Part of the FAZ-NA series, this two-pole 16A miniature breaker offers current-limiting protection for commercial, industrial, and marine environments. The device mounts onto standard DIN rails and integrates seamlessly into industrial control panels. Built with a B-curve thermal-magnetic trip, it is optimized for resistive loads or applications with low inrush currents. The HACR-rated unit includes a visual status indicator and reverse feed capabilities for versatile installation.

Product FAQs
8 answers
What is the trip curve characteristic of the FAZ-B16/2-NA?
This breaker features a B curve characteristic, meaning its magnetic trip point is 3 to 5 times the rated current. It is designed for applications with low inrush currents, such as resistive loads or control circuits where wiring protection at low fault conditions is required.
Is the Eaton FAZ-B16/2-NA rated for branch circuit protection?
Yes, the -NA suffix indicates it is a UL 489 listed miniature circuit breaker. This makes it suitable for primary branch circuit protection in industrial control panels, unlike UL 1077 supplementary protectors.
Can power be fed from either direction on the FAZ-B16/2-NA?
Yes, this breaker features a reversible feed-thru design that allows power to be supplied from either the line or load side without affecting its protective functions.
What type of mounting rail is required for this circuit breaker?
The FAZ-B16/2-NA is designed to snap directly onto a standard 35mm DIN rail.
How much space does this 2-pole breaker occupy on a DIN rail?
Eaton FAZ series breakers measure 17.5 mm per pole, so this 2-pole unit will occupy exactly 35 mm of width on your DIN rail enclosure.
Does the FAZ-B16/2-NA provide visual trip indication?
Yes, it includes a color-coded indicator on the front face that displays red when the breaker is ON and green when it is OFF or tripped, providing immediate visual status for maintenance personnel.
Is this Eaton miniature circuit breaker current limiting?
Yes, it features a current-limiting design that interrupts fault currents within one half cycle. This reduces peak let-through energy and minimizes potential damage to downstream wiring and equipment.
Can I use a UL 1077 supplementary protector instead of the FAZ-B16/2-NA?
No. If your application requires UL 489 branch circuit protection, a UL 1077 device cannot be legally substituted. However, UL 489 devices like the FAZ-B16/2-NA can be used in place of UL 1077 protectors if needed.
