Product FAQs

6 answers
Which panelboards are compatible with the EDB34110 circuit breaker?

This E-Frame breaker is designed specifically for Square D NF series panelboards. It secures directly to the panel bus using a bolt-on connection.

What are the direct replacements if a higher interrupting rating is required?

The EGB34110 and EJB34110 are exact dimensional upgrades for this breaker. The EGB model offers a 35kA interrupting rating, while the EJB provides 65kA at 480Y/277VAC.

Can the EDB34110 be used on a straight 480V Delta system?

No. Circuit breakers with a slash voltage rating like 480Y/277VAC are intended strictly for solidly grounded wye systems. The line-to-ground voltage must not exceed the lower value of 277V.

Can I install this E-Frame breaker in an NQ or I-Line panelboard?

No. NQ panelboards are rated up to 240V and require QO or QOB series breakers. I-Line panelboards require breakers with specific plug-on jaw assemblies. The EDB series is exclusively for NF panels.

How many mounting spaces does this breaker occupy in an NF panel?

The EDB34110 requires three standard circuit spaces, occupying one space per pole along the NF panelboard bus.

Does this breaker require a separate lug kit for installation?

No. Mechanical load-side lugs are factory-installed and included with the breaker. They are dual-rated for terminating either copper or aluminum conductors.
