B-LINE 4KES250T – Frequently Asked Questions
1) I need to change the trip rating on an existing Eaton K-frame breaker. Do I have to replace the whole breaker?
Not if the breaker carries a Digitrip 310 trip unit. On those, the rating plug sets the continuous current rating, so swapping in the 4KES250T changes the breaker to a 250A rating without pulling the breaker out for a new one. Match the frame: this plug is K-frame only.
2) Will this rating plug fit a J-frame or L-frame Eaton breaker?
No. The 4KES250T is a K-frame plug for Eaton Series C breakers with a Digitrip 310 trip unit. Rating plugs are frame-specific, so a J-frame or L-frame breaker needs the plug built for that frame, not this one.
3) Is this a fixed rating plug or an adjustable one?
Fixed. The 4KES250T is a fixed-mount plug set at 250A, so there is no dial to change the continuous rating in the field. If the panel schedule calls for a different amperage on the same K-frame breaker, order the plug at that rating instead.
