Product FAQs
8 answersWhat panelboards are compatible with the Square D EDB14040?
This E-frame breaker is designed specifically for Square D NF series panelboards. It will not fit in NQ, QO, or Homeline load centers.
What is the difference between the EDB14040, EGB14040, and EJB14040?
These breakers share the same physical footprint and NF panelboard compatibility, but differ in their maximum interrupting ratings at 277VAC. The EDB14040 is rated at 18kAIC, the EGB14040 at 35kAIC, and the EJB14040 at 65kAIC.
Is the EDB14040 rated for HVAC equipment?
Yes, all Square D EDB, EGB, and EJB circuit breakers are UL Listed as HACR type, making them suitable for heating, air conditioning, and refrigeration applications that require this specific rating.
Can I use the EDB14040 to replace an older EHB breaker in an NEHB panelboard?
No, the EDB series is not backwards compatible with legacy NEHB panelboards. The EDB14040 is designed exclusively for modern Square D NF panelboards.
Does the EDB14040 include a Visi-Trip indicator?
Yes, Square D E-frame breakers feature the Visi-Trip indicator. When the breaker trips, the handle snaps to a midpoint position and a highly visible red indicator appears, making it easy to identify the tripped circuit in a crowded panel.
How does the EDB14040 mount into the panelboard?
This is a bolt-on circuit breaker. It secures directly to the bus bar of a Square D NF panelboard using a bolted connection, providing a stable and secure installation for commercial and industrial applications.
What is the difference between the EDB14040 and the EDB14040EPD?
The standard EDB14040 provides thermal-magnetic overload and short-circuit protection. The EDB14040EPD includes an Equipment Protection Device (EPD) that adds 30mA ground fault protection for equipment. Additionally, EPD breakers require two pole spaces in the panelboard, whereas the standard EDB14040 only requires one.
Can the EDB14040 be locked out for maintenance?
Yes, Square D offers field-installable padlock attachments for E-frame breakers. These accessories allow the breaker handle to be secured in the OFF position to comply with lockout/tagout (LOTO) safety procedures.

Called in as a last attempt because my regular supplier didn't have any of these in stock. I got a very friendly salesperson, and they sold me a new breaker for less than half of what my standard supplier would have. Definitely going here again.
