That thermal curve is the one to check if this breaker sits near transformers or drives that push internal panel ambient above 50 °C. Mechanical endurance is listed at 15,000 operations — that's a solid number for a panel main or feeder breaker that cycles a few times a year, not a daily-switched disconnect. Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — that's a standard 3-pole MCCB envelope that drops into most DIN-rail or panel-mount SENTRON bases without re-drilling. This is a current-production part — no last-time-buy window, no scavenging required.","metaTitle":"Siemens 3VA1132-3EF32-0AH0 SENTRON MCCB, 32 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1132-3EF32-0AH0 molded case circuit breaker, 32 A rated, TM240 thermal-magnetic trip, 75.6 kA at 240 V.

The 3VA1132-3EF32-0AH0 carries a higher 32 A rating and a TM240 trip versus the 3VA1010's lower rating, so it's a functional upgrade — but check your selectivity coordination and wire sizing before swapping, since the higher continuous rating changes the upstream protection requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1132-3EF32-0AH0","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/3VA1132-3EF32-0AH0 when reusing this data.
