Description
Operating at up to 277VAC, this 4-amp single-pole breaker provides strict current-limiting protection for sensitive commercial and industrial loads. It installs onto standard DIN rail systems, serving as an exact replacement for the legacy FAZ-C4/1-NA model. Equipped with a C-curve thermal-magnetic trip profile, it accommodates moderate inrush currents typical of small motors and control circuits. This HACR and SWD rated unit ensures compliance for specialized switching applications.Specifications

Product FAQs
9 answersWhat type of applications is the C curve trip characteristic on this breaker suited for?
The C curve magnetic trip point operates at 5 to 10 times the rated current. This makes it ideal for applications with medium inrush currents, such as small transformers, lighting, pilot devices, and control circuits.
Is the FAZ-C4/1-NA-SP rated as a branch circuit breaker or a supplementary protector?
The FAZ-NA series is UL 489 listed, meaning it is fully rated for branch circuit protection. It can also be used in applications that only require UL 1077 supplementary protection.
Can this Eaton miniature circuit breaker be reverse fed?
Yes, the FAZ-NA series circuit breakers are suitable for reverse feed applications, allowing power to be supplied from either the line or load side.
Does this breaker have a visual trip 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.
What does the current limiting design of the FAZ-C4/1-NA-SP achieve?
The current limiting design interrupts fault currents within one half cycle. This fast short-circuit interruption reduces the peak let-through energy, offering superior protection to downstream circuit components.
What type of mounting rail is required for this breaker?
This breaker is designed for easy installation on a standard 35mm DIN rail using its built-in spring clip.
Is this 4A breaker suitable for switching fluorescent lighting loads?
Yes, FAZ-NA breakers rated 20A and below carry an SWD (switching duty) rating, making them suitable for switching fluorescent lighting loads.
Can the breaker be held closed during a fault?
No, it features a trip-free design. The breaker will trip and interrupt the circuit during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
What does the SP suffix in the FAZ-C4/1-NA-SP catalog number indicate?
The SP suffix indicates that the breaker is provided in single packaging rather than bulk packaging.
