For a 415 V industrial panel fed from a transformer with a 100 kA prospective fault current, this breaker clears it. At 690 V the margin is tighter — 17 kA limits it to lower-fault installations. ## Thermal derating — continuous current across ambient temperature Above that it derates: 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. Plan the load at the actual ambient, not the nameplate. The trip indicator flag is present — visible through the front cover, useful for troubleshooting without opening the panel door.","metaTitle":"Siemens 3VA1112-5EF32-0AG0 SENTRON MCCB, 125 A, 3-Pole, Line","metaDescription":"Siemens 3VA1112-5EF32-0AG0 SENTRON molded case circuit breaker, 125 A rated, 3-pole, TM240 release.
