The optional motor drive (product extension) allows remote switching for automated disconnection sequences. Power loss is 38 W max at rated current. Mechanical endurance is 15,000 latching cycles.","metaTitle":"Siemens 3VA1163-1AA32-0KH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0KH0 switch disconnector, 63 A rated continuous current, 3-pole, shunt trip 220-250V DC / 208-277V AC, 2 aux switches + 1 trip alarm.

It will drop into the same panel cutout but does not serve as a direct functional replacement for a switch disconnector."},{"question":"Will 3VA1163-1AA32-0KH0 drop into a panel specified around 3VA1010-2ED32-0JC0 without rewiring?","answer":"Yes — both parts share the same 70 mm depth, 76.2 mm width, and 130 mm height, and both use front-terminal busbar connections, so the physical swap is direct. However, the 3VA1163-1AA32-0KH0 is a switch disconnector without overcurrent protection, so the upstream protection scheme must be reviewed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-1AA32-0KH0","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/3VA1163-1AA32-0KH0 when reusing this data.
