It is a pure disconnecting means: no trip unit, no undervoltage release, no auxiliary contacts. That makes it the right choice when you need a visible-break isolator that fits a standard MCCB footprint and handles full rated current across the entire operating temperature range. That simplifies panel thermal budgeting in warm enclosures or near other heat sources. Insulation voltage is rated 800 V; operating voltage is 690 V AC or 600 V DC, so it covers 480 V and 600 V class systems with headroom. Mechanical service life is 15,000 operating cycles typical. That is adequate for routine isolation in a panel that sees weekly or monthly switching. ## Mounting and Connection Main circuit connection is busbar-compatible via front terminals — the busbar connection type and front terminal arrangement mean it integrates into standard panel busbar systems without adapters. That width is a standard 4-pole MCCB footprint; verify busbar pitch matches your existing layout. No auxiliary switch or release fitted, and no communication function. Optional motor drive can be added via the product extension slot if remote operation is needed. For compliance documentation: as a Siemens SENTRON product, it carries the usual CE marking for the European market and is designed to relevant IEC standards (IEC 60947-3 for switch-disconnectors). RoHS and REACH declarations are available from Siemens documentation portal using the order code.","metaTitle":"Siemens 3VA1163-1AA42-0AA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0AA0 switch disconnector in MCCB design. 63 A continuous at 40-70 °C, 4-pole, IP40 front, active production.

They share the same frame size and busbar connection pattern, so panel cutout and busbar pitch are compatible, but the wiring and protection scheme are different. Do not substitute without reviewing the protection requirements of your circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-1AA42-0AA0","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/3VA1163-1AA42-0AA0 when reusing this data.
