Product FAQs
6 answersCan I replace my EHB24070 with a newer EDB series breaker?
No. While EDB breakers are the modern equivalent used in newer Square D NF panelboards, they are not backwards compatible with legacy NEHB panelboards. You must use an EHB series breaker to ensure proper fit and function in an NEHB panel.
Is the Square D EHB series discontinued?
Yes, Square D has made the EHB circuit breaker series and the corresponding NEHB panelboards obsolete. Replacing a faulty breaker with an EHB24070 allows you to maintain your existing electrical distribution system without the expense of a complete panelboard upgrade.
Does the EHB24070 provide visual indication when it trips?
Yes, this breaker features a Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, the handle snaps to a midpoint position and a highly visible red indicator appears, allowing electricians to quickly identify the faulted circuit.
Can I install the EHB24070 on an energized panelboard?
No. For safety and compliance with electrical codes, you must completely de-energize the NEHB panelboard before installing or removing any bolt-on circuit breakers. Always verify the power is off using a properly rated voltage tester before beginning work.
What does the LI trip function code mean on the EHB24070?
The LI designation indicates that this thermal-magnetic breaker provides both Long-Time (L) and Instantaneous (I) trip functions. The long-time function protects against sustained overloads, while the instantaneous function provides immediate tripping during severe short circuits.
Will the EHB24070 work in a Square D I-Line panelboard?
No, the EHB24070 is a bolt-on molded case circuit breaker designed exclusively for legacy Square D NEHB panelboards. I-Line panelboards require specialized breakers with I-Line mounting brackets.

- 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!
