Description
Rated for 30 amps, this single-pole miniature breaker provides essential branch protection for industrial machinery. It is engineered to handle heavy inductive loads. The breaker mounts seamlessly onto 35mm DIN rails, ensuring quick integration into control panels. It is fully compatible as a replacement for the WMZT1D30 model. Operating with a 10kAIC rating at 277VAC, the D-curve mechanism prevents nuisance tripping during high inrush events. It features reverse feed capability.Specifications

Product FAQs
10 answersWhat does the D trip curve signify on the FAZ-D30/1-NA-SP?
The D-curve indicates a magnetic trip point of 10 to 20 times the rated current. This makes it ideal for applications with high inrush currents, such as motors, transformers, and power supplies, preventing nuisance tripping during startup.
Is the Eaton FAZ-D30/1-NA-SP rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are allowed.
What does the -SP suffix mean in the FAZ-D30/1-NA-SP catalog number?
The -SP suffix indicates that the breaker is sold in a single package. It shares the exact same specifications and physical dimensions as the standard FAZ-D30/1-NA.
Can the FAZ-D30/1-NA-SP be reverse fed?
Yes, this miniature circuit breaker is suitable for reverse feed applications. Power can be supplied to the breaker from either the line or load side terminals.
Does this breaker feature a trip-free mechanism?
Yes, it utilizes a trip-free design, meaning the breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
How can I visually verify the contact status of the FAZ-D30/1-NA-SP?
The breaker features a color-coded indicator on the front face. It displays red when the contacts are closed (ON) and green when the contacts are open (OFF), providing immediate visual confirmation of the device status.
Is the FAZ-D30/1-NA-SP a current-limiting circuit breaker?
Yes, it features a current-limiting design that interrupts fault currents within one-half cycle. This fast interruption reduces the peak let-through energy that could otherwise damage downstream circuit components.
Can I terminate multiple wires in a single lug on this breaker?
Yes, the box lug terminals are rated to accept either a single wire (18 to 6 AWG) or two wires (18 to 10 AWG) to facilitate clean control panel wiring.
Is the FAZ-D30/1-NA-SP SWD (Switching Duty) rated?
No. While some Eaton FAZ-NA breakers are SWD rated for switching fluorescent lighting loads, that rating only applies to models rated 20 Amps and below. Because this is a 30A breaker, it does not carry an SWD rating.
Can I add auxiliary contacts or a shunt trip to this breaker?
Yes, the FAZ-NA series supports field-installable accessories. You can mount auxiliary switches, alarm switches, or shunt trips to the side of the breaker without requiring special tools.
