## Long description

The EATON AZ-3-B20 is a high-performance 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. This device is designed to safeguard power distribution systems by effectively detecting and interrupting overloads and short circuits, thereby preventing potential damage to connected equipment and infrastructure. With its robust construction and precise engineering, it serves as a critical component for maintaining electrical safety and operational continuity in industrial and commercial settings.
Advantages
The primary advantage of this circuit breaker is its high breaking capacity of 25kA, which allows it to handle significant fault currents that standard residential breakers might not manage. The B-characteristic ensures a rapid response to short circuits while allowing for standard startup currents, making it highly efficient for general power distribution. Its 3-pole configuration provides comprehensive protection for three-phase systems, ensuring that all phases are disconnected simultaneously during a fault event. The device is built to meet rigorous international standards, offering long-term durability and consistent performance under continuous load conditions.
Suitable for
Industrial power distribution panels
Commercial building electrical systems
Three-phase motor protection
General lighting and power circuits
Infrastructure projects requiring high short-circuit protection
When it may not be suitable
This circuit breaker is not intended for use in low-current residential branch circuits where a lower amperage rating or different tripping characteristic is required. It is also not suitable for DC power systems, as it is specifically designed for AC electrical installations.
Key specifications
Number of poles: 3
Rated current: 20A
Tripping characteristic: B
Breaking capacity: 25kA
Mounting type: DIN rail
How to use
The EATON AZ-3-B20 should be installed by a qualified electrician in accordance with local electrical codes and regulations. The device is designed for standard DIN rail mounting within an electrical distribution board. Ensure that the supply voltage matches the specifications of the breaker before installation. Once mounted, connect the incoming power lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 20A rating matches your specific circuit load requirements.
Ensure the 25kA breaking capacity is appropriate for the prospective fault current at the installation point.
Confirm that the B-characteristic is suitable for your specific load type, such as resistive or low-inductive loads.
Check the available space in your distribution board for a 3-pole device.
Usage recommendations: Regularly inspect the circuit breaker for signs of thermal damage or loose connections. It is recommended to perform a periodic functional test to ensure the mechanical tripping mechanism remains operational over the lifespan of the device.
