It serves as a manual isolation point in a distribution panel. The front-terminal busbar connection keeps wiring clean in a panel — the 76.2 mm width (3-inch footprint) matches the standard 3VA1 frame spacing, so it aligns with adjacent breakers on the same busbar system. Rated continuous current Iu of 63 A sets the maximum load it can carry continuously without exceeding temperature limits. Short-time withstand ratings of 2 kA for both 0.5 s and 1 s (Limited To 0.5 S / Limited To 1 S) define how much fault current the disconnector can pass without welding or damage during the time it takes an upstream breaker to clear a fault. This is critical for selectivity coordination: if the upstream protective device clears in under 0.5 s at 2 kA, this switch disconnector stays intact and can be reclosed after the fault is cleared. Mechanical endurance of 15,000 operating cycles (latching endurance) tells you the expected life under normal switching — adequate for infrequent isolation but not rated for daily switching duty like a contactor. The front-terminal busbar connection accepts busbar fingers or cable lugs on the line and load sides — no box terminals, so plan for busbar tap-offs rather than individual ring terminals. The two auxiliary switches (2 CO) are wired via the front terminals; they share the same compact housing, saving space over a separate auxiliary contact block. The optional motor drive (product extension optional) means you can add remote motor operation later without replacing the disconnector — check the 3VA accessory catalog for the drive part number.","metaTitle":"Siemens 3VA1163-1AA32-0AC0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0AC0 switch disconnector, 63 A rated continuous current, 3-pole, 690 V AC / 500 V DC, IP40 front.

It will not drop in as a direct replacement because the 3VA1163-1AA32-0AC0 has no overcurrent protection — the 3VA1110-5ED36-0AC0 adds that function, so the panel design intent changes. Use the 3VA1110-5ED36-0AC0 only if you need both isolation and overload/short-circuit protection in one device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-1AA32-0AC0","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/3VA1163-1AA32-0AC0 when reusing this data.
