Description
Providing reliable branch circuit protection, the FAZ-D32/1-NA-SP handles highly inductive loads like motors and transformers. This 32-amp, single-pole unit operates at up to 277VAC. Installation into industrial control panels is streamlined via standard DIN rail mounting. It serves as an exact replacement for the discontinued WMZT1D32 model. Featuring a D-curve response, it allows for significant initial current surges without nuisance tripping.Specifications

Product FAQs
6 answersWhat applications are best suited for the D-curve trip characteristic on this breaker?
The D-curve magnetic trip point is 10 to 20 times the rated current. This prevents nuisance tripping, making it ideal for highly inductive loads with high inrush currents like motors, transformers, and power supplies.
What does the SP suffix mean in the FAZ-D32/1-NA-SP catalog number?
The SP suffix indicates single packaging. It is the standard designation for Eaton 277VAC single-pole FAZ-NA series breakers when packaged individually.
Can the FAZ-D32/1-NA-SP replace older Cutler-Hammer WMZT series breakers?
Yes, this breaker serves as an exact, direct replacement for the discontinued WMZT1D32 miniature circuit breaker.
Is the Eaton FAZ-D32/1-NA-SP a current-limiting circuit breaker?
Yes, it is a current-limiting device. It is designed to interrupt fault currents within one-half cycle, which reduces peak let-through energy and provides superior protection for downstream circuit components.
Does this miniature circuit breaker meet UL 489 requirements?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can be used for feeder and branch circuits, unlike UL 1077 supplementary protectors.
What type of DIN rail is required for mounting this breaker?
The breaker is designed to snap directly onto a standard 35mm DIN rail. It is also compatible with Eaton busbar accessories for wiring multiple miniature circuit breaker arrays in control panels.
