Description
Built for demanding motor control environments, the FAZ-D7/2-NA provides robust branch circuit protection. Its D-curve trip is optimized for high-inrush inductive loads to prevent nuisance tripping. This two-pole device installs onto standard 35mm DIN rail systems. The box lug terminals accommodate 18-10 AWG wiring, making it adaptable for various industrial panel configurations. Rated 14 kAIC at 240V, this UL 489 breaker includes reverse feed capabilities and a visual trip indicator.Specifications

Product FAQs
7 answersWhat does the D trip curve mean on the FAZ-D7/2-NA?
The D curve characteristic means the magnetic trip point is set between 10 and 20 times the rated current. This prevents nuisance tripping when starting high-inrush inductive loads such as motors, transformers, and power supplies.
Is the Eaton FAZ-D7/2-NA a UL 489 or UL 1077 breaker?
The NA suffix designates this as a UL 489 listed miniature circuit breaker. This means it is fully rated for branch circuit protection, whereas standard FAZ breakers without the NA suffix are typically UL 1077 supplementary protectors.
What size DIN rail is required for mounting the FAZ-D7/2-NA?
This breaker is designed to mount directly onto standard 35mm DIN rail systems used in industrial control panels and automation equipment.
Are the terminals on the FAZ-D7/2-NA rated for dual wire connections?
Yes, the box lugs are rated for dual wire connections, accepting two conductors from 18 AWG to 10 AWG in a single terminal. For single wire connections, they accept 18 AWG to 6 AWG.
Can the FAZ-D7/2-NA be reverse fed?
Yes, Eaton FAZ-NA series breakers support reverse feed wiring. You can supply line power to either the upper or lower terminals without affecting the breaker's protective functions.
Can I use this breaker to replace an older Cutler-Hammer FAZ-D7/2-NA?
Yes. Eaton acquired Cutler-Hammer, and the FAZ-D7/2-NA is the exact same miniature circuit breaker, manufactured to the same specifications under the Eaton brand.
What protection does the LI trip function provide on the FAZ-D7/2-NA?
The LI designation stands for Long Time and Instantaneous. The thermal element provides Long Time protection against sustained overloads, while the magnetic element provides Instantaneous protection against short circuits.
