Providing reliable branch circuit protection, this Eaton 1-pole miniature circuit breaker is tailored for commercial, industrial, and marine applications. The unit is built to handle highly inductive loads. It easily installs into standard DIN rail panels and control enclosures. This model serves as a drop-in replacement for the legacy WMZT1D10. The D-curve trip characteristic allows for significant inrush currents without nuisance tripping. This current-limiting breaker is UL 489 listed.
What does the "D" in FAZ-D10/1-NA-SP indicate about its trip characteristics?
The "D" indicates a D-curve trip characteristic. D-curve breakers are designed to trip at 10 to 20 times the rated current. This high magnetic trip point prevents nuisance tripping in applications with high inrush currents, such as motors, transformers, and power supplies.
Is the FAZ-D10/1-NA-SP rated as a branch circuit breaker or a supplementary protector?
The FAZ-NA series is UL 489 listed, meaning it is rated for branch circuit protection. This allows it to be used as a primary overcurrent protection device, unlike UL 1077 supplementary protectors.
What do the "-NA" and "-SP" suffixes mean in the FAZ-D10/1-NA-SP catalog number?
The "-NA" designates that the breaker is designed for the North American market and meets UL 489 standards for branch circuit protection. The "-SP" indicates it is packaged as a single unit.
Can I use this breaker to replace a legacy WMZT1D10?
Yes, the FAZ-D10/1-NA-SP serves as a direct drop-in replacement for the legacy Eaton WMZT1D10 miniature circuit breaker.
What type of DIN rail is required to mount this Eaton FAZ-NA breaker?
This miniature circuit breaker mounts directly onto a standard 35mm DIN rail.
Can I terminate two wires in a single lug on the FAZ-D10/1-NA-SP?
Yes, the box lug terminals are rated to accept either a single wire from 18 to 6 AWG, or two wires from 18 to 10 AWG.
Can the FAZ-D10/1-NA-SP be reverse fed?
Yes, Eaton FAZ-NA miniature circuit breakers can be reverse fed, allowing for flexible wiring configurations in control panels and industrial enclosures.
