## Long description

The EATON AZ-4-B20 is a high-performance 4-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. This industrial-grade device is designed to safeguard AC systems by effectively interrupting current flow during overloads or short circuits, ensuring the integrity of connected equipment and the safety of the electrical infrastructure.
Advantages
This circuit breaker stands out due to its high breaking capacity of 25kA, which allows it to handle significant fault currents that standard residential breakers might not manage. The 4-pole configuration provides comprehensive protection for three-phase systems with a neutral conductor, ensuring all lines are disconnected simultaneously during a fault. Its B-characteristic makes it particularly suitable for applications where moderate inrush currents are expected, providing a balanced response time that prevents nuisance tripping while maintaining high safety standards.
Suitable for
Industrial power distribution boards
Three-phase motor protection
Commercial building electrical systems
Heavy-duty machinery power supply
Infrastructure and utility installations
When it may not be suitable
This device is not intended for use in low-current residential lighting circuits where a lower amperage rating would be more appropriate. Additionally, it is not designed for DC electrical systems, as it is specifically calibrated for AC applications.
Key specifications
Number of poles: 4
Rated current: 20A
Tripping characteristic: B
Breaking capacity: 25kA
System type: AC
How to use
The EATON AZ-4-B20 must be installed by a qualified electrician in accordance with local electrical codes. 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 20A load and securely fastened to the terminals to prevent overheating. Once installed, the toggle switch can be used to manually disconnect or reconnect the circuit as needed.
What to consider before purchase
Verify that the 20A rating matches the requirements of your specific circuit load.
Ensure the 4-pole configuration is compatible with your existing wiring setup.
Confirm that the 25kA breaking capacity meets the short-circuit current rating of your electrical installation.
Check the available space in your distribution board for a 4-module wide device.
Usage recommendations
Regularly inspect the circuit breaker for signs of thermal damage or loose connections. It is recommended to perform periodic testing of the switching mechanism to ensure it remains operational and free from debris or environmental contaminants.
