## Summary description

The EATON AZ-3-D50 is a high-performance 3-pole miniature circuit breaker designed for reliable electrical circuit protection. Featuring a D-type tripping characteristic, a 50A rated current, and a 25kA breaking capacity, it is ideal for industrial and commercial applications with high inrush currents. This device ensures safety by preventing overloads and short circuits in AC electrical distribution systems.

## Long description

The EATON AZ-3-D50 is a robust 3-pole miniature circuit breaker engineered to provide dependable protection for electrical distribution systems. Designed for demanding environments, this device effectively safeguards circuits against overloads and short circuits, ensuring the integrity of your electrical infrastructure. With its high breaking capacity and specialized tripping characteristics, it serves as a critical component in maintaining operational safety in professional settings.
Advantages
This circuit breaker stands out due to its high 25kA breaking capacity, which allows it to handle significant fault currents without compromising performance. The D-type tripping curve is specifically optimized for applications involving equipment with high inrush currents, such as large motors or transformers, preventing nuisance tripping during startup. Its 3-pole configuration makes it perfectly suited for three-phase AC systems, providing comprehensive protection across all phases simultaneously.
Suitable for
Industrial machinery and motor control centers
Commercial electrical distribution boards
Systems with high inductive loads
Applications requiring protection against high inrush currents
When it may not be suitable
This device is not intended for residential applications where standard B or C curve breakers are typically sufficient. Using a D-curve breaker in circuits without high inrush currents may result in delayed protection during minor faults.
Key specifications
Number of poles: 3
Rated current: 50A
Tripping characteristic: D-curve
Breaking capacity: 25kA
System type: AC
How to use
The EATON AZ-3-D50 should be installed by a qualified electrician into a standard DIN rail distribution board. Ensure that the supply voltage and load requirements are compatible with the device specifications before installation. Once mounted, connect the three-phase input and output cables securely to the corresponding terminals, ensuring all connections are tightened to the manufacturer's torque requirements to prevent overheating.
What to consider before purchase
Verify that the 50A rating matches your circuit load requirements
Ensure the D-curve characteristic is appropriate for your specific load type
Confirm that the 25kA breaking capacity meets the short-circuit current rating of your installation
Check available space in your distribution panel for a 3-pole device
Usage recommendations
Regularly inspect the circuit breaker for signs of thermal stress or loose connections. It is recommended to perform periodic testing of the tripping mechanism to ensure continued reliability in industrial environments.
