Product FAQs
8 answersWhat does the C-curve trip characteristic mean for this Eaton breaker?
The C-curve designation indicates a magnetic trip point between 5 and 10 times the 30A rated current. This makes it suitable for medium inrush current applications like small transformers, lighting, and control circuits.
What is the difference between the FAZ-NA series and standard FAZ breakers?
The NA in the FAZ-C30/1-NA-SP part number signifies that it is a UL 489 listed device. This means it is approved for primary branch circuit protection in North America, whereas standard UL 1077 FAZ breakers are only rated as supplementary protectors.
Can I reverse feed the FAZ-C30/1-NA-SP?
Yes, this miniature circuit breaker is designed to allow power to be fed from either the line or the load side, providing flexibility when wiring DIN rail panels or industrial control panels.
How much DIN rail space does the FAZ-C30/1-NA-SP require?
This single-pole breaker requires 17.7mm of width on a standard 35mm DIN rail.
How does the current-limiting design of this breaker protect equipment?
The current-limiting design interrupts fault currents within one half cycle. This rapid response significantly reduces the peak let-through current and energy, offering superior protection against circuit damage compared to standard non-limiting breakers.
Does the FAZ-C30/1-NA-SP have a trip-free mechanism?
Yes, it features a trip-free design. This ensures the breaker will still trip and interrupt the circuit during an overcurrent or short-circuit fault even if the toggle handle is physically held in the ON position.
What does the SP suffix mean in the FAZ-C30/1-NA-SP part number?
The SP indicates single packaging. The breaker itself is identical in form, fit, and function to the standard FAZ-C30/1-NA, but it is packaged individually rather than in bulk quantities.
How do I verify the contact status of this breaker?
The breaker includes a color-coded visual indicator on the front face. It displays red when the contacts are closed and power is ON, and green when the contacts are open and isolated for OFF.
