The thermal rating holds 32 A flat from 40 °C to 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. For a panel running at 55 °C ambient, you lose 1 A of headroom. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint. It fits a 3-pole slot in a SENTRON distribution panel or any 76.2 mm-wide DIN-rail mount.","metaTitle":"Siemens SENTRON 3VA1032-4ED32-0KA0 MCCB, 32A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1032-4ED32-0KA0 molded case circuit breaker, 32A rated, 3-pole, 121kA interrupting at 240V.
