MCCB with full-rate 200 A at elevated ambient
The Siemens 3VA2220-0MS32-0AA0 is a SENTRON 3VA2 molded case circuit breaker rated for 200 A continuous current, and it holds that rating all the way from 40 °C up to 70 °C — no derating curve to chase in a hot panel. It carries a 3-pole construction with an electronic overcurrent release (ETU310M) that is adjustable from 300 A to 2400 A, so you can tune the pickup to protect a specific motor or feeder without swapping the breaker frame.
Front face is IP40 rated, suitable for general-purpose industrial panels where no washdown or dust ingress is expected.
