The interrupting ratings are what separate this from a standard MCB. At 240 V it clears 220 kA — that's a very high fault-current capability, sized for the main breaker position close to a large transformer. At 415 V it's still 154 kA, at 440 V it's 75.6 kA, at 500 V it drops to 30 kA, and at 690 V it's 17 kA. If your system voltage lands between those test points, the lower adjacent rating governs; don't interpolate upward. The 140 mm width for a 4-pole MCCB is standard — it occupies roughly 5.5 inches of DIN-rail or mounting-plate space. If you're swapping this into an existing panel, measure the available width first; a 3-pole unit won't fit the same footprint. Maximum power loss is 42 W at rated load.","metaTitle":"Siemens 3VA1220-6FF42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6FF42-0AA0 molded case circuit breaker, 100 A frame, 4-pole, TM240 trip, 220 kA at 240 V.
