Description
Part of the FAZ-NA series, this 3A miniature breaker provides reliable branch protection. It manages inductive loads where significant startup currents are expected. The unit mounts onto 35mm DIN rails, making it an ideal fit for control panels and enclosures. It serves as a direct replacement for the WMZT2D03 model. Rated for 10kAIC at 480Y/277VAC, it features a D-curve thermal-magnetic trip that handles high inrush currents. It includes a visual trip indicator.Specifications

Product FAQs
8 answersWhat type of trip curve does the FAZ-D3/2-NA feature?
This breaker features a D-curve thermal-magnetic trip profile. It is designed to handle high inrush currents, typically 10 to 20 times the rated current, making it ideal for highly inductive loads.
Is the FAZ-D3/2-NA rated for branch circuit protection?
Yes, the Eaton FAZ-NA series is UL 489 listed, meaning it is fully rated for branch circuit protection in industrial control panels and enclosures.
Can I use the FAZ-D3/2-NA to replace an older WMZT2D03 breaker?
Yes, the FAZ-D3/2-NA serves as a direct replacement for the legacy Eaton WMZT2D03 miniature circuit breaker.
What type of mounting rail is required for this miniature circuit breaker?
This breaker is designed to snap directly onto a standard 35mm DIN rail for quick installation in control panels and equipment enclosures.
What wire sizes are accepted by the box lug terminals on this breaker?
The terminals accept 18 to 6 AWG when wiring a single conductor, or 18 to 10 AWG when connecting two wires.
Does this breaker support both AC and DC voltage applications?
Yes, it is rated for use in both alternating current systems up to 480Y/277VAC and direct current systems up to 96VDC.
Does the FAZ-D3/2-NA include a visual trip indicator?
Yes, this miniature circuit breaker includes a visual trip indicator to help operators quickly identify a faulted circuit within a crowded panel.
Can this breaker be used with a bus bar system?
Yes, the FAZ-NA series is compatible with Eaton UL 489 bus bar connectors, such as the Z-EB series, for streamlined power distribution across multiple breakers.
