Description
Designed to support 20A commercial loads, this three-pole thermal-magnetic breaker ensures reliable circuit protection across demanding environments. It fastens securely into legacy Square D NEHB panelboards, providing an essential maintenance component for existing electrical systems. Since the modern EDB34020 substitute requires a completely different NF panelboard, utilizing this specific E-Frame unit saves significant time and labor. Rated for 14kAIC at 480Y/277V with HACR certification.

    The quality is excellent, but you need to double check when you order that the corrected one gets delivered

    Fast 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!
