Product FAQs
6 answersWhat type of trip curve does the FAZ-B7/2-NA feature?
This miniature circuit breaker features a B-curve trip response. It is designed to trip between 3 and 5 times the rated current, making it ideal for resistive or slightly inductive loads where low inrush currents are expected.
Is the Eaton FAZ-B7/2-NA rated for branch circuit protection?
Yes, the FAZ-B7/2-NA is a UL 489 listed miniature circuit breaker. This certification means it is approved for primary branch circuit protection in industrial control panels and DIN rail systems, unlike UL 1077 supplementary protectors.
What wire sizes are compatible with the box lug terminals on this breaker?
The feed-thru box lugs accept 18 to 6 AWG for a single wire connection, or 18 to 10 AWG when connecting two wires simultaneously.
Can the FAZ-B7/2-NA be used in DC voltage applications?
Yes, in addition to its AC ratings, this thermal magnetic breaker is rated for use in DC applications up to 96VDC with a 10kA interrupting capacity.
What types of applications are best suited for the FAZ-B7/2-NA?
With its B-curve trip characteristic, this breaker is commonly used to protect sensitive electronic equipment, control circuits, and other applications with low inrush currents where rapid tripping under low fault conditions is required.
Does this Eaton FAZ series breaker include a trip-free mechanism?
Yes, it features a trip-free mechanism that ensures the breaker will trip under overcurrent or short circuit conditions even if the handle is physically held in the ON position. It also includes visual status indicators for safe maintenance.
