Description
Ideal for upgrading older control panels, this 1-pole 25A miniature circuit breaker serves as an exact replacement for the discontinued WMZT1D25. It delivers reliable UL 489 branch circuit protection for commercial and industrial motor control applications. The breaker features a D-curve trip profile to accommodate the high inrush currents typical of inductive loads. It easily installs into standard DIN rail systems and includes a visual status indicator for quick operational checks.Specifications

Product FAQs
6 answersWhat does the D trip curve signify on the FAZ-D25/1-NA-SP?
The D curve indicates a magnetic trip point of 10 to 20 times the rated current. This makes it ideal for highly inductive loads, such as motors, transformers, and power supplies, where high inrush currents are expected without causing nuisance tripping.
Can the FAZ-D25/1-NA-SP be used for branch circuit protection?
Yes. The NA in the part number indicates it is a UL 489 listed miniature circuit breaker, which means it is approved for branch circuit protection in North America, unlike UL 1077 supplementary protectors.
What does the SP suffix mean in the FAZ-D25/1-NA-SP catalog number?
The SP suffix stands for Single Packaging. It indicates that this single-pole breaker is packaged and sold individually rather than in bulk multi-packs.
What type of DIN rail is required for installing this breaker?
The FAZ-D25/1-NA-SP snaps directly onto a standard 35mm DIN rail, which is the industry standard for industrial control panels and automation equipment.
Is the FAZ-D25/1-NA-SP a current-limiting circuit breaker?
Yes. It features a current-limiting design that interrupts fault currents within one-half cycle. This reduces the peak let-through energy, providing superior protection for downstream circuit components.
Does this breaker provide a visual indication of its contact status?
Yes, the FAZ-NA series includes a color-coded indicator on the front of the device. It displays red when the contacts are closed and power is flowing, and green when the contacts are open and isolated.
