Description
Part of the FAZ-NA series, this 7A miniature circuit breaker delivers branch protection for industrial applications. It is designed to handle high-inrush inductive loads like motors and transformers. The unit mounts onto standard 35mm DIN rails and accepts 18-6 AWG wire. It serves as a drop-in replacement for the discontinued WMZT1D07 breaker in existing control panels. Rated 10 kAIC at 277 VAC, this UL 489 listed device features current-limiting technology and a visual status indicator.Specifications

Product FAQs
9 answersWhat does the D trip curve indicate on the FAZ-D7/1-NA-SP?
The D curve provides a high magnetic trip point, typically 10 to 20 times the rated current. This prevents nuisance tripping in applications with high inrush currents, such as motors, transformers, and highly inductive loads.
Is the Eaton FAZ-D7/1-NA-SP rated for branch circuit protection?
Yes. The FAZ-NA series is UL 489 listed, meaning it is approved for feeder and branch circuit protection. This differs from UL 1077 devices, which are only rated for supplementary protection.
Can I use the FAZ-D7/1-NA-SP in place of a UL 1077 supplementary protector?
Yes. Because it is a UL 489 listed branch circuit breaker, it can safely be used in applications that only require UL 1077 supplementary protection. However, a UL 1077 device cannot be used to replace a UL 489 breaker.
What size DIN rail is required to mount the FAZ-D7/1-NA-SP?
This breaker mounts directly onto a standard 35mm DIN rail. It utilizes a spring clip for secure installation in industrial control panels and branch service applications.
Can the FAZ-D7/1-NA-SP be reverse fed?
Yes, power to Eaton FAZ-NA circuit breakers can be fed from either the line or the load side without affecting the performance or protection capabilities of the device.
Is the FAZ-D7/1-NA-SP a current-limiting circuit breaker?
Yes, it features a current-limiting design that provides fast short-circuit interruption. This reduces the let-through energy and peak current, offering superior protection for the circuit and connected equipment.
What does the -SP suffix mean in the FAZ-D7/1-NA-SP catalog number?
The -SP suffix indicates single packaging. It is the exact same breaker as the standard FAZ-D7/1-NA, just packaged individually rather than in bulk quantities.
Does the FAZ-D7/1-NA-SP have a trip-free mechanism?
Yes, it features a trip-free design. This safety feature ensures the breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
Are the terminal screws on the FAZ-D7/1-NA-SP removable?
No, this breaker features standard box lug terminals with captive screws. The captive design ensures the screws cannot be lost or dropped during wiring and panel installation.
