Description
Part of the FAZ-NA series, this 1-amp miniature breaker provides reliable overcurrent protection for commercial and industrial applications. The B-curve thermal-magnetic trip response is optimized for resistive or lightly inductive loads where short-circuit currents are low. Installation is streamlined via standard DIN rail mounting. It integrates seamlessly into industrial control panels and automation enclosures requiring compact branch circuit protection.Specifications

Product FAQs
8 answersWhat is the trip curve characteristic of the FAZ-B1/3-NA?
This breaker features a B-curve trip characteristic, meaning its magnetic trip point is 3 to 5 times the rated current. It is designed for applications with low inrush currents, such as lighting, control circuits, and pilot devices.
Is the Eaton FAZ-B1/3-NA rated for branch circuit protection?
Yes, it is a UL 489 listed miniature circuit breaker, making it suitable for branch circuit protection in industrial control panels and DIN rail applications.
Can the FAZ-B1/3-NA be reverse fed?
Yes, power can be fed from either the line or load side of this circuit breaker.
How much DIN rail space does this 3-pole breaker require?
The FAZ-NA series has a module width of 17.5 mm per pole, so this 3-pole breaker requires 52.5 mm of DIN rail space.
Does the FAZ-B1/3-NA have a visual trip indicator?
Yes, it features a color-coded contact position indicator that displays red when the breaker is ON and green when it is OFF.
Is the Eaton FAZ-B1/3-NA a current-limiting breaker?
Yes, it features a current-limiting design that interrupts fault currents quickly, reducing the peak let-through energy that can damage downstream circuits.
Can the breaker be held in the ON position during a fault?
No, it features a trip-free design, meaning the breaker will trip during an overcurrent or short circuit event even if the handle is physically held in the ON position.
Can I use a UL 1077 supplementary protector instead of the FAZ-B1/3-NA?
No, UL 1077 supplementary protectors cannot be used in place of UL 489 breakers where branch circuit protection is required by code. However, this UL 489 breaker can be used in place of a UL 1077 device.
