Description
Engineered for commercial and industrial applications, the Eaton FAZ-B32/1-NA-SP is a 1-pole miniature circuit breaker rated for 32 amps. It mounts easily onto standard 35mm DIN rails within industrial control panels and serves as a direct replacement for the legacy WMZT1B32. The B-curve thermal-magnetic trip profile responds at 3 to 5 times the rated current, ideal for resistive loads with low inrush currents.Specifications

Product FAQs
8 answersWhich legacy Cutler-Hammer breaker does the FAZ-B32/1-NA-SP replace?
This breaker serves as a direct, drop-in replacement for the legacy Cutler-Hammer WMZT1B32 miniature circuit breaker.
What applications are best suited for the B-curve trip profile on this breaker?
The B-curve trip characteristic is designed to trip between 3 and 5 times the rated current, making it ideal for resistive loads, PLC wiring, and other applications with very low inrush currents.
Does the FAZ-NA series meet UL 489 requirements?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection, allowing it to be used as a primary overcurrent device in industrial control panels, unlike UL 1077 supplementary protectors.
How much space does this 1-pole breaker occupy on a DIN rail?
As a standard 1-pole miniature circuit breaker, it occupies a single 17.7 mm width on a standard 35mm DIN rail.
Can power be fed from either direction on the FAZ-B32/1-NA-SP?
Yes, this breaker supports reverse feed applications, meaning power can be supplied to either the line or load side terminals.
Can I terminate two wires in a single lug on this breaker?
Yes, the box lugs are rated to accept two wires ranging from 18 AWG to 10 AWG, or a single wire from 18 AWG to 6 AWG.
Does this breaker have a visual trip indicator?
Yes, it features a color-coded indicator that provides immediate visual confirmation of the device status, showing green for OFF and red for ON.
Is the FAZ-B32/1-NA-SP a trip-free design?
Yes, it utilizes a trip-free mechanism, ensuring the breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
