The interrupting ratings are 187 kA at 240 V, 121 kA at 415 V, 30 kA at 440 V, and 17 kA at 690 V — these are the maximum fault currents the breaker can safely clear at those voltages, so for a 415 V supply you need the available fault current at the panel to be at or below 121 kA. ## Panel integration and physical fit Dimensions are 105 mm wide, 158 mm high, and 70 mm deep — the 105 mm width is the standard 3-pole MCCB footprint for this SENTRON frame, so it fits existing panel cutouts and busbar spacing designed for the 3VA family. ## Auxiliary and trip options The integrated auxiliary trip order code is 3VA9688-0BL32 — a factory-fitted accessory that should match the BOM if a replacement is needed. No undervoltage release, no communication function, no phase failure detection, and no ground fault monitoring are included — this is a straightforward thermal-magnetic breaker without electronic trip unit or network connectivity.","metaTitle":"Siemens 3VA1220-5MH32-0JH0 SENTRON MCCB, 200 A, 3-Pole, Star","metaDescription":"Siemens 3VA1220-5MH32-0JH0 SENTRON molded case circuit breaker, 200 A rated, 3-pole, TM120M release, 187 kA at 240 V.
