Breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. For a 415 V three-phase distribution board, that 154 kA gives you serious fault-current headroom — enough to coordinate downstream without cascading failures on a high-capacity transformer. This is a 3-pole unit designed for starter protection — meaning it's built to handle motor-starting inrush and coordinate with a contactor/overload pair, not just general branch-circuit protection. ## Integrated auxiliaries and releases That means you get remote tripping capability and status feedback without buying add-on modules — one less sourcing line item. The basic switch inside is the 3VA12206MH320AA0, which is the core switching mechanism. If you need UVR or ground-fault, this isn't the order code; look at the 3VA1 family with the appropriate suffix. ## Panel fit and environmental range That -25 °C low end is fine for unheated pump houses or outdoor enclosures in most climates.","metaTitle":"Siemens 3VA1220-6MH32-0JH0 SENTRON MCCB, 200 A, 154 kA at 41","metaDescription":"Siemens 3VA1220-6MH32-0JH0 SENTRON molded case circuit breaker, 200 A, 3-pole, 154 kA breaking capacity at 415 V.
