Description
Rated for 0.5 amps, the Eaton FAZ-C0.5/1-NA-SP is a single-pole miniature circuit breaker. It serves as a drop-in replacement for the legacy WMZT1CX0. This current-limiting breaker snaps onto standard 35mm DIN rail systems, providing reliable protection for industrial control panels. It features box lug terminals that accept 18-6 AWG wiring. Delivering a 10 kAIC rating at 277VAC, this UL 489 listed breaker includes a visual trip indicator, a trip-free mechanism, and reverse feed capabilities.Specifications

Product FAQs
8 answersWhat is the trip curve for the FAZ-C0.5/1-NA-SP?
This breaker features a C-curve trip characteristic. The magnetic trip point is 5 to 10 times the rated current, making it suitable for applications with medium inrush currents such as small transformers, pilot devices, and control circuits.
Is the Eaton FAZ-C0.5/1-NA-SP rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. This allows it to be used as a primary overcurrent protective device in industrial control panels, unlike UL 1077 supplementary protectors.
What does the SP stand for in the FAZ-C0.5/1-NA-SP part number?
The SP suffix indicates Single Pack packaging. Eaton commonly uses this designation for 1-pole C and D curve miniature circuit breakers in the FAZ-NA series.
Does the FAZ-C0.5/1-NA-SP include a visual trip indicator?
Yes, FAZ-NA branch protectors feature a color-coded indicator window that provides immediate visual confirmation of the device status. Green indicates the breaker is OFF, and red indicates it is ON.
How is the FAZ-C0.5/1-NA-SP breaker mounted?
It is designed for installation on a standard 35mm DIN rail. The breaker has a compact module width of 17.7 mm per pole.
Is the FAZ-C0.5/1-NA-SP a current-limiting breaker?
Yes, the FAZ-NA series features a current-limiting design that interrupts fault currents within one half cycle. This reduces peak let-through energy to protect downstream equipment from short-circuit damage.
Can the FAZ-C0.5/1-NA-SP be reverse fed?
Yes, power to these FAZ-NA miniature circuit breakers can be fed from either the line or load side without affecting their protective functions.
Are there alternate part numbers for the FAZ-C0.5/1-NA-SP?
In some distributor systems or automation catalogs, this breaker may be listed under the alternate format FAZ-C0P5-1-NA-SP, where the P replaces the decimal point and hyphens replace the slashes.
