## Long description

The Eaton FAZ-B10/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide dependable overcurrent protection for electrical installations. This device is designed to monitor and interrupt electrical circuits in the event of an overload or short circuit, thereby safeguarding connected equipment and wiring from potential damage. Built to high manufacturing standards, it ensures consistent performance in both residential and commercial electrical distribution systems.
Advantages
This circuit breaker offers high reliability and precision in its tripping mechanism, which is essential for maintaining the integrity of electrical networks. Its compact 3-pole design allows for efficient space utilization within distribution boards. The Type B tripping characteristic makes it particularly effective for circuits with low inrush currents, providing a balanced approach to safety and operational continuity. The robust construction ensures long-term durability, while the IP20 and IP40 protection ratings offer a degree of defense against environmental factors during operation.
Suitable for
Residential lighting and power circuits
Commercial office electrical distribution
Protection of resistive loads
General purpose electrical infrastructure
This device may not be suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a Type C or Type D characteristic would be more appropriate to prevent nuisance tripping. It is also not intended for use in environments with extreme moisture or high levels of conductive dust without appropriate additional enclosure protection.
Key specifications
Rated current: 10A
Number of poles: 3
Tripping characteristic: Type B
Rated voltage: 240V
Protection rating: IP20 and IP40
The Eaton FAZ-B10/3 should be installed by a qualified electrician in accordance with local electrical codes and regulations. It is designed for mounting onto a standard DIN rail within a distribution board or consumer unit. Ensure that all terminal connections are tightened to the manufacturer's specified torque settings to prevent overheating and ensure reliable electrical contact.
What to consider before purchase
Verify that the 10A current rating matches the requirements of your specific circuit load.
Ensure the 3-pole configuration is compatible with your electrical system phase requirements.
Check that the Type B tripping characteristic is suitable for the connected equipment.
Confirm the available space in your distribution board for a 3-pole device.
Usage recommendations
Regular inspection of the circuit breaker and the distribution board is recommended to ensure that all connections remain secure and that the device is free from dust or debris. If the breaker trips, investigate the cause of the fault before resetting the switch.
