Engineered for commercial applications, the Square D EJB14015 is a 1-pole, 15A E-Frame miniature circuit breaker. It delivers robust thermal-magnetic protection. This unit installs into Square D NF panelboards using a secure bolt-on connection. It accepts 14-6 AWG copper or 12-6 AWG aluminum wire. Rated at 100 kAIC at 120V and 65 kAIC at 277V, it handles high fault currents safely. It includes a Visi-Trip indicator and carries HACR, HID, and SWD ratings.
What panelboards are compatible with the EJB14015?
This breaker is designed exclusively for use in Square D NF series panelboards. It requires a bolt-on connection to the panel bus and occupies one pole space.
Can I use the EJB14015 to replace an EDB14015 or EGB14015?
Yes. The EJB14015 shares the exact same physical E-frame footprint but offers a higher interrupting rating of 65kAIC at 277VAC. It serves as a direct, code-compliant upgrade for the 18kAIC EDB14015 and 35kAIC EGB14015.
Is the EJB14015 suitable for switching fluorescent lighting loads?
Yes, this breaker is SWD (Switching Duty) rated. This allows it to be used as a switch to control 120V or 277V fluorescent lighting circuits on a regular basis without damaging the breaker mechanism.
Does this breaker carry an HID rating?
Yes, the EJB14015 is HID (High-Intensity Discharge) rated. It is tested and approved to handle the high inrush currents typical of HID lighting fixtures without nuisance tripping.
Is the EJB14015 approved for HVAC equipment?
Yes, it is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires this specific type of circuit protection.
Can the EJB14015 be backfed for solar applications?
Yes, Square D E-frame breakers, including the EJB14015, are approved for backfeeding in AC solar applications. Note that they are not DC rated and must only be used in alternating current circuits.
Will this breaker fit in a Square D QO or Homeline panel?
No. The EJB14015 is an E-frame bolt-on breaker built specifically for commercial NF panelboards. It is physically incompatible with residential QO, NQ, or Homeline load centers.
Does the EJB14015 feature a tripped status indicator?
Yes, this breaker includes the Square D Visi-Trip indicator. When the breaker trips due to an overload or short circuit, a highly visible red indicator appears in the window to help quickly identify the faulted circuit in a crowded panel.

Exactly what we needed
Purchased the Square D EJB34060 60A 3-Pole circuit breaker for a commercial electrical application. The breaker arrived as described, was well packaged, and was the correct Square D part we needed.
Electrical components like this can sometimes be difficult to locate, so it was great to find the exact breaker without having to substitute or modify the existing equipment. Installation went smoothly and the breaker fit and operated as expected.
Very satisfied with the purchase and would order again when we need hard-to-find Square D electrical equipment.
