## Summary description

The EATON AZ-3N-D20 is a high-performance 3P+N miniature circuit breaker designed for industrial and commercial electrical installations. It features a 20A rated current, D-type tripping characteristic, and a 25kA breaking capacity for AC systems. This device provides reliable protection against short circuits and overloads, ensuring safety and operational stability in demanding electrical distribution networks.

## Long description

The EATON AZ-3N-D20 is a robust miniature circuit breaker engineered for demanding industrial and commercial electrical environments. This 3P+N device is designed to provide comprehensive protection for electrical distribution networks by effectively managing overloads and short circuits. With a rated current of 20A and a high breaking capacity of 25kA, it ensures consistent performance and safety in systems where high-inrush currents are common.
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 D-type tripping characteristic makes it particularly suitable for circuits with high inductive loads, preventing nuisance tripping during motor startups or transformer energization. Its 3P+N configuration provides versatile installation options for three-phase systems requiring neutral switching, while the EATON build quality ensures long-term operational reliability and durability in professional settings.
Suitable for
Industrial machinery and motor control circuits
Commercial electrical distribution boards
Systems with high-inrush current equipment
Three-phase power distribution with neutral disconnection
When it may not be suitable
This device is not intended for residential applications where standard B or C curve breakers are typically sufficient for lighting and general-purpose outlets. Using a D-curve breaker in circuits without high-inrush loads may result in delayed protection during minor faults.
Key specifications
Rated current: 20A
Tripping characteristic: D-curve
Poles: 3P+N
Breaking capacity: 25kA
System type: AC
How to use
The EATON AZ-3N-D20 should be installed by a qualified electrician within a standard distribution board or enclosure. The device is designed for DIN-rail mounting. Ensure that the supply cables are correctly sized for a 20A load and that all terminal connections are tightened to the manufacturer's specified torque settings to prevent overheating. Once installed, the toggle switch allows for manual operation to isolate the circuit when necessary.
What to consider before purchase
Verify that the D-curve characteristic matches your load requirements
Ensure the 25kA breaking capacity is appropriate for your installation's prospective short-circuit current
Confirm space availability on the DIN rail for a 3P+N device
Usage recommendations
Regularly inspect the circuit breaker for signs of thermal stress or physical damage. It is recommended to perform periodic testing of the switching mechanism to ensure it remains functional over the lifespan of the installation.
