The 220 kA at 240 V is the headline number, but the 154 kA at 415 V is the one that matters for most European or 400 V-class panels; at 690 V it drops to 7.5 kA, which still covers most motor-starting duty but not a high-fault industrial bus. The auxiliary switch configuration (2 form-C contacts plus a dedicated alarm contact) covers most panel-wiring schemes without extra terminal blocks. Width is 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in) — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and DIN-rail mounting plates. The 70 mm depth means it clears shallow enclosures where a deeper breaker would hit the gland plate or back wall.","metaTitle":"Siemens 3VA1112-6MH32-0KH0 SENTRON MCCB, 125A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1112-6MH32-0KH0 molded case circuit breaker, 125A rated at 40°C, 220kA breaking at 240V. 3-pole, starter protection design.
