Product FAQs
8 answersWhat type of trip curve does the FAZ-B10/1-NA-SP feature?
This miniature circuit breaker features a B-curve trip characteristic. It is designed to trip between 3 and 5 times the rated current, making it ideal for applications with low inrush currents such as resistive loads, PLC I/O points, and computers.
Is the Eaton FAZ-B10/1-NA-SP rated for branch circuit protection?
Yes, this breaker is UL 489 listed for branch circuit protection. It can be used in applications requiring UL 489 devices, whereas UL 1077 supplementary protectors cannot.
How is the FAZ-B10/1-NA-SP breaker mounted?
This breaker mounts directly onto a standard 35mm DIN rail. It is designed for easy installation in industrial control panels and DIN rail systems.
What wire gauges are compatible with the box lug terminals on this 10A breaker?
The screw terminals accept 18 to 6 AWG when using a single wire, or 18 to 10 AWG when connecting two wires.
Does the FAZ-B10/1-NA-SP offer current limiting protection?
Yes, this breaker features a current limiting design. It interrupts fault currents within one half cycle, reducing peak let-through energy and providing superior protection for downstream circuits.
What applications are best suited for the FAZ-B10/1-NA-SP?
Due to its B-curve characteristic and UL 489 rating, it is commonly used for feeder and branch circuit protection, convenience receptacle circuits, and protecting sensitive equipment with low inrush currents.
What do the NA and SP suffixes mean in the FAZ-B10/1-NA-SP catalog number?
The NA designates it as a North American UL 489 branch circuit breaker with standard screw terminals. The SP indicates it is sold in a single package.
Does this Eaton miniature circuit breaker have a trip-free mechanism?
Yes, it features a trip-free design. The breaker will trip internally during an overcurrent or short circuit event even if the operating handle is held in the ON position.
