Description
Providing robust UL 489 branch circuit protection, this 16A Eaton miniature circuit breaker is tailored for industrial motor control applications. The single-package unit is engineered to manage highly inductive loads without nuisance tripping. The single-pole breaker snaps onto standard DIN rail systems and replaces the FAZ-D16/1-NA. It features a trip-free mechanism and a visual status indicator. With its D-curve trip, it accommodates startup inrush currents up to 20 times the rated amperage.Specifications

Product FAQs
8 answersWhat applications are best suited for the D-curve trip characteristic on this breaker?
The D-curve magnetic trip point operates at 10 to 20 times the 16A rated current. This high threshold prevents nuisance tripping in applications with extreme inrush currents, such as large motors, transformers, and highly inductive industrial loads.
Does the FAZ-D16/1-NA-SP meet UL 489 requirements?
Yes, the NA in the catalog number designates this as a UL 489 listed miniature circuit breaker. Unlike UL 1077 supplementary protectors, it is fully approved for primary branch circuit protection in industrial control panels.
What are the wire capacity limits for the box lug terminals?
The feed-thru box lugs can accommodate a single wire from 18 AWG up to 6 AWG. If you are landing two wires under the same lug, the capacity is restricted to 18 AWG through 10 AWG.
What type of DIN rail is required for mounting this breaker?
The breaker is designed to snap directly onto a standard 35mm DIN rail. It does not require additional mounting plates or hardware for installation in industrial control panels.
What does the -SP suffix indicate on the FAZ-D16/1-NA-SP catalog number?
The -SP suffix stands for Single Pack. It indicates the breaker is packaged individually, rather than in OEM bulk trays. The breaker itself is identical to the standard FAZ-D16/1-NA.
Is this breaker compatible with standard DIN rail busbar systems?
Yes, the FAZ-NA series is compatible with Eaton UL 489 busbar systems and bus connectors, allowing for clean and efficient power distribution across multiple breakers in a panel.
Can field-installable accessories be added to this 1-pole breaker?
Yes, the Eaton FAZ-NA frame supports a variety of modular snap-on accessories, including auxiliary contacts, bell alarms, and shunt trips, which mount directly to the side of the breaker.
Does the FAZ-D16/1-NA-SP provide current-limiting protection?
Yes, this Eaton FAZ-NA breaker features a current-limiting design. In the event of a short circuit, it interrupts the fault extremely fast, reducing the let-through energy and protecting downstream components from severe thermal and mechanical stress.
