Description
Part of the FAZ series, this two-pole 8A miniature breaker safeguards commercial and industrial motor control circuits. The unit mounts seamlessly onto standard DIN rails within industrial control panels, offering a secure fit for demanding environments. Featuring a D-curve trip profile, it accommodates the significant inrush currents generated by transformers and motors without nuisance tripping, while maintaining a 14kA interrupting capacity at 240VAC.Specifications

Product FAQs
8 answersWhat applications are best suited for the D-curve trip characteristic on this breaker?
The D-curve magnetic trip point is set between 10 and 20 times the rated current. This makes the FAZ-D8/2-NA ideal for highly inductive loads with significant inrush currents, such as motors, transformers, and power supplies, preventing nuisance tripping during startup.
Does the FAZ-D8/2-NA qualify for branch circuit protection?
Yes. The -NA suffix indicates this breaker is UL 489 listed for branch circuit protection. It can be used in applications requiring UL 489, CSA C22.2 No. 5, or IEC 60947-2 standards, unlike standard UL 1077 supplementary protectors.
How is the FAZ-D8/2-NA installed in a control panel?
This miniature circuit breaker mounts directly onto a standard 35mm DIN rail using a spring clip mechanism. It is compatible with Eaton bus connectors and feeder terminals for wiring multiple breaker arrays in industrial control panels.
Can the Eaton FAZ-D8/2-NA be reverse fed?
Yes, this circuit breaker is suitable for reverse feed applications. This allows line power to be supplied to either the top or bottom terminals, providing flexibility when wiring control panels.
Is the FAZ-D8/2-NA considered a current-limiting breaker?
Yes, it features a current-limiting design that interrupts fault currents within one half cycle. This reduces the peak let-through energy to protect downstream circuit components from damage during a short circuit.
Does this breaker have a trip-free mechanism?
Yes, the FAZ-D8/2-NA features a trip-free design. The breaker will trip internally during an overcurrent or short-circuit event even if the operating handle is physically held in the ON position.
How can I verify the contact status of the FAZ-D8/2-NA without testing the voltage?
The front face of the breaker includes a color-coded contact position indicator. It displays red when the contacts are closed and energized, and green when the contacts are open and de-energized.
Is the FAZ-D8/2-NA the same as the FAZ-D8-2-NA?
Yes, FAZ-D8-2-NA is an alternate formatting of the same Eaton catalog number used by some distributors. Both refer to the exact same 8A, 2-pole, D-curve miniature circuit breaker.
