The 200 A rating holds flat from 40 °C up to 50 °C, then derates linearly to 176 A at 70 °C, so if your panel ambient runs above 50 °C you need to account for the reduced ampacity. Breaking capacity is 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 — that's the maximum fault current the breaker can safely interrupt at each voltage level, which drives your SCCR coordination study. Dimensions are 105 mm wide, 158 mm high, and 70 mm deep — that's a 4.13 x 6.22 x 2.76 inch footprint. The TM120M trip unit is field-replaceable, and the breaker accepts plug-in accessories (shunt trip, auxiliary switches) without removing the main body from the panel. As a SENTRON-series MCCB from Siemens, this breaker carries UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications. The manufacturer provides RoHS and REACH compliance declarations, along with a CE declaration of conformity for the European market. The 3VA family also has a comprehensive IEC/UL coordination study available from Siemens — useful for the site electrical engineer's selectivity analysis.","metaTitle":"Siemens 3VA1220-6MH32-0AJ0 SENTRON MCCB, 200 A, 3-Pole, Star","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0AJ0 molded case circuit breaker, 200 A rated, 3-pole, TM120M trip, 220 kA at 240 V.
