Product FAQs
6 answersWhat panelboards are compatible with the Square D EDB26040?
The EDB26040 is an E-frame circuit breaker designed exclusively for use in Square D NF panelboards. It is not compatible with NQ or QO series panelboards.
What is the difference between the EDB26040, EGB26040, and EJB26040?
All three are 40A, 2-pole E-frame breakers for NF panelboards, but they offer different interrupting ratings. The EDB is the standard tier (18kA at 480Y/277VAC), the EGB is the high-interrupting tier (35kA at 480Y/277VAC), and the EJB is the extra-high tier (65kA at 480Y/277VAC).
Is the EDB26040 circuit breaker HACR rated?
Yes, this E-frame breaker is HACR rated, meaning it is approved for branch circuit protection of heating, air conditioning, and refrigeration equipment.
Can the EDB26040 be mounted on a standard DIN rail?
No, this is a bolt-on circuit breaker. It is designed to bolt directly to the interior busbars of a Square D NF panelboard and cannot be installed on a DIN rail.
Does the EDB26040 include equipment ground fault protection?
No, this model features standard thermal-magnetic trip functions for overload and short-circuit protection. Square D E-frame breakers that include 30mA equipment ground fault protection will have an EPD suffix in the catalog number.
Does the EDB26040 feature a visual trip indicator?
Yes, Square D E-frame breakers include the Visi-Trip indicator. When the breaker trips, the handle moves to a center position and a red indicator appears, allowing electricians to quickly identify the faulted circuit in a crowded panel.
