It carries a 220 kA interrupting capacity at 240 V — that rating drops to 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V, so the available fault current at the panelboard determines which voltage column governs your SCCR calculation. Continuous current holds at 200 A from 40 °C through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Maximum power loss is 42 W at rated current — that heat stays inside the panel, so factor it into the enclosure thermal budget alongside the other gear in the same compartment. ## Auxiliary switching and trip indication The trip alarm switch changes state only on a fault trip, not on manual open — useful for remote fault annunciation or a shunt-trip interlock. ## Environmental and insulation ratings The 70 mm depth, 105 mm width, and 158 mm height match the standard SENTRON 3VA mounting footprint — it bolts into the same panel cutout as other 3VA frame-size breakers.","metaTitle":"Siemens 3VA1220-6EF32-0AH0 SENTRON MCCB, 200A 3-Pole, 220kA","metaDescription":"Siemens SENTRON 3VA1220-6EF32-0AH0 molded case circuit breaker, 200A continuous at 40°C, 3-pole, 220kA interrupting at 240V.
