It is a 3-pole, non-fused disconnect intended for isolation and switching duty, not for overload or short-circuit protection (no trip unit, no overload release). The built-in shunt trip (STL) release operates on 110–127 V DC or AC 50/60 Hz, allowing remote emergency-off or controlled disconnection from a PLC or safety relay output. Mechanical endurance is 15,000 operating cycles — typical for a switch disconnector in this frame size. Maximum power loss is 38 W, which matters for enclosure heat load calculations if multiple units are ganged. ## Deployment context Mounts on a DIN rail or panel via the 3VA1 frame footprint (130 mm height, 76.2 mm width, 70 mm depth) and connects via busbar or front terminals — common in Siemens SENTRON distribution boards and MCCB-style switchgear. The shunt trip release makes it a natural fit for safety circuits requiring remote disconnect, such as emergency-stop chains or controlled isolation in automated machinery.","metaTitle":"Siemens 3VA1163-1AA32-0JA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA32-0JA0 SENTRON switch disconnector, 63 A rated current flat to 70 °C, shunt trip (STL) 110–127 V DC/AC, 3-pole, IP40 front, active production.

However, the 3VA1010-2ED32-0JA0 is a molded case circuit breaker with overcurrent protection, while the 3VA1163-1AA32-0JA0 is a switch disconnector without overload or short-circuit protection, so the wiring and protection scheme must be reviewed; the busbar connection type also differs (lug terminal on the breaker vs. busbar connection on the disconnect)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-1AA32-0JA0","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/3VA1163-1AA32-0JA0 when reusing this data.
