## Summary description

The Eaton FAZ-B25/2 is a high-performance 2-pole miniature circuit breaker designed for reliable overcurrent and short-circuit protection. With a 25A rated current, B-type tripping characteristic, and 15kA breaking capacity, it is suitable for industrial and commercial electrical installations. This device ensures safe power distribution and equipment protection in AC systems.

## Long description

The Eaton FAZ-B25/2 is a high-performance 2-pole miniature circuit breaker engineered to provide robust overcurrent and short-circuit protection in electrical systems. Designed for demanding environments, this device ensures the safety and integrity of electrical circuits by automatically disconnecting power when faults are detected. It is built to meet rigorous industrial and commercial standards, offering reliable performance for AC power distribution networks.
Advantages
This circuit breaker stands out due to its high breaking capacity of 15kA, which allows it to handle significant fault currents safely. The B-curve tripping characteristic makes it particularly effective for protecting circuits with low inrush currents, such as resistive loads or lighting systems. Its 2-pole configuration allows for the simultaneous disconnection of both phase and neutral conductors, enhancing safety during maintenance or fault conditions. The compact design facilitates easy installation in standard distribution boards, while the durable construction ensures long-term operational reliability.
Suitable for
Industrial electrical distribution panels
Commercial building power systems
Protection of resistive loads and lighting circuits
General AC power distribution infrastructure
When it may not be suitable
This device is not intended for use in DC systems, as it is specifically rated for AC applications. Furthermore, the B-curve characteristic may not be suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a C or D curve breaker would be more appropriate to prevent nuisance tripping.
Key specifications
Number of poles: 2
Rated current: 25A
Tripping characteristic: B-curve
Breaking capacity: 15kA
System type: AC
How to use
The Eaton FAZ-B25/2 should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within an enclosure. Ensure that the supply cables are correctly sized for a 25A load and securely fastened to the terminals. Once installed, the toggle switch can be used to manually turn the circuit on or off, while the internal mechanism will automatically trip the switch to the off position in the event of an overcurrent or short-circuit.
What to consider before purchase
Verify that the 25A rating matches the requirements of your specific circuit load.
Confirm that the B-curve tripping characteristic is appropriate for the equipment being protected.
Ensure the 15kA breaking capacity meets the short-circuit current levels of your electrical installation.
Check that the 2-pole configuration is compatible with your wiring layout.
Usage recommendations
Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic testing of the installation to ensure that the protective device remains functional and that all terminal connections remain tight to prevent resistance-related issues.
