SENTRON 3VA1220-6EF32-0AB0 — 200 A MCCB with TM240 Release
The interrupting ratings span the common industrial voltages: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Power loss at rated load is 42 W maximum — relevant for enclosure thermal calculations when grouping multiple breakers.
The 200 A rating holds from 40 °C through 50 °C, then derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The 70 mm depth leaves clearance for rear-connected busbars in a typical 200 mm deep enclosure. Comes with two HP auxiliary switches factory-fitted.
