That shunt trip lets you remote-trip the disconnect from a safety PLC or E-stop string, which is what you want when the line-down condition demands positive isolation, not just a contactor drop. Mechanical footprint is 130 mm high, 76.2 mm wide, 70 mm deep — the standard 3VA1 frame size. Front-terminal busbar connection for the main circuit; the shunt trip and auxiliary switches are factory-installed and wired. IP40 front protection means it handles panel-side dust and incidental touch, but it is not sealed against washdown — keep it inside the enclosure.","metaTitle":"Siemens 3VA1112-1AA32-0JC0 Switch Disconnector, 125 A, 3-Pol","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0JC0 switch disconnector, 125 A rated continuous current, 3-pole, with shunt trip STL 110-127 V DC/AC and 2 HQ auxiliary switches.

The wiring difference is the shunt trip and auxiliary contacts — those are already wired on the 3VA1112-1AA32-0JC0, so if the panel was pre-wired for a shunt trip and aux switches from the 3VA1110-5EE32-0JA0, it drops in without rework."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1112-1AA32-0JC0","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/3VA1112-1AA32-0JC0 when reusing this data.
