Providing essential overcurrent protection for commercial facilities, this 80A three-pole breaker handles demanding electrical loads up to 480Y/277VAC. The bolt-on design ensures a secure connection into legacy Square D NEHB panelboards, maintaining existing infrastructure without requiring a complete system overhaul. When migrating to newer NF panelboards, the EDB34080 serves as the modern equivalent. It includes the signature Visi-Trip indicator for rapid fault identification during outages.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the Square D EHB34080 breaker?
This bolt-on circuit breaker is designed exclusively for legacy Square D NEHB panelboards. It mounts directly to the panelboard bus and is not compatible with other Square D panelboard lines.
Are Square D EHB breakers obsolete?
Yes, the EHB series is a legacy product line that is no longer manufactured by Square D. They are utilized to maintain existing NEHB panelboards without requiring a complete system overhaul.
Can I substitute a modern EDB breaker for the EHB34080?
No. Although the EDB series serves as the modern equivalent, it is engineered for newer NF panelboards and will not fit or mount into legacy NEHB panelboards. You must use an EHB series breaker to replace an existing EHB unit.
Is the EHB34080 rated for HVAC equipment?
Yes, this breaker is HACR rated, making it fully approved for use with heating, air conditioning, and refrigeration equipment in commercial distribution systems.
How does the Visi-Trip indicator work on this breaker?
The EHB34080 is equipped with Square D's Visi-Trip indicator. When a fault causes the breaker to trip, the handle moves to a center position and a highly visible red indicator appears, allowing for rapid identification of the tripped circuit in a crowded panel.
Will the breaker still trip if the handle is locked or held in the ON position?
Yes, the EHB34080 features a trip-free mechanism. This safety feature ensures the internal contacts will open the circuit during an overcurrent or short-circuit event, regardless of physical restriction on the external handle.

- 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!
