Product FAQs
6 answersWhat does the "AS" suffix indicate on the EHB34020AS?
The AS suffix designates that this breaker is compatible with Square D Powerlink AS remote-controlled systems. It allows the breaker to be operated remotely via a Powerlink AS control module for automated facility lighting and power management.
Will the EHB34020AS fit in a modern Square D NF panelboard?
No. EHB series breakers are legacy components designed exclusively for older NEHB panelboards. Modern NF panelboards require EDB, EGB, or EJB series breakers.
Can I use a standard EHB34020 in place of the EHB34020AS?
Yes, but only if you do not need remote switching capabilities. A standard EHB34020 will physically fit the NEHB panelboard and provide identical overcurrent protection, but it cannot interface with the Powerlink AS control module.
Is the EHB34020AS still manufactured by Schneider Electric?
No. The NEHB panelboard line and the associated EHB circuit breakers are obsolete and have been discontinued by the manufacturer. Replacements must be sourced from legacy inventory.
What is required to utilize the remote control features of this breaker?
To use the automated switching functions, the breaker must be installed in an NEHB panelboard equipped with a Powerlink AS control bus and a compatible power interface module.
Can I install this breaker in a live panel?
No. For safety and compliance with electrical codes, the panelboard must be completely de-energized before installing or removing any bolt-on circuit breaker.

- 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!
