Product FAQs
7 answersWhat does the "C" in the FAZ-C15/1-NA-SP part number indicate?
It indicates a C-curve trip characteristic. C-curve breakers are designed to trip between 5 and 10 times the rated current, making them ideal for applications with medium inrush currents like small transformers, pilot devices, and control circuits.
Is the Eaton FAZ-C15/1-NA-SP rated for branch circuit protection?
Yes, the "NA" in the catalog number indicates it is a UL 489 listed miniature circuit breaker. This means it is approved for primary branch circuit protection in North America, unlike UL 1077 supplementary protectors.
Can I use the FAZ-C15/1-NA-SP to replace an older Cutler-Hammer WMZT1C15 breaker?
Yes, the FAZ-C15/1-NA-SP is the direct, modern replacement for the obsolete Cutler-Hammer WMZT1C15 15A, 1-pole, C-curve DIN rail breaker.
Does this 15A breaker carry SWD or HACR ratings?
Yes, the FAZ-C15/1-NA-SP is both SWD (Switching Duty) rated for fluorescent lighting applications and HACR rated for use with heating, air conditioning, and refrigeration equipment.
What type of DIN rail is required to mount the FAZ-C15/1-NA-SP?
This miniature circuit breaker mounts directly onto standard 35mm DIN rail systems commonly used in industrial control panels.
Can I terminate two wires in a single lug on the FAZ-C15/1-NA-SP?
Yes, the box lugs are rated to accept two wires ranging from 18 to 10 AWG. If you are only terminating a single wire, the lugs can accept 18 to 6 AWG.
What does the "SP" suffix mean in the FAZ-C15/1-NA-SP catalog number?
The "SP" suffix indicates "Single Package." It means the breaker is packaged individually rather than in bulk quantities.
