Description
Delivering reliable branch circuit protection, the Eaton FAZ-NA series features a current-limiting design for industrial applications. This 40A device utilizes a C-curve trip mechanism to handle moderate inrush currents. Designed for seamless integration, it snaps onto standard 35mm DIN rail systems within control panels. Facility managers can utilize this unit as an exact substitute for the discontinued WMZT2C40.Specifications

Product FAQs
8 answersWhat does the C curve designation mean on the FAZ-C40/2-NA?
The C curve indicates a magnetic trip point of 5 to 10 times the 40A rated current. This makes it ideal for applications with medium inrush currents, such as small transformers, lighting, and pilot devices.
Is the Eaton FAZ-C40/2-NA rated as a UL 489 or UL 1077 device?
This breaker is a UL 489 listed industrial miniature circuit breaker, meaning it is approved for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are permitted.
How is the FAZ-C40/2-NA circuit breaker mounted in a control panel?
It is designed for installation on a standard 35mm DIN rail. Power to the circuit breaker can be fed from either the line or load side, offering flexibility during panel wiring.
Is the FAZ-C40/2-NA a current-limiting circuit breaker?
Yes, it features a current-limiting design that interrupts fault currents within one half-cycle. This reduces peak let-through energy, offering superior protection for downstream components and reducing potential circuit damage.
Can I add auxiliary contacts or shunt trips to the FAZ-C40/2-NA?
Yes, the Eaton FAZ-NA series supports field-installable accessories. You can retrofit auxiliary contacts, shunt trips, and bus bar connectors directly to the breaker for advanced control and monitoring.
Does the FAZ-C40/2-NA provide visual trip indication?
Yes, it includes a color-coded indicator that provides immediate visual confirmation of the device status. Green indicates the breaker is OFF, and red indicates it is ON.
Can the FAZ-C40/2-NA be used in DC circuits?
Yes, this breaker is dual-rated for both AC and DC applications. It supports up to 96VDC with a 10kAIC interrupting rating, making it suitable for various industrial control environments.
Does the FAZ-C40/2-NA feature a trip-free mechanism?
Yes, it utilizes a trip-free design. This safety feature ensures the breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
