It is rated 50 A continuously at 40 °C ambient, with a thermal derating curve that holds flat to 50 °C (still 50 A) and then steps down: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The breaking capacity is substantial: 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. For a 50 A frame, that is serious fault-current headroom; it will clear a high-energy fault on a 240 V secondary without upstream coordination worries.
The 3VM1150-3ED32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.
Trip Unit and Protection Design
The TM210 designation indicates a thermal-magnetic trip with a fixed time-current characteristic — thermal for overloads, magnetic for short-circuits. This is a line-protection design, meaning it is optimized for feeder and distribution circuits rather than motor-starting duty. If you need ground-fault or communication, you would step up to a 3VA-series breaker with electronic trip.
