Description
Rated for three-phase applications, the FAZ-D32/3-NA supplies 32 amps of continuous power while managing high-inrush equipment. This UL 489 listed component operates safely at 480Y/277VAC. Designed for modern industrial control panels, it mounts securely onto standard DIN rail infrastructure. The box lug terminals accept 18-6 AWG wire for flexible commercial wiring configurations. A specialized D-curve trip profile prevents nuisance tripping during motor startups.Specifications

Product FAQs
8 answersWhat does the D trip curve signify on the FAZ-D32/3-NA breaker?
The D-curve magnetic trip point is set between 10 and 20 times the rated current. This makes it ideal for highly inductive loads with significant inrush currents, such as motors, transformers, and power supplies, preventing nuisance tripping during startup.
Is the Eaton FAZ-D32/3-NA rated for branch circuit protection?
Yes. The FAZ-NA series is UL 489 listed, meaning it is fully rated for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are permitted.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the FAZ-D32/3-NA features a fixed thermal-magnetic trip unit. It provides long-time (L) and instantaneous (I) protection functions that cannot be field-adjusted.
How is the FAZ-D32/3-NA mounted and wired in a control panel?
This miniature circuit breaker mounts directly onto a standard 35mm DIN rail. It features box lug screw terminals that accept wire sizes from 18 AWG to 6 AWG.
Can the Eaton FAZ-D32/3-NA be reverse fed?
Yes, power to this circuit breaker can be fed from either the line or load side, making it suitable for reverse-feed applications in industrial control panels.
Is the FAZ-D32/3-NA a current-limiting circuit breaker?
Yes, it features a current-limiting design that interrupts fault currents within one-half cycle. This reduces peak let-through energy, providing superior protection for downstream components against short circuits.
What types of applications is the FAZ-D32/3-NA designed for?
As a UL 489 listed, D-curve breaker, it is designed for industrial control panels, motor control circuits, and equipment requiring branch circuit protection with high inrush currents, including HVAC and refrigeration (HACR) equipment.
What is the alternate catalog number FAZ-D32-3-NA?
FAZ-D32-3-NA is an alternate formatting of the exact same Eaton part number used by certain distributors. Both catalog numbers refer to the identical 32A, 3-pole, D-curve miniature circuit breaker.
