The 800 V rated insulation voltage (Ui) and 690 V AC / 500 V DC operational voltage (Ue) cover standard 400/480 V and 690 V industrial distribution. The part is a pure disconnect — no overload or short-circuit protection elements inside. It is designed for applications where isolation and remote trip capability are needed, but protection is handled upstream or by a separate device. Mechanical service life is 15,000 operating cycles typical. The main circuit connects via busbar connection with front terminals — no lug terminal option on this variant. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the same footprint as the 3VA1 IEC frame 160 molded-case circuit breakers. The front terminal arrangement and busbar connection pattern match the 3VA breaker family, so it can share busbar systems and panel cutouts with the line-protection variants. Maximum power loss is 38 W at rated current — account for this in enclosure thermal calculations, especially in multi-unit panels.","metaTitle":"Siemens 3VA1110-1AA32-0HA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0HA0 switch disconnector, 100 A continuous at 40-70 °C, 3-pole, shunt trip release, IP40 front.

It also carries a shunt trip. The 3VA1110-1AA32-0HA0 is a pure switch disconnector without overcurrent protection — the two are not drop-in functional equivalents unless the circuit design already provides separate protection upstream."},{"question":"Will 3VA1110-1AA32-0HA0 drop into a panel specified for 3VA1010-2ED32-0JA0?","answer":"Physically yes — same frame size, same mounting footprint, same front terminal arrangement. But electrically no: the 3VA1110 is a switch disconnector without overcurrent protection, while the 3VA1010-2ED32-0JA0 is a circuit breaker with a TM210 release. Verify the circuit design accommodates a disconnect-only device before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-1AA32-0HA0","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/3VA1110-1AA32-0HA0 when reusing this data.
