The 3VA9143-0JD11: This terminal is a line-side or load-side lug for the 3VA6 frame. It replaces or supplements the standard breaker terminals when you need a circular-conductor interface — common in panel builds where ring-tongue or pin terminals are preferred over the breaker's box lug. The 0.7 in strip length is shorter than many universal lugs; pre-strip to that mark to avoid exposed conductor past the pressure plate. The three-unit pack covers a three-pole breaker in one shot.

Frequently asked questions
Where can I buy 3VA9143-0JD11 and how do I get a price?
This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time — no stock count or price figure is published here.
Will 3VA9143-0JD11 drop into a panel that was specified around 5SL4363-7 without rewiring?
No — the 5SL4363-7 is a 3-pole SENTRON miniature circuit breaker (MCB) on a 54 mm wide DIN-rail footprint. The 3VA9143-0JD11 is a circular conductor terminal for the 3VA6 frame, a completely different breaker platform. They are not mechanically or electrically interchangeable; the terminal does not mount on an MCB.
What is 3VA9143-0JD11's listed solid (14 - 10 AWG: 55 lb-in) on this component line?
For solid copper, the terminal is rated 14–10 AWG at 55 lb-in torque. That covers the common control-circuit and small-feeder range with one torque setting.
What compliance documentation does this brand provide for 3VA9143-0JD11 (RoHS, REACH, UL, IEC)?
As a Siemens SENTRON accessory, the 3VA9143-0JD11 is manufactured under the same compliance framework as the 3VA6 breaker family. Standard documentation includes RoHS and REACH declarations; UL and IEC listings are inherent to the 3VA6 platform. Specific certificate numbers are not carried in this listing — request them with your RFQ.
