## Long description

The Eaton FAZ-B50/3 is a robust 3-pole miniature circuit breaker engineered to provide dependable protection against overcurrents and short circuits in electrical distribution systems. With a rated current of 50A and a B-curve tripping characteristic, this device is specifically designed to handle the demands of commercial and industrial environments, ensuring that connected circuits remain protected while maintaining operational continuity.
Advantages
This circuit breaker offers exceptional reliability through its high breaking capacity of 15kA, which allows it to safely interrupt significant fault currents. The 3-pole configuration makes it suitable for three-phase power distribution, providing comprehensive coverage for complex electrical setups. Its design focuses on durability and precision, minimizing the risk of nuisance tripping while ensuring rapid response during genuine electrical faults, which helps in safeguarding sensitive equipment and infrastructure.
Suitable for
Commercial electrical distribution boards
Industrial machinery power supply circuits
Three-phase electrical installations
Protection of lighting and heating systems
When it may not be suitable
This device is not intended for residential applications where a lower breaking capacity or different tripping characteristics might be required. It is also not suitable for DC circuits unless specifically rated for such use, as the B-curve is optimized for specific AC load profiles.
Key specifications
Number of poles: 3
Rated current: 50A
Tripping characteristic: B-curve
Breaking capacity: 15kA
Mounting type: DIN rail
How to use
The Eaton FAZ-B50/3 is designed for installation on a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply cables are properly sized for a 50A load and securely fastened to the terminals to prevent overheating. Once installed, the toggle switch can be used to manually isolate the circuit for maintenance or to reset the breaker after a trip event.
What to consider before purchase
Verify that the 50A rating matches your circuit load requirements
Ensure the 15kA breaking capacity meets the short-circuit current levels of your installation
Confirm that the B-curve tripping characteristic is appropriate for your specific load type
Check available space in your distribution board for a 3-pole device
Usage recommendations
Regular inspection of the terminal connections and the physical condition of the breaker is recommended to ensure long-term performance. If the breaker trips, investigate the cause of the fault before attempting to reset the device.
