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.","metaTitle":"Siemens 3VA1050-3ED32-0HH0 SENTRON MCCB, 50A, 75.6kA at 240V","metaDescription":"Siemens 3VA1050-3ED32-0HH0 SENTRON molded case circuit breaker, 3-pole, 50A rated at 40°C, 75.6kA interrupting at 240V.

No rewiring of the panel layout is needed, but verify the load current and interrupting requirements match the 50 A rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1050-3ED32-0HH0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1050-3ED32-0HH0 when reusing this data.
