Product FAQs

8 answers
What does the B trip curve signify for the FAZ-B15/2-NA?

The B curve indicates a magnetic trip point of 3 to 5 times the 15A rated current. It is designed for resistive or slightly inductive loads where low levels of inrush current are expected, such as heaters or long control cable runs.

Is the FAZ-B15/2-NA rated for branch circuit protection?

Yes, this breaker is UL 489 listed, making it suitable for primary branch circuit protection in North America. This distinguishes it from UL 1077 devices, which are only rated as supplementary protectors.

How is the Eaton FAZ-B15/2-NA mounted in a panel?

This miniature circuit breaker snaps directly onto a standard 35mm DIN rail, which is typical for industrial control panels and automation enclosures.

What wire sizes are accepted by the terminals on this breaker?

The box lug terminals on the FAZ-B15/2-NA accept wire gauges ranging from 18 AWG to 6 AWG.

Can the FAZ-B15/2-NA be used in DC voltage applications?

Yes, in addition to its 277/480VAC ratings, this breaker is rated for up to 96VDC with a 10kAIC interrupting capacity.

Is this Eaton miniature circuit breaker reverse feed capable?

Yes, the FAZ-B15/2-NA can be reverse fed, allowing for flexible wiring configurations in control panels where the line and load connections need to be swapped.

Is this 2-pole breaker HACR rated?

Yes, it carries an HACR rating, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.

What does the NA suffix indicate in the FAZ-B15/2-NA catalog number?

The NA suffix designates that the breaker is specifically designed for the North American market, carrying a UL 489 listing for branch circuit protection rather than just an IEC rating.
