Product FAQs
6 answersWhat panelboards accept the EJB14025 breaker?
This bolt-on E-frame breaker is designed specifically for use in Square D NF series panelboards. It mounts directly to the panel bus using a bolted connection.
What is the difference between EDB, EGB, and EJB breakers?
The difference lies in the interrupting rating (AIC). EDB is standard interrupting (18kA at 277V), EGB is high interrupting (35kA at 277V), and EJB is extra-high interrupting (65kA at 277V). The EJB14025 provides the highest fault current protection in this specific frame class.
Can this breaker be used in 277V commercial lighting applications?
Yes, this 1-pole breaker is rated for up to 277VAC, making it suitable for commercial 277V lighting circuits. It provides a 65kA interrupting rating at this specific voltage.
What are the wire size and material requirements for the lugs?
The factory-installed lugs accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. Ensure proper torque specifications are followed during installation as outlined by Schneider Electric.
How much panel space does this 1-pole breaker require?
It occupies a single 1-inch space in a Square D NF panelboard.
Is the trip curve adjustable on this model?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
