That kind of interrupting ability at the lower voltages tells you it's meant for high-fault panels where an ordinary MCCB would weld shut. That's the difference between a breaker that trips blind and one that lets you hold selectivity. The 3VA2 frame size (105 mm wide, 181 mm tall, 86 mm deep) fits standard panel-mount cutouts; the IP40 front means it's splash-protected on the face, but don't hose it down — this is a dry-gear breaker. ## Thermal derating — what the 100 A means at panel ambient At 55 °C it's 96.25 A, at 60 °C it's 92.5 A, at 65 °C it's 88.75 A, and at 70 °C it's 85 A. That's a wide thermal window; it'll survive a cold warehouse and a hot enclosure. ## Auxiliary contacts and trip unit The ETU350 trip unit handles the overcurrent protection; the breaker itself has no voltage trigger, no phase-failure detection, and no communication function. It's a straightforward line-protection MCCB — you wire the load, set the trip thresholds, and it sits there interrupting faults until the end of its 20,000-cycle mechanical life.","metaTitle":"Siemens 3VA2010-5HN32-0AD0 SENTRON MCCB, 100 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2010-5HN32-0AD0 molded case circuit breaker, 100 A rated continuous current, 3-pole, ETU350 trip unit, breaking capacity up to 187 kA at 240 V.

The 3VA2010-5HN32-0AD0 carries a higher breaking capacity (187 kA vs lower-rated siblings) and uses an ETU350 electronic trip unit versus the 3VA1010's thermal-magnetic. If the panel's SCCR and trip coordination were designed for the 3VA1010, this breaker will physically fit but you must verify the trip curve and interrupting rating match the system design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2010-5HN32-0AD0","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/3VA2010-5HN32-0AD0 when reusing this data.
