Product FAQs
6 answersWhat panelboards are compatible with the EHB14030AS?
This bolt-on circuit breaker is designed for installation in legacy Square D NEHB panelboards. It also integrates directly with Powerlink AS systems for automated lighting control and remote switching applications.
What does the AS suffix mean on the EHB14030AS catalog number?
The AS suffix designates this breaker for use with Powerlink AS systems. It includes internal mechanisms that allow for remote control switching, making it ideal for commercial lighting automation.
Is the EHB14030AS still in active production or is there a direct replacement?
The EHB series is a legacy product line. When upgrading an entire system, the ECB14030G3 serves as the modern replacement, but this requires transitioning to a newer Powerlink G3 panelboard.
What wire gauges and materials are approved for the EHB14030AS terminals?
The breaker lugs accept 14-10 AWG copper (Cu) conductors or 12-10 AWG aluminum (Al) conductors. Installers should verify the exact torque specifications printed directly on the breaker label prior to termination.
How does the trip mechanism function on this breaker?
It features a fixed thermal-magnetic trip unit. The thermal element provides long-time protection against overloads, while the magnetic element offers instantaneous protection against short circuits.
Is the EHB14030AS suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires specialized circuit protection.

- MSMike S.Verified BuyerReviewingSquare D EHB34060 - 60A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars11/21/25Fast reliable service, reasonable prices
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!
