Part of the Square D E-Frame family, the EDB36100 provides 100 amps of thermal-magnetic protection for three-phase systems. It is engineered to handle commercial loads, ensuring consistent performance across branch circuit applications. Designed for seamless integration, this breaker bolts into Square D NF panelboards. It comes equipped with factory-installed lugs. With an interrupting rating of 18 kAIC at 480Y/277VAC, the HACR-rated design includes the signature Visi-Trip visual indicator.
Will this breaker fit in a Square D NQ or I-Line panelboard?
No. The EDB36100 is an E-frame breaker strictly designed for NF series lighting and distribution panelboards. NQ panels require QO or QOB breakers, while I-Line panels require bracketed I-Line breakers.
How does the EDB36100 attach to the panelboard bus?
It features a standard bolt-on connection. The breaker secures directly to the NF panelboard bus bars using captive mounting screws, providing a high-integrity electrical connection suitable for commercial and industrial environments.
Can this breaker be used on an ungrounded 480V Delta system?
No. The breaker has slash voltage ratings of 480Y/277VAC and 600Y/347VAC. It is approved only for solidly grounded wye systems where the line-to-ground voltage does not exceed 277V or 347V. It is not rated for ungrounded or corner-grounded Delta systems.
Is the EDB36100 rated for use with heating and air conditioning equipment?
Yes, this circuit breaker carries a HACR rating, making it fully certified for use with motor-driven HVAC loads such as air compressors and refrigeration equipment.
What is the difference between the EDB36100, EGB36100, and EJB36100?
While these three E-frame models share the same physical dimensions and 100A rating for NF panelboards, their short-circuit interrupting ratings (AIC) at 480Y/277VAC differ. The EDB is rated for 18kA, the EGB for 35kA, and the EJB for 65kA.
Does this breaker include a visual trip indicator?
Yes, it features Square D's Visi-Trip technology. When the breaker trips due to an overcurrent or short circuit, the handle snaps to a center position and a high-visibility red indicator appears, allowing for rapid fault identification in the panel.
Does this model provide Ground Fault Equipment Protection (GFEP)?
No, the standard EDB36100 provides only thermal-magnetic overload and short-circuit protection. It does not include built-in Ground Fault (EPD) or Arc Fault (AFI) protection modules.
Do I need to purchase terminal lugs separately?
No, the breaker comes with factory-installed mechanical lugs. These standard lugs accept both copper (14 to 2/0 AWG) and aluminum (12 to 2/0 AWG) conductors.

Breaker ordered and delivered.
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.
