Description
Serving specialized commercial and industrial applications, this single-pole 3A miniature breaker delivers precise thermal-magnetic protection. It fastens onto standard DIN rail systems and functions as an exact substitute for the discontinued WMZT1D03 component. Equipped with a D-curve trip profile, the device accommodates extreme inrush currents without interrupting power prematurely. This specific model features single packaging and carries an SWD rating for switching fluorescent lighting.Specifications

Product FAQs
6 answersWhat does the D in the FAZ-D3/1-NA-SP part number indicate?
The D indicates a D-curve tripping characteristic. The magnetic trip point is set between 10 and 20 times the rated current, making it ideal for high-inductive loads with significant inrush currents, such as motors and transformers.
Is the Eaton FAZ-NA series UL 489 or UL 1077 rated?
The FAZ-NA series is UL 489 listed for branch circuit protection. This allows it to be used as a primary protective device in feeder and branch circuits, unlike UL 1077 supplementary protectors.
Can the FAZ-D3/1-NA-SP be reverse fed?
Yes, Eaton FAZ-NA miniature circuit breakers are suitable for reverse feed applications, allowing power to be supplied to either the top or bottom terminals.
Is the FAZ-D3/1-NA-SP a current-limiting circuit breaker?
Yes, the FAZ-NA series features a current-limiting design. It interrupts fault currents within one half cycle, reducing the peak let-through energy to protect sensitive downstream components.
What does the -SP suffix mean on the FAZ-D3/1-NA-SP catalog number?
The -SP suffix indicates single packaging. The breaker itself is identical in form and function to the standard FAZ-D3/1-NA.
What accessories are compatible with the FAZ-D3/1-NA-SP?
The FAZ-NA series accepts field-installable accessories, including auxiliary contacts, shunt trips, and busbar connectors for multi-breaker arrays in control panels.
