Description
Built for commercial applications, this 1A miniature circuit breaker provides robust branch protection. The C-curve trip characteristic makes it ideal for medium inrush loads, such as lighting circuits and pilot devices. The single-pole unit mounts onto standard 35mm DIN rail systems and industrial control panels. It easily replaces older WMZT1C01 and FAZ-C1/1-NA breakers. Rated for 10 kAIC at 277VAC, the breaker utilizes thermal-magnetic technology to quickly interrupt electrical faults.Specifications

Product FAQs
9 answersWhat does the C curve trip characteristic mean for the FAZ-C1/1-NA-SP?
The C curve indicates a medium magnetic trip point of 5 to 10 times the rated current. It is designed for applications with medium inrush currents, such as small transformers, pilot devices, control circuits, and lighting.
Is the Eaton FAZ-C1/1-NA-SP rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are permitted.
How is the FAZ-C1/1-NA-SP circuit breaker mounted?
This miniature circuit breaker mounts directly onto a standard 35mm DIN rail, making it suitable for industrial control panels and feeder applications.
Is the FAZ-C1/1-NA-SP a current limiting circuit 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 the circuit from damage.
Can power be fed from either direction on the FAZ-C1/1-NA-SP?
Yes, power to this circuit breaker can be fed from either the line or the load side.
What does the SP suffix indicate in the FAZ-C1/1-NA-SP catalog number?
The SP suffix indicates that the breaker comes in a single package. The core breaker is identical to the standard FAZ-C1/1-NA.
What wire sizes are compatible with the box lugs on this 1A breaker?
The screw clamp terminals accept 18 to 6 AWG for a single wire, or 18 to 10 AWG when connecting two wires.
Does the FAZ-C1/1-NA-SP have a visual status indicator?
Yes, it features a color-coded indicator that provides immediate visual confirmation of the device status, showing red for ON and green for OFF.
Does this breaker feature a trip-free mechanism?
Yes, the FAZ-NA series utilizes a trip-free design. The breaker will trip under fault conditions even if the handle is held in the ON position.
