Product FAQs
8 answersWhat does the B curve signify on the FAZ-B2/2-NA?
The B curve indicates a magnetic trip point of 3 to 5 times the rated current. It is designed for applications with low inrush currents, such as resistive loads, heaters, and long wiring runs.
What does the NA suffix mean in the FAZ-B2/2-NA catalog number?
The NA suffix indicates that the breaker is UL 489 listed for North American branch circuit protection. It can be used in applications requiring UL 489 as well as those permitting UL 1077 supplementary protection.
Can the FAZ-B2/2-NA be reverse fed?
Yes, the Eaton FAZ-NA series is suitable for reverse feed applications. Power can be supplied from either the line or load side terminals without compromising protection.
What type of DIN rail is required to mount this breaker?
This breaker mounts on a standard 35mm DIN rail. It features a quick-fastening mechanism with two lock-in positions for secure installation in control panels.
Can the box lugs on this breaker accept multiple conductors?
Yes, the terminals can accept two wires ranging from 18 AWG to 10 AWG. If terminating a single wire, the capacity expands to accept 18 AWG to 6 AWG.
Is the FAZ-B2/2-NA suitable for DC control circuits?
Yes, this breaker is dual-rated for AC and DC applications. It provides up to 10kAIC of interrupting capacity at 96VDC.
Does this breaker feature a trip-free mechanism?
Yes, it utilizes a trip-free design. The breaker will still trip and interrupt fault currents even if the toggle handle is physically held in the ON position.
How can I visually verify the contact position on the FAZ-B2/2-NA?
The breaker includes a color-coded contact position indicator on the front face. It displays red when the contacts are closed and green when they are open and isolated.
