Product FAQs
8 answersWhat does the SA suffix mean on the EDB34030SA?
The SA suffix indicates that this breaker includes a factory-installed 110-130VAC shunt trip. This allows the breaker to be tripped remotely for emergency or control purposes. Note that the shunt trip takes up one additional pole space in the panel, so this 3-pole breaker will require 4 spaces total.
How many panel spaces does the EDB34030SA require?
This breaker requires 4 pole spaces in your NF panelboard. While it is a 3-pole breaker, the factory-installed shunt trip module occupies one additional space.
Can I install a shunt trip in the field if I already have an EDB34030?
No. According to the manufacturer, the shunt trip on Square D E-frame breakers is a factory-installed option and cannot be field-installed. You must order the EDB34030SA if a 120VAC shunt trip is required.
What panelboards is the EDB34030SA compatible with?
This breaker is exclusively designed for use in Square D NF lighting panelboards. It features a bolt-on connection that mounts directly to the panel bus, providing a secure electrical connection for commercial and industrial applications.
What voltage is required to operate the shunt trip on this breaker?
The factory-installed shunt trip requires a control voltage of 110-130VAC to operate. Applying this voltage to the shunt trip terminals will cause the breaker mechanism to open remotely.
Are there higher interrupting rating alternatives to the EDB34030SA?
Yes. If your system requires a higher interrupting capacity, the EGB34030SA provides up to 35kAIC at 480Y/277VAC, while the EJB34030SA provides up to 65kAIC at 480Y/277VAC. Both share the same physical footprint and factory-installed shunt trip features as the standard EDB model.
What does the LI trip function mean on this breaker?
The LI designation stands for Long-Time and Instantaneous. The long-time function provides thermal protection against sustained overloads, while the instantaneous function offers magnetic protection that trips the breaker immediately during a short circuit.
How do I know if the breaker has tripped during a fault?
Square D E-frame breakers feature a visual trip indicator. When the breaker trips due to an overload or short circuit, the handle moves to the center position and a high-visibility red indicator appears, allowing you to easily identify the tripped breaker in a crowded 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.
