Description
Built for demanding motor control and marine applications, this three-pole component provides robust branch circuit defense. The unit installs easily onto standard DIN rails within industrial control panels and serves as an exact functional replacement for the legacy WMZT3D25 model. Utilizing a D-curve thermal-magnetic profile, it allows for high inrush currents typical of transformers and motors. Current limiting capabilities and a reverse feed design add versatility to complex layouts.Specifications

Product FAQs
8 answersWhat does the D trip curve signify on the FAZ-D25/3-NA?
The D curve indicates a magnetic trip point of 10 to 20 times the rated current. It is designed for highly inductive loads with high inrush currents, such as motors, transformers, and power supplies, preventing nuisance tripping during startup.
Is the Eaton FAZ-NA series rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. This differs from standard FAZ breakers, which are UL 1077 recognized for supplementary protection only.
Can the FAZ-D25/3-NA circuit breaker be reverse fed?
Yes, Eaton FAZ-NA miniature circuit breakers are suitable for reverse feed applications, allowing power to be connected to either the line or load side terminals.
What accessories are compatible with the FAZ-D25/3-NA breaker?
The FAZ-NA series accepts a variety of field-installable accessories, including auxiliary contacts, shunt trips, undervoltage releases, busbar systems, and padlock hasps.
Is this breaker a direct replacement for Moeller FAZ series breakers?
Yes, Eaton acquired Moeller, and the FAZ-NA series is the direct continuation of the Moeller FAZ UL 489 product line. The FAZ-D25/3-NA can directly replace the equivalent legacy Moeller part.
How is the FAZ-D25/3-NA installed in a control panel?
It mounts directly onto a standard 35mm DIN rail. The breaker features a modular design with a width of 17.5mm per pole, taking up 52.5mm of total DIN rail space for this 3-pole unit.
Is the FAZ-D25/3-NA a current-limiting circuit breaker?
Yes, FAZ-NA devices feature a current-limiting design. They interrupt fault currents within one half cycle, reducing the peak let-through energy that can damage downstream circuit components.
Does this breaker have a trip-free mechanism?
Yes, it features a trip-free design, meaning the breaker will trip under fault conditions even if the operating handle is physically held in the ON position.
