Product FAQs
5 answersWhat panelboards are compatible with the Square D EDB24030SA?
This E-Frame breaker is designed specifically for Square D NF series lighting panelboards. It uses a bolt-on connection to secure directly to the panel bus, providing a rigid and reliable connection for commercial and industrial applications.
What does the SA suffix mean in the EDB24030SA catalog number?
The SA suffix indicates that this breaker includes a factory-installed 120V AC shunt trip. This allows the breaker to be tripped remotely for emergency disconnects, fire alarm integration, or control system automation. The shunt trip is not field-installable.
Does the shunt trip on the EDB24030SA require extra panel space?
Yes. The factory-installed shunt trip accessory requires one additional pole space in the NF panelboard. Because this is a 2-pole breaker, the complete assembly will occupy three pole spaces in the panel.
Can the EDB24030SA be used on a 240V system?
Yes. While it has a maximum voltage rating of 480Y/277V AC, it is fully rated for use on 120/240V and 240V systems. When applied at 240V, the interrupting rating increases to 25kA, compared to its 18kA rating at 480Y/277V.
How does the Visi-Trip feature work on the EDB24030SA?
When the breaker trips due to an overcurrent, short circuit, or a remote shunt trip signal, the handle moves to a center position and a highly visible red indicator appears. This allows electricians to quickly identify the tripped breaker in a crowded NF panelboard.

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.
