The unit includes a factory-installed shunt trip (STL) and two HQ auxiliary switches, saving a panel-build step versus field-fitting them later. Rated 200 A continuous at 40 °C through 50 °C ambient; above that the breaker derates linearly to 176 A at 70 °C. Maximum power loss is 42 W per pole — enough heat to factor into enclosure ventilation if you are stacking multiple breakers in a sealed cabinet. The depth leaves clearance for rear-connected bus bars or a cable entry gland plate.","metaTitle":"Siemens 3VA1220-6MH32-0JC0 SENTRON MCCB, 200 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0JC0 molded case circuit breaker, 200 A rated, 3-pole, 220 kA at 240 V.
