Product FAQs
6 answersWhat does the B curve signify on the FAZ-B3/1-NA-SP?
The B curve characteristic means this breaker trips instantaneously at 3 to 5 times the rated current. It is designed for applications with low inrush currents, such as resistive loads, PLC I/O points, and control circuits.
What do the NA and SP suffixes mean in the FAZ-B3/1-NA-SP part number?
The NA suffix indicates that this is a UL 489 listed branch circuit breaker designed for the North American market, equipped with standard box lug screw terminals. The SP suffix denotes single packaging.
Is the Eaton FAZ-B3/1-NA-SP rated as a branch circuit breaker or a supplementary protector?
This breaker is UL 489 listed, meaning it is fully rated for branch circuit protection. It can also be used in applications that only require UL 1077 supplementary protection.
Can the FAZ-B3/1-NA-SP be reverse fed during installation?
Yes, this miniature circuit breaker is reverse feed capable. Power can be supplied to either the line or load side terminals.
Is the FAZ-B3/1-NA-SP a current limiting circuit breaker?
Yes, it features a current limiting design that interrupts fault currents within one half cycle. This reduces the peak let-through energy to protect downstream equipment from damage.
What is the trip-free design feature on this Eaton FAZ breaker?
The trip-free mechanism ensures that the breaker will trip under fault conditions even if the operating handle is physically held in the ON position.
