It drops into the same panel footprint and wiring — the only difference is the UVR coil and its associated trip mechanism. If the BOM calls for undervoltage protection, the -0BA0 is the correct variant; the -0AA0 would need a separate undervoltage relay added."},{"question":"What is 3VA1020-3ED36-0BA0's listed depth (70 mm) on this component line?","answer":"The depth is 70 mm, measured from the mounting surface to the front of the breaker body — not including any protruding handle or auxiliary trip module."},{"question":"What is 3VA1020-3ED36-0BA0's listed width (76.2 mm) on this component line?","answer":"The width is 76.2 mm, which is the standard 3-pole SENTRON 3VA10 frame width.

The only difference is the integrated undervoltage release on the -0BA0. If the panel was wired for the -0AA0 (no UVR), the -0BA0 will bolt in, but the UVR coil terminals must be connected to the control voltage that will trip the breaker on loss of power. If no UVR connection is made, the breaker functions as a standard thermal-magnetic MCCB."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1020-3ED36-0BA0","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/3VA1020-3ED36-0BA0 when reusing this data.
