Description
Engineered for single-phase commercial and industrial applications, this 3A miniature circuit breaker offers robust thermal-magnetic protection. The C-curve trip characteristic is calibrated for circuits with medium inrush currents. The breaker mounts quickly onto standard 35mm DIN rail systems and serves as a direct replacement for the legacy WMZT1C03. It is interchangeable with the standard FAZ-C3/1-NA model. Rated at 10 kAIC at 277VAC, it features a current-limiting design and SWD rating.Specifications

Product FAQs
8 answersWhat does the C-curve trip characteristic mean for the FAZ-C3/1-NA-SP?
The C-curve magnetic trip point is calibrated to trip between 5 and 10 times the 3A rated current. This makes it suitable for applications with medium inrush currents, such as small transformers, pilot devices, and control circuits.
Is the FAZ-C3/1-NA-SP rated for branch circuit protection?
Yes, the NA designation indicates this breaker is UL 489 listed for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are allowed.
What type of mounting system is required for this miniature circuit breaker?
The FAZ-C3/1-NA-SP is designed for easy installation on standard 35mm DIN rail systems commonly used in industrial control panels.
What does the -SP suffix indicate in the FAZ-C3/1-NA-SP catalog number?
The -SP suffix indicates that the breaker is shipped in a single package. It is physically and electrically identical to the standard FAZ-C3/1-NA model.
Is the Eaton FAZ-C3/1-NA-SP a current-limiting circuit breaker?
Yes, it features a current-limiting design that interrupts fault currents within one half cycle. This fast short-circuit interruption reduces let-through energy, offering superior protection for downstream components.
Can the breaker be held in the ON position during a fault?
No, this breaker features a trip-free design. The internal mechanism will trip and open the circuit during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
Is this 3A breaker suitable for switching lighting loads?
Yes, the FAZ-C3/1-NA-SP carries an SWD (Switching Duty) rating, meaning it is approved for safely switching fluorescent lighting loads on a regular basis.
Can power be fed from either direction on the FAZ-C3/1-NA-SP?
Yes, this breaker supports reverse feeding. Power can be supplied to either the line or load side terminals without affecting the device's protective functions.
