It breaks 75.6 kA at 240 V AC, 52.5 kA at 415 V, and still holds 11.9 kA at 690 V — that SCCR headroom keeps selectivity downstream without forcing a bigger frame upstream. The TM240 release is fixed, non-interchangeable — no spare trip unit to swap if the load changes. That keeps the BOM simple for a fixed line-protection role, but if you need field-adjustable thermal or magnetic settings, look at the 3VA1 with electronic releases. The 75.6 kA at 240 V is the highest interrupting rating on this breaker; at 415 V it drops to 52.5 kA, and at 690 V it's 11.9 kA. That 52.5 kA at 415 V is enough for most 400 V distribution panels with a transformer upstream — you get full selectivity with a 100 A frame against a 630 A main without cascading. ## Panel integration — dimensions and fit The 3VA1110-3EF32-0AG0 measures 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON distribution panel or a generic DIN-rail enclosure without re-drilling. At 25 W max power loss, it's within the thermal budget of a ventilated IP54 enclosure; derate the 100 A rating above 55 °C per the thermal curve (98 A at 55 °C, 91 A at 70 °C).","metaTitle":"Siemens 3VA1110-3EF32-0AG0 SENTRON MCCB, 100A, 3-Pole, 75.6k","metaDescription":"Siemens SENTRON 3VA1110-3EF32-0AG0 molded case circuit breaker, 100A rated at 40°C, 3-pole, 75.6kA breaking at 240V.
