The 200 A rating holds flat from 40 °C to 50 °C ambient, then derates to 176 A at 70 °C — so in a hot panel near a drive or transformer, you lose 24 A off the top. Plan your load margin accordingly. Rated insulation voltage Ui is 800 V, meaning the internal creepage and clearance are designed for 690 V line-to-line systems (the 690 V breaking is 11.9 kA). That's a common spec for 600 V class industrial distribution in North America. It ships with a factory-fitted shunt trip (order code 3VA9688-0BL30 for the release assembly) and two HQ auxiliary contacts. Mounts in a standard panel cutout or on a DIN-rail adapter. The 70 mm depth keeps it clear of shallow backpanels. Wire range for the line and load terminals is not listed here, but the 200 A rating typically requires 2/0 AWG to 4/0 AWG copper — confirm lug kit compatibility with the panel schedule. The shunt trip coil fires on a separate control voltage; verify polarity and voltage rating from the release order code documentation before wiring into a 24 VDC safety circuit.","metaTitle":"Siemens 3VA1220-4EF32-0HC0 SENTRON MCCB, 200 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0HC0 molded case circuit breaker, 200 A continuous, 3-pole, 121 kA breaking at 240 V.
