B-LINE A1KS125T1 – Frequently Asked Questions
1) What amp settings does the A1KS125T1 rating plug give me?
The A1KS125T1 is a Type KS adjustable rating plug with settings of 70, 90, 100 and 125 amps. You pick the plug for the current rating you need on the breaker, and the adjustability lets one plug cover four ampere values instead of stocking four separate parts.
2) Which breaker does the A1KS125T1 rating plug go into?
It is a rating plug for Eaton Series C molded case circuit breakers, Type KS. The plug sets the continuous current rating of the breaker's trip unit, so the breaker frame and the plug type have to match. Order by the exact part number A1KS125T1 to get the right one.
3) I need a 125 amp setting on an Eaton Series C breaker - is this the right plug?
Yes, 125A is the top setting on the A1KS125T1, and the same plug also covers 70, 90 and 100 amps. For a facility standardizing spare parts, one part number covers those four ratings across matching Type KS Series C trip units.
4) Is a rating plug the same thing as buying a new circuit breaker?
No. A rating plug changes the current rating of a breaker you already have installed, rather than replacing the breaker. If the load on a Series C breaker has changed and you need it to trip at a different ampere value, the KS plug is the part that does it. If the frame size itself is wrong for the application, a plug will not fix that and you need a different breaker.
5) Is there more than one version of the A1KS125T1 to choose from?
No options to specify. A1KS125T1 is a single configuration, ordered by that manufacturer part number, and it is the Eaton Series C Type KS adjustable rating plug.
