Description
Built for commercial and industrial environments, the Eaton FAZ-B6/3-NA delivers robust three-phase overcurrent protection. This 6-amp breaker utilizes a B trip curve, engineered for applications with low inrush currents. Designed to replace the legacy WMZT3B06, this device mounts onto standard DIN rail systems. It is highly suitable for industrial control panels and accommodates 18-6 AWG wire through its box lug terminals.Specifications

Product FAQs
8 answersWhat does the B curve designation mean for the FAZ-B6/3-NA breaker?
The B trip curve indicates that the magnetic trip point is set to 3 to 5 times the rated current. This makes it ideal for resistive loads or applications with low inrush currents where wiring protection is the primary concern.
What does the NA suffix indicate on this Eaton circuit breaker?
The NA suffix stands for North America. It indicates that the breaker is UL 489 listed and CSA certified for branch circuit protection, unlike standard FAZ breakers which are UL 1077 recognized for supplementary protection only.
Can the Eaton FAZ-B6/3-NA be reverse fed?
Yes, all Eaton FAZ miniature circuit breakers, including the FAZ-NA series, are suitable for reverse feed applications.
What are the recommended tightening torque specifications for the box lugs?
The required torque depends on the wire size used. For 18 to 12 AWG wire, torque to 21 lb-in (2.4 Nm). For 10 to 8 AWG wire, torque to 25 lb-in (2.8 Nm). For 6 AWG wire, torque to 36 lb-in (4.0 Nm).
Are auxiliary contacts or shunt trips compatible with the FAZ-B6/3-NA?
Yes, the FAZ-NA series supports field-installable accessories, including auxiliary switches, alarm switches, and shunt trips. These can be mounted on the side of the breaker without requiring special tools.
Is the FAZ-B6/3-NA rated for direct current (DC) applications?
Yes, this breaker is dual rated for both AC and DC applications. It carries a 10kAIC interrupting rating at 96VDC, making it suitable for specific control panel DC loads.
How is the FAZ-B6/3-NA secured inside an industrial control panel?
The breaker features a spring clip design that allows it to be mounted directly onto a standard 35mm DIN rail.
Does the FAZ-B6/3-NA feature a trip-free mechanism?
Yes, it utilizes a trip-free design. This means the breaker will still trip internally during an overcurrent or short circuit event even if the operating handle is physically held in the ON position.
