The interrupting capacity at 240 V is 220 kA, dropping to 154 kA at 415 V and 36 kA at 440 V; at 690 V it still holds 17 kA. That 220 kA figure at 240 V covers high-fault utility feeds and transformer secondaries where available fault current can exceed 100 kA — this breaker clears without cascading upstream. The 200 A rating holds flat from 40 °C to 50 °C ambient; above that it derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. In a sealed panel with a 55 °C internal ambient, the usable continuous current is 192 A — plan the load accordingly. Dimensions are 105 mm wide × 158 mm high × 70 mm deep; the 105 mm width is a standard 6-module footprint for SENTRON 3VA fixed-breaker mounting plates. ## Auxiliary contacts and shunt trip — what ships on the frame The STL allows remote tripping from an E-stop or safety PLC signal; the trip alarm switch closes on fault trip, giving a separate signal path from the aux contacts that follow the main contacts. The shunt trip order code for replacement or spares is 3VA9688-0BL30.","metaTitle":"Siemens 3VA1220-6MH32-0HH0 SENTRON MCCB, 200 A, 220 kA","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0HH0 molded case circuit breaker, 200 A rated, 220 kA at 240 V, 3-pole, starter protection, TM120M release.
