The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that drops into a SENTRON panel or any DIN-rail-mounting distribution board. If you need those extras, you're looking at a different variant in the 3VA family. ## Environmental range","metaTitle":"Siemens 3VA1050-3ED36-0AC0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1050-3ED36-0AC0 molded case circuit breaker, 50 A at 40 °C, 3-pole, TM210 release, 75.6 kA at 240 V.
