Product FAQs
9 answersWhat does the B-curve designation mean on the FAZ-B1.5/3-NA?
The B-curve indicates that the magnetic trip point is set between 3 and 5 times the rated current. This makes it ideal for applications with low inrush currents, such as resistive loads, PLCs, and control circuits.
Is the Eaton FAZ-B1.5/3-NA rated for branch circuit protection?
Yes, the NA suffix indicates that this miniature circuit breaker is UL 489 listed for branch circuit protection, making it suitable for feeder and branch circuits unlike standard UL 1077 supplementary protectors.
Can the FAZ-B1.5/3-NA be reverse fed?
Yes, power to this Eaton FAZ-NA series circuit breaker can be fed from either the line or the load side.
How is the FAZ-B1.5/3-NA mounted in a panel?
It is designed for easy snap-on installation onto a standard 35mm DIN rail within industrial control panels or DIN rail enclosures.
Does the FAZ-B1.5/3-NA feature a trip-free mechanism?
Yes, it features a trip-free design, meaning the breaker will still trip under fault conditions even if the handle is physically held in the ON position.
How can I visually verify the contact status of the FAZ-B1.5/3-NA?
The breaker includes a color-coded indicator on the front face that provides immediate visual confirmation of the contact position, showing red for ON and green for OFF.
Is the FAZ-B1.5/3-NA considered a current-limiting circuit breaker?
Yes, it features a current-limiting design that provides fast short-circuit interruption. This reduces the peak let-through energy, helping to protect downstream sensitive components from damage.
Can the FAZ-B1.5/3-NA be used in DC control circuits?
Yes, this breaker is dual-rated for both AC and DC applications. It can safely interrupt faults in 96VDC systems, making it suitable for industrial DC control panels.
Are there field-installable accessories available for the FAZ-B1.5/3-NA?
Yes, the FAZ-NA series supports field-installable accessories such as auxiliary contacts, shunt trips, and busbar systems to expand control and monitoring capabilities.
