The 3-pole frame carries a 220 kA breaking capacity at 240 V, stepping down to 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so it's sized for high-fault industrial panels where the available short-circuit current is substantial. This is the MCCB you'd find on the line side of a motor starter combination, not a feeder breaker in a lighting panel. The shunt trip is listed as 3VA9688-0BL30, so if you're replacing one in a panel, that's the release module to verify against your existing wiring. ## Thermal derating and ambient conditions Above that, it derates: 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. Dimensions: 105 mm wide, 158 mm high, 70 mm deep. The 105 mm width is the 3-pole frame footprint; if you're swapping into an existing panel that was laid out for a 3VA1110 frame (100 A class), check the bus-bar spacing and mounting hole pattern — the 200 A frame is physically larger and may not drop in without drilling new holes or replacing the bus stack. Operating power at AC-3 duty (motor switching) at 400 V is 75 W — that's the switching load, not the motor power. The TM120M release is a fixed thermal-magnetic type; no electronic adjustment or communication. Latching endurance is 15,000 operations — adequate for a main disconnecting means or infrequent motor switching, not for a frequent-start application.","metaTitle":"Siemens 3VA1220-6MH32-0HC0 SENTRON MCCB, 200 A, 220 kA","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0HC0 molded case circuit breaker, 200 A rated, 220 kA at 240 V.
