At 440 V it still clears 30 kA, and at 690 V it holds 17 kA — so it's usable on 480/277 V and 600 V industrial systems, though the lower 690 V rating means you check the available fault current at that voltage. Rated continuous current is 200 A from 40 °C through 50 °C ambient; it derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. ## Starter protection and auxiliary configuration This is the starter protection version (product version field), meaning the TM120M release is coordinated for motor starting inrush — it won't nuisance-trip on the locked-rotor current of a typical induction motor. That 105 mm width is a standard 4-module footprint for SENTRON 3VA MCCBs — it fits the same panel cutout and bus-bar spacing as other 3VA 3-pole frames.","metaTitle":"Siemens 3VA1220-5MH32-0CH0 SENTRON MCCB, 200 A, 3-Pole, Star","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0CH0 molded case circuit breaker, 200 A rated continuous current, 3-pole, starter protection. 187 kA at 240 V.
