It is designed for starter protection — meaning it integrates overload and short-circuit protection for motor branch circuits in a single frame, with an undervoltage release (UVR) built in. The 200 A rating holds flat from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C, which is the maximum operating ambient temperature. The interrupting rating drops steeply as system voltage rises: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. For a 480 V panel, the 75.6 kA figure still provides substantial fault-current headroom for most industrial service-entrance or feeder applications. At 690 V the 4.5 kA limit means this breaker is not suitable for high-fault 690 V motor circuits without upstream current-limiting fuses or a higher-rated frame. The 3VA1220-6MH32-0DD0 occupies 70 mm depth, 105 mm width, and 158 mm height — a standard 3-pole MCCB footprint for DIN-rail or panel-mount installation. The undervoltage release (UVR) is factory-integrated; no separate module occupies adjacent DIN space. The three auxiliary switches (HQ design) provide status feedback for the open/closed and tripped states. If the breaker is mounted in a sealed enclosure above 50 °C, the 200 A rating must be derated per the published curve — at 60 °C it is 188 A, at 70 °C it is 176 A.","metaTitle":"Siemens 3VA1220-6MH32-0DD0 SENTRON MCCB, 200 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0DD0 molded case circuit breaker, 200 A rated, 3-pole, breaking capacity 220 kA at 240 V AC.
