## Long description

The EATON AZ-3N-B20 is a robust miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. This 3P+N device is designed for AC systems, offering a rated current of 20A and a high breaking capacity of 25kA. It serves as a critical component in power distribution networks, ensuring that electrical installations remain safe from the risks associated with overloads and short circuits.
Advantages
This circuit breaker stands out due to its high breaking capacity, which allows it to handle significant fault currents without compromising the integrity of the electrical system. The B-curve tripping characteristic ensures precise and rapid response to overcurrent conditions, providing an optimal balance between operational continuity and safety. Its 3P+N configuration makes it highly versatile for three-phase systems requiring neutral switching, while the durable construction ensures long-term reliability in both industrial and commercial applications.
Suitable for
Industrial power distribution panels
Commercial building electrical systems
Protection of lighting and heating circuits
Three-phase electrical installations requiring neutral disconnection
This device may not be suitable for DC electrical systems, as it is specifically designed for AC operation. Additionally, it should not be used in applications where the required rated current exceeds 20A or where the environmental conditions fall outside the manufacturer's specified operating temperature and humidity ranges.
Key specifications
Rated current: 20A
Number of poles: 3P+N
Tripping characteristic: B-curve
Breaking capacity: 25kA
Operating voltage type: AC
Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is typically mounted on a standard DIN rail within a distribution board. Ensure that all wire connections are tightened to the specified torque settings to prevent overheating and ensure a secure electrical contact before energizing the circuit.
What to consider before purchase
Verify that the 20A rating matches your circuit load requirements
Ensure the 3P+N configuration is compatible with your distribution system
Check that the B-curve characteristic is appropriate for your specific load type
Confirm that the 25kA breaking capacity meets the short-circuit current requirements of your installation
Always inspect the device for any signs of physical damage before installation and ensure that the power supply is completely disconnected during the mounting process to prevent electrical shock.
