Product FAQs
6 answersCan I install this Eaton breaker in any E-Frame panelboard?
No. Although manufactured by Eaton / Cutler-Hammer, the EHB24020AS is specifically designed and listed for use in Square D Powerlink panelboards.
What wire sizes are supported by the terminal lugs?
The integrated lugs accommodate 14 AWG to 10 AWG conductors. Electricians must select the appropriate wire material and gauge to safely support the 20-amp rating.
Can this breaker be used in systems with high available fault current?
It depends on the system voltage. The EHB24020AS is rated to safely interrupt up to 18kA at 240VAC, but only 14kA at 480Y/277VAC. Verify your system's available fault current before installation.
What does the LI designation mean on this trip unit?
LI indicates that the thermal-magnetic trip unit includes fixed long-time (L) protection for thermal overloads and fixed instantaneous (I) protection for short circuits.
Is the EHB24020AS compatible with plug-on panelboards?
No, this is a strictly bolt-on circuit breaker. It must be mechanically fastened to the busbar, which is typical for commercial-grade Powerlink panelboards.
Does this breaker provide GFCI or AFCI protection?
No, the EHB24020AS is a standard thermal-magnetic breaker. It does not include ground fault (GFCI) or arc fault (AFCI) protection.

I recently ordered the incorrect breakers for a job, but I contacted Drew at SuperBreakers and he got me the correct breakers shipped out that day, which I received the next day. He sent me a label to send the wrong breakers back, and I was quickly refunded a restocking fee that I incurred for my mistake. I was able to get the breakers installed, and the power running to meet the deadline. Not to mention, the price was better than I found elsewhere. Thanks Drew!
I would definitely recommend this company if you need fast, reliable service for your electrical product needs. And I'm sure I will use them again.
Thank you SuperBreakers! Nice job Drew!
