Front terminals accept busbar connection; the switch is designed for DIN-rail or direct-panel mounting in a standard MCCB footprint. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — the same width as a 3-pole 160 A frame breaker, so it drops into existing busbar layouts without re-spacing. IP40 on the front face suits enclosed distribution boards; no IP rating on the rear, so it needs a panel or enclosure backplane. Rated insulation voltage is 800 V, operating voltage 690 V AC / 500 V DC — this switch disconnector is suitable for 400 V and 690 V line-to-line systems. Mechanical service life is 15,000 operating cycles typical; no electrical life figure is listed, but as a no-fault-break switch it is intended for infrequent load-break or isolation duty, not daily motor starting.","metaTitle":"Siemens 3VA1163-1AA32-0CA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA32-0CA0 switch disconnector, 63 A rated current, 3-pole, undervoltage release 120-127 V AC.

The 3VA1163-1AA32-0CA0 has no overcurrent protection — it is a pure disconnect. They share the same frame size, mounting footprint, and terminal arrangement, so the 3VA1163-1AA32-0CA0 can physically replace the MCCB in a panel if overcurrent protection is provided upstream, but the functions are not equivalent."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-1AA32-0CA0","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/3VA1163-1AA32-0CA0 when reusing this data.
