Product FAQs
5 answersWhich panelboards are compatible with the EHB340901082 circuit breaker?
This bolt-on circuit breaker is designed exclusively for use in legacy Square D NEHB panelboards.
What does the 1082 suffix indicate on this Square D EHB breaker?
The 1082 suffix indicates that the breaker includes a factory-installed 120 to 277V AC shunt trip accessory. This allows the circuit to be opened remotely for safety or automation purposes.
Is the Square D EHB series obsolete, and what is the modern replacement?
Yes, the EHB series is a legacy product. The modern equivalent is the EDB series, such as the EDB34090. However, upgrading to an EDB breaker requires replacing the entire enclosure with a newer Square D NF panelboard, which is why maintaining the original EHB breaker is often preferred for existing installations.
What are the acceptable wire sizes and materials for the EHB340901082 lugs?
The lugs are dual-rated for both copper and aluminum conductors. They accept 14 AWG to 2/0 AWG copper wire, and 12 AWG to 2/0 AWG aluminum wire.
Does this breaker have an adjustable trip setting?
No, the EHB340901082 features a fixed thermal-magnetic trip unit with standard long-time and instantaneous (LI) protection functions. The trip curve cannot be adjusted in the field.

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!
