Description
Part of the FAZ-NA series, this 2-pole 20A miniature circuit breaker provides UL 489 branch circuit protection for commercial and industrial applications. It is specifically designed to manage highly inductive loads, such as motors and transformers, where high startup inrush currents are expected. The unit installs into standard DIN rail systems and industrial control panels. It features a current-limiting design that reduces let-through energy, alongside a visual trip indicator for safety.Specifications

Product FAQs
7 answersWhat type of loads is the D-curve trip characteristic designed for?
The D-curve trip profile is specifically designed for highly inductive loads where high startup inrush currents are expected, such as motors, transformers, and certain power supplies. It allows for 10 to 20 times the rated current before the instantaneous magnetic trip engages.
Is the FAZ-D20/2-NA rated for branch circuit protection?
Yes, the -NA suffix indicates this breaker is UL 489 listed, meaning it is approved for primary branch circuit protection in North America. This distinguishes it from UL 1077 devices, which are only rated for supplementary protection.
How much DIN rail space does the FAZ-D20/2-NA require?
This 2-pole miniature circuit breaker requires 35mm of DIN rail space, as each individual pole has a standard width of 17.5mm.
Can power be fed from either direction on this breaker?
Yes, this breaker features a feed-thru connection design that allows power to be fed from either the line or the load side, providing flexibility during panel wiring.
What accessories are compatible with the FAZ-D20/2-NA breaker?
It is compatible with Eaton FAZ-NA series accessories, including the Z-IHK-NA auxiliary contact module and FAZ-XAA-NA series shunt trips. These accessories mount directly to the left side of the breaker.
Does this breaker provide a visual trip indication?
Yes, the FAZ-NA series features a color-coded red and green indicator on the front face that provides immediate visual confirmation of the contact status and isolation function.
What is the difference between the FAZ-D20/2-NA and the standard FAZ-D20/2?
The FAZ-D20/2-NA is UL 489 listed for branch circuit protection in North America. The standard FAZ-D20/2 without the -NA suffix is a UL 1077 supplementary protector and cannot be used as a primary branch breaker.
