Description
Built for demanding commercial and industrial environments, the Eaton FAZ-B32/2-NA is a 2-pole, 32-amp miniature circuit breaker. Designed for quick integration, it mounts securely onto standard 35mm DIN rail panels and accepts 18-6 AWG wiring via box lug terminals. Featuring a B-curve trip characteristic, it is optimized for resistive loads with low inrush currents, tripping at 3 to 5 times the rated current.Specifications

Product FAQs
9 answersWhat does the -NA suffix mean on the FAZ-B32/2-NA circuit breaker?
The -NA suffix indicates that this breaker is UL 489 listed for branch circuit protection in North America. This allows it to be used as a primary overcurrent protection device, unlike standard UL 1077 supplementary protectors.
What applications are best suited for the B-curve trip characteristic on this Eaton breaker?
B-curve breakers are designed to trip at 3 to 5 times the rated current. They are ideal for resistive loads or applications with very low inrush currents, such as PLC wiring, business equipment, and basic control circuits.
Can the FAZ-B32/2-NA be reverse fed during installation?
Yes, this miniature circuit breaker is reverse feed capable. Power can be supplied to either the line or load side terminals without affecting the trip mechanism or safety ratings.
What type of DIN rail is required to mount this 2-pole breaker?
This breaker is designed to snap directly onto standard 35mm DIN rail, which is commonly used in industrial control panels and automation enclosures.
Is this breaker suitable for direct current applications?
Yes, in addition to its AC ratings, this breaker is dual-rated for DC systems up to 96VDC, making it versatile for both alternating and direct current control panels.
What is the advantage of the current-limiting design in the FAZ series?
The current-limiting design interrupts fault currents within one half cycle. This rapid response reduces the peak let-through energy, providing superior protection against potential wiring or equipment damage during a short circuit.
Does this breaker provide a visual trip indication?
Yes, it features a color-coded indicator that provides immediate visual confirmation of the device status. It shows green when the breaker is OFF or tripped, and red when it is ON.
Can I use this breaker to replace a UL 1077 supplementary protector?
Yes, because this is a UL 489 listed branch circuit breaker, it can legally be used in place of a UL 1077 supplementary protector. However, a UL 1077 device cannot be used to replace a UL 489 breaker.
Are there any accessories compatible with the FAZ-B32/2-NA?
This breaker accepts a variety of field-installable accessories, including auxiliary contacts, shunt trips, and undervoltage release modules designed for the Eaton FAZ series.
