## Long description

The EATON AZ-4-B80 is a high-performance 4-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. This device is specifically designed to safeguard industrial and commercial AC power distribution systems by effectively detecting and interrupting overloads and short circuits. With its robust construction and precise engineering, it ensures consistent operational stability and enhances the overall safety of electrical installations.
Advantages
This circuit breaker offers exceptional reliability due to its high breaking capacity of 25kA, which allows it to handle significant fault currents without compromising performance. The B-characteristic curve provides an optimal balance between sensitivity and operational continuity, making it suitable for a wide range of applications where rapid disconnection is required during a fault. Its 4-pole configuration allows for the simultaneous protection of three-phase systems with a neutral conductor, ensuring comprehensive coverage and simplified installation in complex electrical panels.
Suitable for
Industrial power distribution boards
Commercial building electrical systems
Protection of three-phase circuits with neutral
Heavy-duty electrical infrastructure
This device may not be suitable for residential applications where lower current ratings are typically required or where the physical dimensions of the 4-pole unit exceed the available space in standard consumer units. It is also not intended for DC power systems, as it is specifically designed for AC distribution networks.
Key specifications
Number of poles: 4
Rated current: 80A
Tripping characteristic: B
Breaking capacity: 25kA
Application: AC power systems
The device should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on standard DIN rails within an appropriate distribution enclosure. Ensure that the supply voltage and frequency match the device ratings before connection. Once installed, the breaker can be manually switched to control the circuit, and it will automatically trip to the off position in the event of an electrical fault.
What to consider before purchase
Verify that the 80A rated current matches your circuit requirements
Ensure there is sufficient space in the distribution board for a 4-pole device
Confirm that the installation environment is compatible with AC circuit protection equipment
Check that the breaking capacity meets the prospective short-circuit current of your system
Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic testing of the switching mechanism to ensure it remains in good working order. Do not attempt to repair or modify the internal components of the device.
