Description
Engineered for high-inrush applications, the Eaton FAZ-D5/1-NA-SP is a 1-pole, 5A miniature circuit breaker. It delivers reliable thermal-magnetic protection for commercial and motor control circuits. This unit installs into standard DIN rail systems and industrial control panels. It features box lug terminals and supports reverse feed capabilities for flexible wiring. Rated 10 kAIC at 277VAC, this UL 489 branch protector utilizes a D-curve trip characteristic to handle motors and transformers.Specifications

Product FAQs
7 answersWhat applications require the D-curve trip characteristic on this FAZ breaker?
The D-curve magnetic trip point operates at 10 to 20 times the rated current. It is specifically designed for high inductive loads like motors, transformers, and power supplies where significant inrush current is expected during startup.
Is the Eaton FAZ-D5/1-NA-SP approved for reverse feed wiring?
Yes, power can be supplied to either the line or the load side terminals, offering wiring flexibility inside densely packed industrial control panels.
What are the benefits of a current limiting design in this breaker?
The current limiting feature allows the breaker to clear short circuits in under half a cycle. This rapid response restricts peak let-through current, significantly reducing the thermal and magnetic stress on downstream wiring and equipment.
Can this breaker serve as a primary branch circuit protector?
Yes, because it carries a UL 489 listing, it is fully rated for primary branch circuit protection rather than just supplementary protection. This makes it suitable for motor control circuits, HVAC equipment, and control instrumentation.
How much DIN rail width is required for mounting this unit?
This single-pole breaker requires 17.7 millimeters of physical width on a standard 35mm DIN rail.
Does this miniature circuit breaker have a trip-free mechanism?
Yes. The trip-free design ensures the internal contacts will open and safely interrupt the circuit during a fault, even if the toggle handle is mechanically held or locked in the ON position.
How does the local status indicator function?
A color-coded flag indicator displays red when the contacts are closed and green when the contacts are fully open, providing a reliable visual confirmation of circuit isolation prior to servicing equipment.
