Product FAQs
8 answersWhat does the D trip curve indicate on the FAZ-D15/3-NA?
The D-curve provides a magnetic trip point of 10 to 20 times the rated current. It is designed for applications with high inrush currents, such as motors, transformers, and power supplies, to prevent nuisance tripping.
What does the NA suffix mean in the FAZ-NA series?
The NA suffix indicates that the breaker is UL 489 listed for branch circuit protection in North America, making it suitable for feeder and branch circuits rather than just UL 1077 supplementary protection.
What are the terminal tightening torque specifications for this breaker?
The required torque depends on the wire size used. For 18 to 12 AWG wire, torque to 21 lb-in (2.4 Nm). For 10 to 8 AWG wire, torque to 25 lb-in (2.8 Nm). For 6 AWG wire, torque to 36 lb-in (4.0 Nm).
Can the Eaton FAZ-D15/3-NA be reverse fed?
Yes, power to the FAZ-NA series circuit breakers can be fed from either the line or the load side.
Is the FAZ-D15/3-NA a current-limiting circuit breaker?
Yes, it features a current-limiting design that interrupts fault currents within one-half cycle, reducing peak let-through energy to protect downstream equipment.
Can this miniature circuit breaker be used in DC circuits?
Yes, the FAZ-D15/3-NA is dual-rated for both AC and DC applications. It is rated for up to 96VDC with a 10kA interrupting capacity.
How is this circuit breaker mounted inside a control panel?
It mounts directly onto a standard 35mm DIN rail without the need for additional tools.
Does this breaker have a trip-free mechanism?
Yes, it features a trip-free design, meaning the breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
