That puts it in the high-interrupting class for a 50 A frame — it clears a bolted fault upstream without the arc chute failing, which matters when the transformer is right around the corner from the panel. Thermal derating is published across the full operating range: full 50 A up to 50 °C, then 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Footprint is 130 mm high × 50.8 mm wide × 70 mm deep — a standard 2-pole MCCB width for DIN-rail or screw-mount panels.","metaTitle":"Siemens 3VA1150-4ED26-0AA0 SENTRON MCCB, 50A, 121kA at 240V","metaDescription":"Siemens 3VA1150-4ED26-0AA0 SENTRON molded case circuit breaker, 2-pole, 50A rated, TM210 release, 121kA at 240V AC.
