Description
Part of Eaton's FAZ-NA series, this 1-pole miniature circuit breaker delivers reliable branch protection for commercial and industrial applications. It is optimized for resistive loads where low inrush current is expected. The breaker installs into standard 35mm DIN rail systems within industrial control panels. Its box lug terminals accept 18-6 AWG wiring. Rated at 10 kAIC for 277VAC, it features a B-curve thermal-magnetic trip mechanism that responds at 3 to 5 times the rated current.Specifications

Product FAQs
6 answersWhat does the B-curve trip characteristic mean for the FAZ-B1/1-NA-SP?
The B-curve profile means this breaker is designed to trip instantaneously at 3 to 5 times the rated current. It is ideal for resistive or slightly inductive loads where low levels of inrush current are expected, such as PLC I/O points, computers, and control circuits.
Is the FAZ-B1/1-NA-SP rated for branch circuit protection?
Yes. The NA in the part number indicates it is a UL 489 listed miniature circuit breaker. Unlike UL 1077 supplementary protectors, this UL 489 device can be used for primary branch circuit protection in industrial control panels and distribution systems.
Can I use this UL 489 breaker in place of a UL 1077 supplementary protector?
Yes. A UL 489 branch circuit breaker can generally be used in place of a UL 1077 supplementary protector, provided it meets the physical space and electrical requirements of the panel. However, a UL 1077 device cannot be used to replace a UL 489 breaker.
What type of DIN rail is required to mount this Eaton FAZ breaker?
This breaker is designed to snap directly onto a standard 35mm DIN rail. The module width is 17.5mm per pole.
Can power be fed from either the line or load side on this breaker?
Yes, the Eaton FAZ-NA series features a trip-free design that allows power to be fed from either the line or the load side without affecting the protective operation of the breaker.
What does the SP stand for in the FAZ-B1/1-NA-SP catalog number?
The SP indicates that the breaker is packaged as a single pack rather than in bulk OEM packaging. The breaker itself is identical to the standard FAZ-B1/1-NA.
