The Siemens 3VM9113-0JC12 is a circular conductor terminal TA2.1 designed for 25 to 150 mm² cable, with an integrated auxiliary conductor voltage tap. It comes as a set of three units and is an accessory for the 3VM10 and 3VM11 molded case circuit breaker families.
The 25 to 150 mm² range covers the heavy lug sizes you'd find on main feeders or large motor circuits — think 200 A to 600 A class cable, depending on insulation type and ambient. The auxiliary voltage tap means you don't need a separate splice or terminal block to pick off control power upstream of the breaker; it's a clean one-piece connection that saves a couple of inches of rail space and one less termination to torque-check. Group Code P360 and Product Group 5384 are Siemens internal cataloging codes. They don't change fit, but they confirm this terminal belongs to the 3VM accessory family — useful when cross-referencing a BOM line or checking compatibility with a panel layout drawing.
Note the Product class B designation: return restricted, meaning Siemens requires you to contact your Siemens partner or contact for return authorizations. This doesn't affect ordering — it's a logistics flag for warranty or credit returns, not a supply constraint.
