What this 3VA1050-2ED32-0DC0 brings to the panel
This is a Siemens SENTRON 3VA1050-2ED32-0DC0 molded case circuit breaker — 3-pole, 50 A continuous rating, built around the TM210 thermal-magnetic overcurrent release. It's a line-protection breaker, not a motor-protection or ground-fault device, so keep that straight when you're ordering for a feeder circuit. The breaking capacity tells you where it'll hold fault current: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. No communication module, no phase-failure detection — this is a straightforward breaker for basic feeder protection with undervoltage trip.
Temperature derating and fit
Above that it starts to taper: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C.
