Issue:
What is the replacement for the KA36100, KA36125, KA36150, KA36175, KA36200, KA36225 and KA36250 breakers?

Product Line:
I Line Circuit breakers

Environment:
Applies to KA breakers, I-Line panelboards except HCN interior

Cause:
Cross reference for KA breakers

Resolution:
The suggested replacement breaker are:  
KA36100 = HJA36100
KA36125 = HJA36125
KA36150 = JJA36150
KA36175 = JJA36175
KA36200 = JJA36200
KA36225 = JJA36225
KA36250 = JJA36250

Breakers are rated 25kA at 600V, 65kA at 480V and 100kA at 240V.  Please note that Powerpact H and J frame breakers are functional equivalent breakers and use the same 4.5" of mounting height .

NOTE:
Due to the difference in breaker length from the Legacy breaker to the Powerpact, the mounting foot screw (retaining screw) treads into a different opening than the older circuit breakers. This is designed in this manner, and the panelboard with breakers, has been tested. The purpose of the retaining screw is to keep the breaker from being pulled away from the bus. When the installation is complete, with the breaker in place and the panelboard deadfront trim installed, the breaker will be properly mounted as designed.
