## Long description

The EATON FAZ-B1 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. With a high rated breaking capacity of 15kA, this device is specifically designed to handle demanding electrical environments, ensuring consistent performance and safety in both industrial and commercial applications. It serves as a critical component for managing overcurrent and short-circuit risks, maintaining the integrity of your electrical infrastructure.
Advantages
This miniature circuit breaker offers exceptional reliability due to its high breaking capacity, which allows it to safely interrupt significant fault currents. The B-characteristic tripping curve is optimized for applications where low-level short-circuit protection is required, such as lighting and heating circuits. Its compact 1-pole design facilitates efficient use of space within distribution boards, while the robust construction ensures long-term operational stability and compliance with rigorous international safety standards.
Suitable for
Industrial electrical distribution systems
Commercial building power management
Lighting circuit protection
Heating and ventilation control systems
General electrical infrastructure requiring high-capacity fault protection
When it may not be suitable
This device is not intended for use in circuits with high inrush currents, such as those powering large motors or transformers, where a C or D characteristic breaker would be more appropriate. It is also not suitable for multi-phase applications unless specifically configured as part of a larger, compatible assembly.
Key specifications
Number of poles: 1
Rated breaking capacity: 15kA
Tripping characteristic: B
Mounting type: DIN rail
Protection type: Overcurrent and short-circuit
How to use
The EATON FAZ-B1 should be installed by a qualified electrician in accordance with local electrical codes. It is designed for mounting onto a standard DIN rail within an electrical distribution board. Ensure that the supply voltage and current ratings of the circuit match the specifications of the breaker before installation. Once mounted, connect the incoming supply to the top terminal and the outgoing load to the bottom terminal, ensuring all connections are tightened to the manufacturer's specified torque settings.
What to consider before purchase
Verify that the B-characteristic is suitable for your specific load type
Ensure the 15kA breaking capacity meets the requirements of your installation's fault level
Check available space in your distribution board for a 1-module device
Confirm compatibility with existing DIN rail systems
Usage recommendations
Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic testing of the tripping mechanism to ensure continued operational safety and compliance with maintenance schedules.
