Description
Providing UL 489 branch circuit protection, the Eaton FAZ-D1.5/1-NA-SP handles commercial and industrial motor control applications. This single-pole, 1.5-amp device installs into standard DIN rail enclosures and serves as an exact replacement for the legacy WMZT1DX1. Featuring a D-curve thermal-magnetic trip, it allows for high inrush currents typical of transformers and motors without nuisance tripping, while maintaining a 10kAIC rating at 277VAC.Specifications

Product FAQs
8 answersWhat is the trip curve for the FAZ-D1.5/1-NA-SP?
This breaker features a D-curve magnetic trip characteristic, which trips between 10 and 20 times the rated current. It is designed for highly inductive loads with high inrush currents, such as motors, transformers, and power supplies.
Does the FAZ-D1.5/1-NA-SP meet UL 489 standards for branch circuit protection?
Yes, the Eaton FAZ-NA series is UL 489 listed, making it suitable for branch circuit protection in industrial control panels and DIN rail enclosures. Because it is UL 489 listed, it can also be used in applications where UL 1077 supplementary protectors are permitted.
How is the FAZ-D1.5/1-NA-SP mounted in a control panel?
This miniature circuit breaker snaps directly onto a standard 35mm DIN rail. It features a compact module width of 17.5mm per pole to save space in panel assemblies.
Is the FAZ-D1.5/1-NA-SP a current-limiting circuit breaker?
Yes, this breaker has a current-limiting design that interrupts fault currents within one half cycle. This reduces peak let-through energy to protect downstream circuit components from potential damage.
Can power be fed from either direction on the FAZ-D1.5/1-NA-SP?
Yes, the FAZ-NA series allows power to be fed from either the line or load side terminals, providing wiring flexibility in control panel assemblies.
Does this breaker have a trip-free mechanism?
Yes, it features a trip-free design. This ensures the breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held or locked in the ON position.
What type of terminals does the FAZ-D1.5/1-NA-SP use?
It is equipped with standard box lug screw terminals that accept wire gauges from 18 AWG to 6 AWG. The captive screws are designed so they cannot be lost during installation.
What does the SP suffix mean in the FAZ-D1.5/1-NA-SP catalog number?
The SP suffix indicates that the breaker is sold in a single package rather than bulk packaging. The core breaker specifications remain identical to the standard FAZ-D1.5/1-NA.
