The 75 W operating power at AC-3 duty at 400 V confirms it's sized for motor loads in that power class. The 220 kA at 240 V is the headline number, but the real-world rating for most industrial 400 V panels is 154 kA at 415 V. That's still very high — well above what a typical 100 kA SCCR panel needs. Compared to a smaller-frame SENTRON like the 3VA1010-2ED32-0JA0 (which tops out at lower current and breaking capacity), this 3VA1220 frame handles the 200 A continuous rating and the 220 kA interrupt rating — it's a physically larger unit at 105 mm wide, 158 mm tall, and 70 mm deep. The 3VA1010 won't drop into the same panel cutout without checking the mounting footprint. ## Panel integration — dimensions and mounting The continuous current rating holds at 200 A up to 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C.","metaTitle":"Siemens 3VA1220-6MH32-0AE0 SENTRON MCCB, 200 A, 220 kA","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0AE0 molded case circuit breaker, 200 A rated, 220 kA breaking at 240 V.

It measures 105 mm wide, 158 mm tall, and 70 mm deep, while the 3VA1010 frame is physically smaller. The mounting footprint and cutout dimensions differ; you'd need to verify the panel layout before swapping."},{"question":"What does the TM120M release mean on this MCCB?","answer":"TM120M is a thermal-magnetic overcurrent release. The thermal element handles overload protection (slow response to sustained overcurrent), and the magnetic element handles short-circuit protection (instantaneous trip on high fault current). The '120' refers to the release rating in amps, and 'M' indicates it's a magnetic-only or thermal-magnetic type suitable for motor starting."},{"question":"What auxiliary contacts come with 3VA1220-6MH32-0AE0?","answer":"It comes with 4 HQ auxiliary switches built in. These are high-quality (HQ) form-C contacts for status feedback — typically used to signal the breaker's open/closed/tripped state to a PLC or indicator panel. No undervoltage release or shunt trip is included."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1220-6MH32-0AE0","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/3VA1220-6MH32-0AE0 when reusing this data.
