Both are 3-pole line-protection MCCBs, but the 3VA1110-5ED36-0AC0 uses a different trip unit and has a lower current rating — verify your load and coordination requirements before substituting."},{"question":"Will 3VA1150-6EF36-0AD0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?","answer":"Yes, the 70 mm depth and 76.2 mm width are shared across the 3VA platform, so the mounting footprint and bus-bar spacing are identical. The line and load connections are in the same positions — no backplate modification or re-drilling needed."},{"question":"Where can I buy 3VA1150-6EF36-0AD0 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution channels.
