Eaton TA1201NB1 – Frequently Asked Questions

1) Will the Eaton TA1201NB1 terminal kit fit my N-Frame Series G breaker?
The TA1201NB1 pressure terminal is built for Eaton N-frame Series G breakers in the Frame J-K size. If your breaker is a different Eaton frame (F, L, R and so on) or not a Series G, this is not the right terminal kit.
2) What conductor sizes will these 1200A Eaton pressure terminals accept?
Each pole takes three conductors sized 500 to 750 kcmil, so nine cables total across a three-pole breaker. Anything smaller than 500 kcmil or larger than 750 kcmil will not land correctly in these lugs.
3) Can I use aluminum feeders with the Eaton TA1201NB1, or copper only?
Both. These are standard Cu/Al pressure terminals, rated for copper or aluminum conductors, which matters on large 500-750 kcmil feeder runs where aluminum is often the cheaper pull.
4) I am terminating 350 kcmil on an N-frame breaker. Can I still use this terminal?
Not with this one. The TA1201NB1 lugs are sized for 500 to 750 kcmil conductors at a 1200 amp rating. For smaller feeders you want the Eaton N-frame terminal kit matched to your breaker's amp rating and wire range instead.
5) Is one Eaton TA1201NB1 enough for a three-pole 1200A breaker, or do I need one per pole?
The wire capacity is given as (3) 500-750 kcmil, which is the per-pole landing capacity for a 1200 amp connection. For a three-pole breaker you need terminal provision on all three poles, so confirm the quantity of kits against the number of poles you are terminating before you order.
6) How much room do I need in the gutter for these 1200A Eaton terminals?
Plan around a 4.4 x 3.2 x 2.5 inch terminal body plus the bending radius for three 500-750 kcmil conductors per pole, which is usually what drives the gutter space rather than the lug itself. Weight is 1.25 lb.
7) Does the Eaton TA1201NB1 include the circuit breaker?
No. TA1201NB1 is a terminal accessory only, the Cu/Al pressure lug assembly that lands feeders on an N-frame Series G breaker. The breaker itself is ordered separately.
