Description
Serving as a critical component for commercial power, the Square D EHB24050 delivers 50 amps of thermal-magnetic protection. This two-pole breaker handles standard industrial loads. It fastens into legacy Square D NEHB panelboards. For modern upgrades, this profile is replaced by the EDB24050, which requires transitioning to an NF series panelboard. Performance specs include a 14kA interrupting rating at 480Y/277VAC. It features the Visi-Trip indicator to clearly flag tripped circuits.Specifications

Product FAQs
5 answersWhich panelboards accept the EHB24050 breaker?
This breaker is designed exclusively for legacy Square D NEHB panelboards. It will not fit in modern NF or NQ series panels.
Is there a direct modern replacement for the EHB24050?
The modern equivalent is the EDB24050, but it is not backwards compatible. EDB breakers require a transition to an NF series panelboard. To maintain an existing NEHB panel, you must use an EHB series breaker.
What wire sizes are supported by the EHB24050 terminals?
The breaker lugs accept 14 AWG to 2 AWG copper conductors, or 12 AWG to 2 AWG aluminum conductors.
How can I identify if the EHB24050 has tripped?
This breaker features a Visi-Trip indicator that provides a highly visible red flag when the breaker trips, allowing for rapid identification of faulted circuits in the panel.
Is the EHB24050 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.

- 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!
