Description
Rated 14 kAIC at 277VAC, this single-pole miniature circuit breaker delivers robust thermal-magnetic protection for motor control and industrial panels. It easily attaches to standard DIN rail systems and serves as an exact cross-reference for the legacy WMZT1C25 and FAZ-C25/1-NA models. The FAZ-C25/1-NA-SP features a C-curve trip profile, making it highly effective for managing medium startup currents. Additional benefits include reverse feed capability and a visual trip indicator.Specifications

Product FAQs
8 answersWhat applications are suitable for the C-curve trip characteristic on this breaker?
The C-curve magnetic trip point operates at 5 to 10 times the rated current. It is designed for applications with medium levels of inrush current, such as small transformers, lighting, pilot devices, and control circuits.
Is the FAZ-C25/1-NA-SP rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed, making it suitable for branch circuit protection. It can also be used in applications where UL 1077 supplementary protection is allowed.
Can the FAZ-C25/1-NA-SP be reverse fed?
Yes, Eaton FAZ-NA series circuit breakers are suitable for reverse feed applications, allowing power to be fed from either the line or load side.
Does the breaker provide visual status indication?
Yes, it includes a color-coded contact position indicator that displays red when the breaker is ON and green when it is OFF.
Is this Eaton miniature circuit breaker current limiting?
Yes, the FAZ-NA series features a current-limiting design that interrupts fault currents within one half cycle, reducing the let-through energy that can damage the circuit.
Does this breaker have a trip-free mechanism?
Yes, it features a trip-free design, meaning the breaker will trip under fault conditions even if the handle is physically held in the ON position.
What does the SP suffix in the FAZ-C25/1-NA-SP catalog number indicate?
The SP suffix indicates single packaging. It is the exact same breaker as the standard FAZ-C25/1-NA but packaged individually.
Can this breaker replace older Cutler-Hammer models?
Yes, the FAZ-C25/1-NA-SP is a direct replacement for the legacy Cutler-Hammer WMZT1C25 miniature circuit breaker.
