Description
Built for commercial and marine applications, the Eaton FAZ-D30/3-NA is a 30A, three-pole miniature circuit breaker. It delivers robust thermal-magnetic protection for circuits experiencing high inrush currents. The breaker mounts into standard DIN rail enclosures and serves as a direct replacement for the legacy WMZT3D30 model. Featuring a D-curve trip response and a 10 kAIC rating at 480Y/277VAC, it prevents nuisance tripping while maintaining strict UL 489 compliance.Specifications

Product FAQs
7 answersWhat does the D-curve trip characteristic mean for the FAZ-D30/3-NA?
The D-curve provides a high magnetic trip point of 10 to 20 times the rated current. This prevents nuisance tripping in highly inductive applications with significant inrush currents, such as motors, transformers, and power supplies.
Is the Eaton FAZ-D30/3-NA rated for branch circuit protection?
Yes, this breaker is UL 489 listed for branch circuit protection. It can also be used in applications that only require UL 1077 supplementary protection, though UL 1077 devices cannot be used in place of UL 489 breakers.
Can the FAZ-D30/3-NA replace older Cutler-Hammer miniature circuit breakers?
Yes, the FAZ-D30/3-NA serves as a direct replacement for the legacy Cutler-Hammer WMZT3D30 miniature circuit breaker.
Does the FAZ-D30/3-NA feature a trip-free mechanism?
Yes, it utilizes 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.
How is the FAZ-D30/3-NA circuit breaker mounted?
This miniature circuit breaker is designed for installation on a standard 35mm DIN rail within industrial control panels and enclosures.
How does the current-limiting design of the FAZ-NA series protect circuits?
The current-limiting design interrupts fault currents within one-half cycle of the fault. This rapid response significantly reduces the peak let-through energy that could otherwise damage downstream circuit components.
Does this breaker provide visual status indication?
Yes, the FAZ-D30/3-NA features a color-coded contact position indicator on the front of the device, showing red for ON and green for OFF to provide immediate visual confirmation of the circuit status.
