It is built on the IEC frame 160 platform and is intended strictly for isolation and switching duty: it provides no overload protection (no thermal trip) and no short-circuit protection (no magnetic trip). That makes it a straight disconnect for a load circuit where upstream protection is already in place. The main circuit connects via busbar connection at the front terminals — a clean, low-profile fit for panel builds where you want the bus run straight onto the device without extra adapters. The 3VA1112-1AA32-0AA0 measures 70 mm deep by 76.2 mm wide by 130 mm high. Front IP40 protection is suitable for clean indoor panels. Mechanical service life is 15 000 operating cycles typical. ## What it does not do — and why that matters This switch disconnector has no trip indicator, no undervoltage release, no auxiliary contacts, and no communication function. It is a bare disconnect — you add the accessories as optional extensions.","metaTitle":"Siemens 3VA1112-1AA32-0AA0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0AA0 switch disconnector, 125 A continuous at 40-70 °C, 3-pole, IEC frame 160.

The difference is functional: the -5EE32 variant includes overload and short-circuit protection; the -1AA32 is a bare disconnect. If the panel design relies on the protection elements in the -5EE32, swapping to the -1AA32 would leave the circuit unprotected. Verify the protection scheme before substituting."},{"question":"What is the depth of 3VA1112-1AA32-0AA0?","answer":"The depth is 70 mm, with a width of 76.2 mm and height of 130 mm."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-1AA32-0AA0","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/3VA1112-1AA32-0AA0 when reusing this data.
