At 40 °C this breaker carries a full 200 A. Derate linearly above that: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. If your panel ambient runs warm — say near a drive cabinet or in a non-conditioned enclosure — use the 55 °C or 60 °C column for sizing. The TM120M release is factory-set for motor or mixed loads; no voltage-trip or ground-fault module fitted as standard. The interrupting ratings tell you where this breaker fits in the fault-current hierarchy: 187 kA at 240 V (low-voltage distribution), 121 kA at 415 V (common industrial), 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. For a 480 V system you interpolate between the 440 V and 500 V numbers — still well above typical available fault current in most plants.","metaTitle":"Siemens 3VA1220-5MH32-0AB0 SENTRON MCCB, 200 A, 3-Pole","metaDescription":"Siemens 3VA1220-5MH32-0AB0 SENTRON molded case circuit breaker, 200 A, 3-pole, 121 kA at 415 V.
