Product FAQs
8 answersWhat does the B-curve designation mean for the FAZ-B1.5/1-NA-SP?
The B-curve characteristic means 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, small wiring protection, or sensitive control circuits.
Is the Eaton FAZ-B1.5/1-NA-SP rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are permitted, but UL 1077 devices cannot be used to replace this UL 489 breaker.
Does this miniature circuit breaker have a current-limiting design?
Yes, the FAZ-B1.5/1-NA-SP is a current-limiting breaker. It interrupts fault currents within one-half cycle, reducing peak let-through energy to protect downstream equipment and wiring from damage.
Can the breaker be held in the ON position during a fault?
No, this breaker features a trip-free design. The internal mechanism will trip and open the circuit during an overload or short circuit even if the handle is physically held in the ON position.
How is the FAZ-B1.5/1-NA-SP installed in a control panel?
This miniature circuit breaker snaps directly onto a standard 35mm DIN rail. Power can be fed from either the line or load side, offering flexibility during panel wiring.
How can I verify the contact status of the breaker?
The breaker features a color-coded indicator on the front face. It displays red when the contacts are closed (ON) and green when the contacts are open (OFF), providing immediate visual confirmation of isolation.
Can auxiliary contacts be added to this breaker?
Yes, the FAZ-NA series supports field-installable accessories. Auxiliary contacts and shunt trips can be mounted to the side of the breaker for remote monitoring and control.
What does the SP suffix in the FAZ-B1.5/1-NA-SP catalog number indicate?
The SP suffix indicates single packaging. The breaker itself is the standard FAZ-B1.5/1-NA model and shares the exact same specifications.
