## Long description

The EATON AZ-3N-B50 is a high-performance miniature circuit breaker designed to provide reliable protection for electrical circuits in demanding environments. This 3P+N device is engineered to handle a rated current of 50A and features a B tripping characteristic, making it suitable for applications where precise overcurrent protection is required. With a robust breaking capacity of 25kA, it effectively manages high fault currents, ensuring the safety and integrity of complex electrical installations in industrial and commercial settings.
Advantages
This circuit breaker stands out due to its high breaking capacity, which allows it to safely interrupt significant fault currents that could otherwise damage sensitive equipment. The 3P+N configuration provides comprehensive protection for three-phase systems with a neutral conductor, ensuring that all lines are monitored and disconnected during a fault. Its durable construction and adherence to high engineering standards make it a dependable component for long-term electrical infrastructure stability.
Suitable for
Industrial machinery power supply protection
Commercial building electrical distribution boards
Three-phase electrical systems requiring neutral switching
Protection of cables and lines in complex installations
When it may not be suitable
This device is not intended for residential applications where a lower breaking capacity or different tripping characteristics are typically required. It is also not suitable for DC electrical systems, as it is specifically designed for AC installations.
Key specifications
Number of poles: 3P+N
Rated current: 50A
Tripping characteristic: B
Breaking capacity: 25kA
System type: AC
How to use
The EATON AZ-3N-B50 should be installed by a qualified electrician within a standard distribution board or enclosure. The device is designed for DIN-rail mounting. Ensure that the supply cables are correctly sized for a 50A load and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the toggle switch can be used to manually open or close the circuit as needed.
What to consider before purchase
Verify that the 50A rating matches your circuit requirements
Ensure the 25kA breaking capacity is appropriate for your installation's short-circuit current levels
Confirm that the B-curve characteristic is suitable for your specific load type
Check available space in your distribution board for a 3P+N device
Usage recommendations
Regularly inspect the circuit breaker for signs of wear or thermal damage. It is recommended to perform periodic testing of the switching mechanism to ensure it remains operational. If the breaker trips, investigate the cause of the fault before resetting the device.
