Its breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — numbers that tell you it's sized for high-fault industrial distribution panels, not light commercial subfeeds. ## Thermal derating and the TM240 release The 100 A rating holds flat from 40 °C to 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. That's a gentle slope — you don't lose a full breaker size until you're past 65 °C inside the enclosure, which buys headroom for a tightly packed panel. The two auxiliary switches HQ are pre-wired to a terminal block; verify the NO/NC assignment against your PLC input card before powering up. No communication module or phase-failure detection on this order code, so if you need remote trip indication beyond the aux contacts, plan a separate monitoring relay.","metaTitle":"Siemens 3VA1110-3EF32-0AC0 SENTRON MCCB, 100 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1110-3EF32-0AC0 molded case circuit breaker, 100 A rated, 75.6 kA at 240 V.
