Description

Designed to safeguard three-phase equipment, this 7A miniature circuit breaker provides reliable protection. The D-curve trip effectively manages high-inrush currents from motors. The unit snaps onto standard 35mm DIN rails and accepts 18-6 AWG conductors. It serves as a seamless drop-in replacement for the discontinued WMZT3D07 in existing control panels. Rated 10 kAIC at 480Y/277V, this UL 489 listed device features current-limiting technology and a visual status indicator.

Product FAQs

8 answers
What does the D curve characteristic mean for the FAZ-D7/3-NA?

The D curve magnetic trip point is 10 to 20 times the rated current. This makes it ideal for applications with very high inrush currents, such as motors, transformers, and highly inductive loads, preventing nuisance tripping.

Is the Eaton FAZ-D7/3-NA rated for branch circuit protection?

Yes, it is UL 489 listed, which means it is approved for feeder and branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are allowed.

Can the FAZ-D7/3-NA be reverse fed?

Yes, this miniature circuit breaker is suitable for reverse feed applications.

Does the FAZ-D7/3-NA have a trip-free mechanism?

Yes, it features a trip-free design, meaning the breaker will still trip during an overcurrent or short circuit event even if the handle is physically held in the ON position.

What older Eaton or Cutler-Hammer part number does the FAZ-D7/3-NA replace?

The FAZ-D7/3-NA is a direct replacement for the legacy Cutler-Hammer WMZT3D07 miniature circuit breaker.

Is this breaker suitable for switching fluorescent lighting loads?

Yes, because it is rated under 20 amps, it carries an SWD (Switching Duty) rating, making it suitable for switching fluorescent lighting loads.

How does the current-limiting design of the FAZ-D7/3-NA protect circuits?

The current-limiting design interrupts fault currents within one half cycle. This fast short-circuit interruption significantly reduces the peak let-through energy that could otherwise damage downstream equipment.

What type of DIN rail is required for mounting the FAZ-D7/3-NA?

This breaker installs on a standard 35mm DIN rail using a built-in spring clip for secure mounting in control panels.
