Description
Offering reliable single-phase protection, the Eaton FAZ-B7/1-NA-SP is a 7-amp miniature circuit breaker tailored for commercial use. It employs a B trip curve, optimized for resistive loads where low fault conditions are anticipated. This model serves as a substitute for the FAZ-B7/1-NA and installs easily onto 35mm DIN rail systems. The compact footprint is ideal for high-density industrial control panels, accepting 18-6 AWG wiring.Specifications

Product FAQs
6 answersWhat applications are best suited for the B trip curve on the FAZ-B7/1-NA-SP?
The B curve is designed for applications where low levels of inrush current are expected. This makes it ideal for protecting sensitive control circuits, small transformers, and resistive loads where potential wiring damage could occur at low fault conditions.
Is the FAZ-B7/1-NA-SP rated for branch circuit protection?
Yes, the NA suffix indicates this breaker is UL 489 listed for branch circuit protection. It can be used in place of UL 1077 supplementary protectors, but UL 1077 devices cannot be used in its place.
What does the SP suffix mean in the FAZ-B7/1-NA-SP catalog number?
The SP suffix indicates that the breaker is packaged as a single unit, or Single Pack, rather than in bulk quantities. The breaker itself is identical to the FAZ-B7/1-NA.
What size DIN rail is required for mounting this breaker?
The FAZ-B7/1-NA-SP is designed to snap directly onto a standard 35 mm DIN rail, making it compatible with most industrial control panels and automation enclosures.
How are conductors terminated on the FAZ-B7/1-NA-SP?
This breaker features standard box lug screw terminals that accept multiple conductors. The terminals are rated for wire gauges from 18 AWG to 6 AWG.
Does this Eaton FAZ breaker offer current limiting protection?
Yes, Eaton FAZ-NA devices are current limiting. They interrupt fault currents within one half cycle, which reduces peak let-through current and energy to provide superior protection for downstream components.
