Rated continuous current holds at 125 A from 40 °C through 50 °C ambient, then steps down: 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. If the panel ambient hits 55 °C, plan for 120 A max continuous load — the 125 A label applies only below 50 °C. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep, with IP40 protection on the front face. ## Auxiliary release and trip options Two HQ auxiliary switches are integrated for status feedback (open/closed indication). No undervoltage release, no phase-failure detection, and no communication function are fitted; the TM210 overcurrent release handles only thermal-magnetic protection. The trip indicator is absent — visual trip flag is not provided on this variant.","metaTitle":"SIEMENS 3VA1112-5ED32-0KC0 SENTRON MCCB, 125 A, 187 kA @ 240","metaDescription":"SIEMENS SENTRON 3VA1112-5ED32-0KC0 molded case circuit breaker, 125 A rated continuous current, 187 kA breaking capacity at 240 V.
