Eaton TA250KB – Frequently Asked Questions

1) Which Eaton breakers does the T250KB terminal kit fit?
The T250KB kit is built for Eaton type JB, KB and J-frame molded case breakers in the Series C platform, covering the Frame J-K breaker body. If your breaker is a different frame size, this kit will not land on the terminal pads.
2) What wire size can I land in the Eaton 250A Cu pressure terminal kit?
It accepts #4 AWG through 350 kcmil copper conductors, on both line and load ends. That range covers most feeder and larger branch circuit terminations at a 250A breaker. Copper only, so aluminum conductors need a different terminal.
3) Will a 250A terminal kit work on a larger breaker?
No. The kit is rated 250A, so it is matched to a 250A JB/KB J-frame application. For a higher rating, the 350 ampere option (MPN T350DA) is the one to order instead.
4) What amperage options does the Eaton Series C terminal kit come in?
Three ordering options: 250 amperes (T250KB), 350 amperes (T350DA), and TA250KB. Pick by the breaker rating you are terminating, then confirm the frame matches J-K.
5) Is the Eaton T250KB terminal kit UL Listed for a commercial panelboard job?
Yes, the kit is UL Listed, which is what an inspector looks for on a field-installed breaker terminal in panelboard and switchgear line and load terminations.
6) How much room do I need in the gutter for these Eaton pressure terminals?
Each terminal measures 1.6 in wide by 2.6 in long/deep by .9 in high, so bending space and gutter clearance should be checked against that footprint before you set the breaker.
7) Do I get both line and load terminals in the kit, or do I order two?
The kit provides line and load connections, so one kit covers both ends of the breaker for the application it is built for.
8) I need terminals for a disconnect switch, not a breaker - what should I be looking at?
The Eaton T250KB Cu pressure terminal kit is a molded case circuit breaker accessory for Eaton JB, KB and J-frame bodies, providing line and load connections for #4 AWG-350 kcmil Cu. For a disconnect switch, the ABB OZXA-800 terminal kit is the corresponding part, supplied as a replacement component for ABB OT/OS600 and OS800 switches. Confirm the switch series before ordering, since the terminal kit is specific to the device frame.
9) Is the Eaton T250KB the right terminal kit if I need more than 250A?
The T250KB itself is rated 250A. Within the same Eaton Series C Cu pressure terminal family, a 350 ampere option is offered as MPN T350DA, and TA250KB is the other 250 ampere ordering option. Note that the ABB OZXA-800 terminal kit is not an alternative here - it serves ABB OT/OS600 and OS800 disconnect switches rather than Eaton breaker frames.
