What this 3VA1050-3ED32-0HH0 brings to the panel
The Siemens 3VA1050-3ED32-0HH0 is a SENTRON molded case circuit breaker — 3-pole, line-protection design, rated 50 A continuous at 40 °C with no derating up to 50 °C. Above that it steps down: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C (–). That thermal curve matters if the breaker sits near other heat sources in a crowded enclosure — the 70 °C figure is the operating maximum. Interrupting capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V (–). If you need remote trip via a PLC digital output the shunt trip is already there; if you need undervoltage protection you'll pick a different suffix.
Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth (–, –). Storage range -40 to 80 °C; operating ambient -25 to 70 °C. The trip indicator and voltage trigger are present. No communication function, so this is a standalone thermal-magnetic breaker — no Modbus, no PROFIBUS, no remote metering.
