Description
Part of the FAZ-NA series, this three-pole miniature breaker provides robust branch circuit protection for commercial and industrial applications. It mounts easily onto standard DIN rail systems, making it ideal for high-density control panels. With a 10kA short-circuit current rating at 480Y/277VAC, the unit incorporates current-limiting technology and a trip-free mechanism to safeguard wiring and sensitive electronics from overcurrent events.Specifications

Product FAQs
8 answersWhat does the B trip curve indicate on the FAZ-B7/3-NA?
The B curve characteristic means the breaker is designed to trip between 3 and 5 times the rated current. This makes it ideal for applications with low inrush currents, such as sensitive control circuitry and resistive loads.
Is the Eaton FAZ-B7/3-NA rated for branch circuit protection?
Yes, the -NA suffix indicates this breaker is UL 489 listed for branch circuit protection. This allows it to be used as a primary branch circuit device, unlike UL 1077 supplementary protectors.
What type of DIN rail is required to mount this breaker?
The FAZ-B7/3-NA is designed to snap directly onto a standard 35mm DIN rail.
Can power be fed from either direction on this breaker?
Yes, this breaker is reverse feed capable. Power can be supplied to either the line or load side terminals without affecting the trip characteristics.
How does the visual status indicator work on this breaker?
The breaker features a color-coded indicator on the front face that provides immediate visual confirmation of the contact status. It displays green when the breaker is OFF and red when it is ON.
Can I terminate two wires in a single lug on this breaker?
Yes, the box lug terminals are rated to accept two wires ranging from 18 to 10 AWG. When terminating a single wire, the terminals accept 18 to 6 AWG.
Is the FAZ-B7/3-NA considered a current limiting breaker?
Yes, it features a current limiting design that provides fast short circuit interruption. This reduces the peak let-through current and energy, offering superior protection for downstream components.
Can this breaker be used in DC control circuits?
Yes, it is dual rated for both AC and DC applications. It carries a DC interrupting rating of 10kA at up to 96VDC.
