Product FAQs
5 answersWhat does the B curve designation mean for the FAZ-B3/2-NA breaker?
The B curve trip characteristic means this breaker is designed to trip between 3 and 5 times its rated current. It is ideal for resistive or slightly inductive loads where low inrush currents are expected, such as control circuits and lighting.
Is the Eaton FAZ-B3/2-NA rated for branch circuit protection?
Yes. The -NA suffix indicates this miniature circuit breaker is UL 489 listed, making it suitable for primary branch circuit protection in industrial control panels and DIN rail applications.
How is the FAZ-B3/2-NA installed in a control panel?
This miniature circuit breaker is designed for direct mounting onto a standard 35mm DIN rail, allowing for quick installation and modular arrangement in industrial control panels and equipment enclosures.
Are there bus bar accessories available for the FAZ-NA series breakers?
Yes, Eaton offers UL 489 listed bus bars and connectors, such as the Z-EB series, specifically designed to distribute power across multiple FAZ-NA miniature circuit breakers.
What type of trip mechanism does the FAZ-B3/2-NA utilize?
It uses a fixed thermal magnetic trip mechanism. The thermal portion provides long-time protection against overloads, while the magnetic portion provides instantaneous protection against short circuits.
