## Summary description

The EATON AZ-4-D50 is a high-performance 4-pole miniature circuit breaker designed for industrial and commercial electrical distribution systems. Featuring a 50A rated current, D-type tripping characteristic, and a 25kA breaking capacity, this device provides reliable protection against short circuits and overloads. It is engineered for AC applications, ensuring safety and operational stability in demanding electrical installations.

## Long description

The EATON AZ-4-D50 is a robust 4-pole miniature circuit breaker engineered for high-performance electrical distribution in industrial and commercial environments. This device is specifically designed to manage electrical loads of 50A and features a D-type tripping characteristic, making it ideal for circuits with high inrush currents. With a substantial breaking capacity of 25kA, it ensures reliable protection against short circuits and overloads, maintaining the integrity and safety of complex electrical systems.
Advantages
This circuit breaker offers exceptional durability and operational reliability in demanding settings. Its 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral, providing comprehensive protection for three-phase systems. The D-curve tripping characteristic is specifically optimized for applications involving motors, transformers, and other inductive loads that generate significant current spikes during startup. The high breaking capacity ensures that the device can safely interrupt high fault currents, preventing damage to downstream equipment and infrastructure.
Suitable for
Industrial machinery and motor control centers
Commercial electrical distribution boards
Systems with high inductive loads
Three-phase power distribution networks
When it may not be suitable
This circuit breaker is not intended for residential applications where lower breaking capacities are sufficient and where the D-curve tripping characteristic might be unnecessary. It is also not suitable for DC electrical systems, as it is specifically engineered for AC applications.
Key specifications
Rated current: 50A
Number of poles: 4
Tripping characteristic: D-curve
Breaking capacity: 25kA
Application type: AC
How to use
The EATON AZ-4-D50 should be installed by a qualified electrician in accordance with local electrical codes and safety standards. It is designed for mounting on a standard DIN rail within an electrical distribution enclosure. Ensure that the supply cables are correctly sized for a 50A load and securely fastened to the terminals to prevent overheating. Once installed, the device can be manually switched on or off using the front-facing toggle, and it will automatically trip in the event of an electrical fault.
What to consider before purchase
Verify that the 50A rating matches your circuit requirements
Ensure the D-curve characteristic is appropriate for your specific load type
Confirm that your distribution board has sufficient space for a 4-pole device
Check that the 25kA breaking capacity meets the fault current levels of your installation
Usage recommendations
Regular inspection of the terminal connections and the physical condition of the circuit breaker is recommended to ensure long-term operational safety. Do not attempt to bypass or modify the tripping mechanism.
