Eaton TA300K – Frequently Asked Questions

1) Are these Eaton Series C K-Frame terminals a circuit breaker or just the lug kit?
They're the terminal hardware only, not a breaker. The Eaton Series C K-Frame Cu/Al pressure terminals are a pressure-type line and load terminal kit that mounts to a Series C molded case breaker in the J-K frame range. If you need the breaker itself, order it separately.
2) Can I land aluminum feeder conductors on these Eaton pressure terminals?
Yes. These are Cu/Al rated pressure terminals, so they accept either copper or aluminum conductors. That matters on large feeders where aluminum is the common choice, and it means one part number covers both material calls on the job.
3) Which Eaton K-Frame terminal kit part number do I order for a 400A 3-pole breaker?
For a 400A three-pole application the part number is 3TA400K. The two-pole 400A version is 2TA400K and the four-pole is 4TA400K. At 225A there are two, three, and four pole selections as well. Pick the amperage first, then the pole count, since the lug size and quantity follow both.
4) What is the difference between Eaton TA300K and TA350K terminals?
They split on amperage. TA300K is the 225A selection and TA350K is the 400A selection, both offered without a specific pole count tied to them. If your job calls out a fixed pole count, the amperage-plus-pole part numbers such as 3TA400K are the ones to use instead.
5) Are Eaton Series C K-Frame pressure terminals UL Listed for use in a commercial panel?
UL Listed, yes. That is the certification carried on the Series C K-Frame Cu/Al pressure terminals, which is what an electrical inspector will look for on a terminal accessory in a commercial or industrial installation.
6) Do I need a special crimp tool to install these breaker terminals?
No crimper. These are pressure-type line and load terminals, so the conductor is clamped under a set screw rather than crimped. Standard hand tools handle it. Torque the lugs to the values marked on the breaker or terminal.
7) Can I use one terminal kit for both the line and the load side of the breaker?
The terminals are specified as pressure type for both line and load, so the same kit type serves both ends of a Series C J-K frame breaker. Order enough kits to cover every pole on both sides of the breaker you are terminating.
