Product FAQs

5 answers
What is the difference between Square D EDB, EGB, and EJB circuit breakers?

These breakers belong to the same Square D E-Frame family and share identical physical dimensions for NF panelboards. The difference is their maximum interrupting rating at 480Y/277VAC. The EDB is rated for 18 kAIC, the EGB is rated for 35 kAIC, and the EJB is rated for 65 kAIC.

Can I install the EGB34025 in a Square D NQ panelboard or standard QO load center?

No. E-Frame bolt-on circuit breakers, including the EGB34025, are designed exclusively for 480Y/277VAC Square D NF panelboards. They will not fit into NQ panelboards or QO load centers.

Is the EGB34025 breaker HACR and HID rated?

Yes. This E-Frame breaker is both HACR rated for use with heating, air conditioning, and refrigeration equipment, and HID rated for switching high-intensity discharge lighting loads.

Are there higher interrupting capacity alternatives to the EGB34025?

Yes. If your electrical system requires a higher interrupting rating than the 35 kAIC offered by the EGB34025, you can use the EJB34025, which provides 65 kAIC at 480Y/277VAC. It has the exact same form factor and mounting requirements.

Can the EGB34025 be used on standard 120VAC or 240VAC systems?

Yes. Although it has a maximum voltage rating of 480Y/277VAC (at 35 kAIC), it is fully compatible with 120VAC and 240VAC systems. When used at these lower voltages, its interrupting rating increases to 65 kAIC.
