The thermal derating curve is flat from 40 °C to 50 °C (50 A), then steps down to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. ## Physical Integration and Panel Fit The 3-pole footprint is standard for 50 A frames; verify gland-plate clearance for the 70 mm depth, especially in shallow enclosures. The shunt trip occupies the auxiliary slot and requires a separate control voltage — confirm polarity and suppression per the wiring diagram. ## Power Loss and Operating Range Maximum power loss is 14.6 W at rated current — relevant for thermal budgeting inside sealed enclosures.","metaTitle":"Siemens 3VA1050-3ED36-0JA0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1050-3ED36-0JA0 SENTRON molded case circuit breaker, 50 A rated at 40 °C, 3-pole, 75.6 kA breaking capacity at 240 V.
