That is unusual for a compact MCCB and simplifies panel thermal budgeting. The 4 W maximum power loss is low enough that natural convection in a standard IP54 enclosure handles it — no forced cooling needed. ## Ground-fault and protection design That means it sums the phase currents internally and trips on residual imbalance — no external GFCI module required. It is a line-protection design (not motor or generator protection), so the trip curve is shaped for cable and busbar thermal limits. If you need remote status or undervoltage lockout, this is not the variant — the 3VA2 family carries those options in other order codes. But for a straight line protection breaker with integrated ground-fault, this is the one. No PCN or EOL notice on record.","metaTitle":"Siemens 3VA2163-7HM32-0AA0 SENTRON MCCB, 63 A, 3-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2163-7HM32-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, 330 kA breaking capacity at 240 V.

The difference is in the internal trip unit variant — the -8HM32 uses a different electronic trip curve. It drops into the same panel footprint and busbar layout without rewiring, but verify the trip characteristic matches your coordination study before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2163-7HM32-0AA0","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/3VA2163-7HM32-0AA0 when reusing this data.
