That thermal curve matters in a warm panel — if the enclosure ambient sits at 55 °C, you're limited to 120 A continuous, not the full 125 A. The TM240 thermal-magnetic release handles the overload and short-circuit trip curve. Breaking capacity runs 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The 690 V rating at 17 kA still covers most industrial 600 V class systems. Front protection is IP40 — fine for a closed panel, not for washdown exposure. ## Integrated accessories and wiring The auxiliary contact version is already built in — no separate order needed for basic status feedback. The integrated auxiliary trip uses order code 3VA9688-0BL33 if you need a replacement module. If you need remote monitoring or ground fault, you'd step up to a different 3VA variant with those modules. The 70 mm depth fits most distribution panels.","metaTitle":"Siemens 3VA1112-6EF32-0KH0 SENTRON MCCB, 125 A, 220 kA at 24","metaDescription":"Siemens 3VA1112-6EF32-0KH0 SENTRON molded case circuit breaker, 125 A rated current, 220 kA breaking at 240 V.
