Product FAQs
6 answersWhat panelboards are compatible with the EDB26030?
This breaker is designed exclusively for use in Square D NF series panelboards. It mounts directly to the panelboard bus using a bolt-on connection.
What is the difference between Square D EDB, EGB, and EJB circuit breakers?
EDB, EGB, and EJB breakers share the same physical dimensions and mount in the same Square D NF panelboards. The difference is their maximum interrupting rating. EDB is the standard tier, while EGB and EJB offer higher interrupting capacities for systems with higher available fault currents.
How many panel spaces does the EDB26030 require?
As a 2-pole circuit breaker, it requires two spaces in a Square D NF panelboard.
Is the EDB26030 HACR and HID rated?
Yes, this E-frame breaker is both HACR rated for heating, air conditioning, and refrigeration equipment, and HID rated for high-intensity discharge lighting applications.
Does this breaker feature a tripped indicator?
Yes, Square D E-frame breakers include a Visi-Trip visual 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.
What does the 600Y/347VAC voltage rating mean for this breaker?
The 600Y/347VAC rating indicates this breaker is approved for use on solidly grounded wye systems up to 600 volts, where the voltage to ground does not exceed 347 volts. It is not rated for 600V ungrounded delta systems.

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.
