The thermal curve holds full 50 A up to 50 °C ambient; above that it derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Dimensions are 70 mm deep, 101.6 mm wide, 130 mm high — a standard SENTRON 4-pole MCCB footprint that mounts directly onto a DIN rail or panel-mount base. Front-side IP40 protection means it is suitable for enclosed panels where no water ingress is expected; keep it behind a gland plate or cabinet door.","metaTitle":"Siemens SENTRON 3VM1050-4ED42-0AA0 4-Pole MCCB, 50 A, 121 kA","metaDescription":"Siemens SENTRON 3VM1050-4ED42-0AA0 molded case circuit breaker, 4-pole, 50 A rated, TM210 release, 121 kA breaking at 240 V.
