At 240 V it interrupts 121 kA — that's the headline SCCR figure for this frame. At 415 V and 440 V it still holds 76 kA; at 500 V it drops to 53 kA. The SCCR at each voltage level determines whether this breaker alone satisfies the fault rating for the whole panel or you need upstream coordination. Above 50 °C it steps down: 313 A at 55 °C, 306 A at 60 °C, down to 292 A at 70 °C. The 3VM1332-4ED42-0AA0 measures 248 mm high, 184 mm wide, and 110 mm deep — a 4-pole frame that fits standard distribution panel cutouts. In a sealed panel with multiple breakers, factor that into your thermal budget or you'll hit the derating curve sooner than the ambient temperature alone suggests.","metaTitle":"SENTRON 3VM1332-4ED42-0AA0 MCCB, 320 A, 121 kA at 240 V","metaDescription":"SENTRON 3VM1332-4ED42-0AA0 molded case circuit breaker, 4-pole, 320 A at 40 °C, 121 kA at 240 V, TM210 release.

Panel cutout dimensions and mounting pattern differ between the two series — verify the footprint against your existing backplate before ordering. The 3VM1332 is a 4-pole 320 A frame; the 3VA1010 is a smaller 3-pole 100 A frame, so they are not direct mechanical swaps."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VM1332-4ED42-0AA0","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/3VM1332-4ED42-0AA0 when reusing this data.
