## Long description

The Eaton FAZ-B12/1 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. With a rated current of 12A and a B-curve tripping characteristic, this device is specifically designed to detect and interrupt overloads and short circuits in AC electrical systems. Its high breaking capacity of 15kA ensures reliable performance and enhanced safety for both residential and commercial infrastructure.
Advantages
This circuit breaker stands out due to its high breaking capacity, which allows it to handle significant fault currents safely. The B-curve characteristic is optimized for applications where low-level short-circuit protection is required, such as lighting and general-purpose circuits. Its compact 1-pole design facilitates easy installation in standard distribution boards, while the durable construction ensures long-term operational reliability and consistent protection against electrical hazards.
Suitable for
Residential lighting and power outlet circuits
Commercial building electrical distribution systems
Protection of sensitive electronic equipment
General-purpose AC electrical installations
When it may not be suitable
This device is not intended for use in DC circuits or high-inrush current applications, such as large motor starting, where a C or D curve breaker would be more appropriate. It should not be installed in environments exceeding its specified voltage or temperature ratings.
Key specifications
Number of poles: 1
Rated current: 12A
Tripping characteristic: B-curve
Breaking capacity: 15kA
System type: AC
How to use
The Eaton FAZ-B12/1 is designed for mounting on a standard DIN rail within an electrical distribution panel. Installation should be performed by a qualified electrician in accordance with local electrical codes. The device features clear terminal connections for secure wiring. Once installed, the toggle switch allows for manual operation to disconnect or reconnect the circuit as needed, while the internal mechanism automatically trips during an overload or short-circuit event.
What to consider before purchase
Verify that the 12A rating matches your circuit load requirements
Ensure the B-curve characteristic is suitable for your specific load type
Confirm the available space in your distribution board for a 1-pole device
Check that the 15kA breaking capacity meets the requirements of your electrical installation
