The interrupting capacity tells you where it can sit in the distribution: 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. Derating is baked in: the breaker holds 200 A flat from 40 °C through 50 °C, then steps down to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If your panel ambient runs 55 °C, size the load at 194 A, not 200 A. The IP40 front protection means it's suitable for indoor panel mounting where tools or fingers won't contact live parts — no washdown rating here, so keep it behind the gland plate. ## Integration and auxiliary wiring The undervoltage release (UVR) is built in — designated as 3VA9608-0BB24 for the integrated auxiliary trip — so a loss of control voltage drops the breaker open, which is standard for emergency-stop or safety isolation circuits. Dimensions are 70 mm deep, 105 mm wide, 158 mm tall — standard SENTRON 3VA footprint for the 200 A frame. It mounts directly to a DIN rail or panel plate via the integrated latching mechanism, with 15 000 latching cycles endurance. The trip indicator (red/green flag) gives a quick visual on whether the breaker tripped on fault or was manually opened, which saves troubleshooting time on a crowded panel.","metaTitle":"Siemens 3VA1220-6EF32-0CH0 SENTRON MCCB, 200 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6EF32-0CH0 molded case circuit breaker, 200 A rated, 3-pole, 220 kA at 240 V.
