The 50 A thermal rating holds flat from 40 °C through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That means a panel at 60 °C still carries 48 A continuous — enough for a 45 A motor feeder or a 50 A bus tap that sees ambient rise inside a sealed enclosure. ## Integration and auxiliary fit The shunt trip lets a remote safety relay or E-stop chain drop the breaker without pulling the handle. The 70 mm depth matters for shallow backpanels or gland-plate clearance — it fits the same cutout as other 3VA1 frames, so a panel built for a 3VA1110-5ED36-0AC0 accepts this unit without enclosure modifications. The 800 V insulation rating means it can sit on a 690 V bus with full margin to the 1 kV dielectric test.","metaTitle":"Siemens 3VA1150-3EF36-0JC0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1150-3EF36-0JC0 molded case circuit breaker, 50 A, 3-pole, 75.6 kA breaking capacity at 240 V.
