Description
Part of the legacy E-Frame series, the Square D EHB34015-1212 is a 15A, 3-pole MCCB for commercial use. It features a factory-installed 1A/1B auxiliary switch for remote monitoring. This bolt-on breaker installs into Square D NEHB panelboards. Since the NEHB line is discontinued, this serves as a vital replacement part. Modern NF panels use the EDB34015 equivalent. Rated 65kAIC at 240V and 14kAIC at 480Y/277V, it provides thermal-magnetic protection and includes a Visi-Trip indicator.Specifications

Product FAQs
5 answersWhat does the "-1212" suffix indicate on the EHB34015-1212 circuit breaker?
The "-1212" suffix signifies that the breaker is equipped with a factory-installed 1A/1B auxiliary switch. This provides one normally open and one normally closed contact for remote status signaling and monitoring.
Which panelboards are compatible with the EHB34015-1212 circuit breaker?
This breaker is designed exclusively for use in legacy Square D NEHB panelboards. Its specific bolt-on mounting configuration is not interchangeable with other Square D panelboard lines.
Is the EHB34015-1212 suitable for 480V systems with high available fault current?
While rated for 480Y/277V AC systems, its interrupting capacity is limited to 14kA at this voltage. If your system has an available fault current higher than 14kA at 480V, this breaker will not provide adequate protection and a different series must be specified.
Can the trip settings on the EHB34015-1212 be adjusted in the field?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory-calibrated for 15 amps and cannot be modified.
What safety verification is required before installing this breaker in a 480V system?
Before installation, an electrician must verify that the available fault current at the panel does not exceed 14kA. Installing this breaker in a system with higher fault current violates safety standards and risks catastrophic failure during a short circuit.

- 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!
