Description
Constructed for three-phase commercial applications, this 8-amp device provides C-curve magnetic trip characteristics. It delivers robust branch circuit protection for industrial and marine electrical systems. The compact module secures onto standard DIN rails inside industrial control panels and equipment enclosures. Facility managers can use it as a drop-in substitute for legacy WMZT3C08 components. With a 10kA interrupting rating at 480Y/277VAC, the unit incorporates current-limiting tech.Specifications

Product FAQs
8 answersWhat does the C-curve trip characteristic mean for the FAZ-C8/3-NA?
The C-curve magnetic trip point operates at 5 to 10 times the rated current. This makes it ideal for applications with medium inrush currents, such as small transformers, lighting loads, and control circuits.
Is the Eaton FAZ-C8/3-NA rated for branch circuit protection?
Yes. The -NA suffix indicates this breaker is UL 489 listed for branch circuit protection, unlike standard FAZ breakers which are UL 1077 supplementary protectors.
What size DIN rail is required for mounting the FAZ-C8/3-NA?
This breaker is designed to mount on a standard 35mm DIN rail within industrial control panels and enclosures.
What accessories are compatible with the FAZ-NA series breakers?
The FAZ-NA series accepts field-installable accessories including auxiliary contacts, bell alarms, shunt trips, and UL 489 rated busbar systems for multi-breaker arrays.
Does the FAZ-C8/3-NA feature a trip-free design?
Yes, it includes a trip-free mechanism that ensures the breaker will trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
Is the FAZ-C8/3-NA a current-limiting circuit breaker?
Yes, its current-limiting design interrupts fault currents within one half cycle, reducing the let-through energy that can damage downstream circuit components.
Can power be fed from either direction on the FAZ-C8/3-NA?
Yes, power can be fed from either the line or load side of the breaker without affecting its protective functions.
How can I verify the contact status of the FAZ-C8/3-NA?
The breaker features a color-coded indicator on the front face that provides immediate visual confirmation of the device status, showing red for ON and green for OFF.
