That 121 kA figure at 240 V is the one that matters for North American 240/120 V split-phase or 240 V delta services — it gives plenty of headroom above typical available fault currents, so selectivity with downstream breakers is easier to achieve. The 200 A rating holds from 40 °C through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. That 105 mm width is three 35 mm DIN-module slots if you are thinking about rail space in a packed enclosure — it will occupy three full positions on the DIN rail. The 70 mm depth keeps it from projecting far past the backpanel, which helps when the enclosure has a shallow gland plate or a rear-mounted busbar system.","metaTitle":"Siemens 3VA1220-4EE32-0AA0 SENTRON MCCB, 200 A, 3-Pole, TM22","metaDescription":"Siemens SENTRON 3VA1220-4EE32-0AA0 molded case circuit breaker, 200 A at 40 °C, 3-pole, TM220 thermal-magnetic trip, 121 kA at 240 V.
