Description
Engineered for precise branch circuit protection, the Eaton FAZ-B1/2-NA safeguards sensitive equipment. This 1A, two-pole miniature circuit breaker is ideal for applications where low levels of inrush current are expected. It installs onto standard 35mm DIN rails, making it a perfect fit for industrial control panels. The reverse-feed capable design allows for flexible wiring. Rated for 10 kAIC at 480Y/277VAC, it features a B-curve trip unit that responds quickly to resistive loads.Specifications

Product FAQs
7 answersWhat type of DIN rail is required to mount the FAZ-B1/2-NA?
This miniature circuit breaker mounts on a standard 35mm DIN rail.
What does the B curve designation mean for this breaker?
The B curve indicates a magnetic trip point of 3 to 5 times the rated current. It is designed for applications where low levels of inrush current are expected, such as PLC wiring, resistive loads, and control circuits.
What is the difference between the FAZ-NA and standard FAZ series?
The FAZ-NA series is UL 489 listed for branch circuit protection. The standard FAZ series is UL 1077 recognized for supplementary protection only. A UL 489 device can be used in place of a UL 1077 device, but a UL 1077 device cannot replace a UL 489 breaker.
Can the FAZ-B1/2-NA be reverse fed?
Yes, Eaton FAZ-NA miniature circuit breakers are suitable for reverse feed applications.
What is the recommended terminal torque for the FAZ-B1/2-NA?
The recommended fastening torque for the terminal screws is 7 lb-in, with a maximum allowable torque of 10.6 lb-in (1.2 Nm).
Are field-mountable accessories available for this breaker?
Yes, the FAZ-NA series is compatible with several accessories, including auxiliary switches, alarm switches, shunt trips, and lockout attachments.
Is the FAZ-B1/2-NA considered a current limiting breaker?
Yes, these devices are current limiting. They are designed to interrupt fault currents within one half cycle, which reduces peak let-through current and energy to protect downstream equipment.
