## Summary description

The EATON AZ-4-B25 is a high-performance 4-pole miniature circuit breaker designed for reliable electrical circuit protection. Featuring a B-tripping characteristic, a 25A rated current, and a 25kA breaking capacity, this device is suitable for industrial and commercial power distribution systems. It ensures safety by preventing overloads and short circuits in AC electrical installations.

## Long description

The EATON AZ-4-B25 is a robust 4-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in demanding environments. With a rated current of 25A and a high breaking capacity of 25kA, this device is designed to handle significant electrical loads while ensuring the integrity of your power distribution system. Its B-tripping characteristic makes it particularly effective for applications where moderate inrush currents are expected, providing a balanced approach to circuit safety and operational continuity.
Advantages
This miniature circuit breaker offers exceptional reliability and durability, meeting the rigorous standards required for industrial and commercial electrical installations. The 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral, enhancing safety during maintenance or fault conditions. Its high breaking capacity ensures that the device can safely interrupt high-energy short-circuit currents, thereby protecting downstream equipment and wiring from catastrophic damage. The compact design facilitates efficient use of space within electrical distribution boards.
Suitable for
Industrial power distribution systems
Commercial building electrical panels
Protection of lighting circuits
General AC electrical installations with moderate inrush currents
When it may not be suitable
This circuit breaker is not intended for use in DC electrical systems, as it is specifically designed for AC applications. Furthermore, it may not be the optimal choice for circuits with very high inductive loads or frequent high-current motor startups, where a C or D tripping curve would be more appropriate to prevent nuisance tripping.
Key specifications
Number of poles: 4
Rated current: 25A
Tripping characteristic: B-curve
Breaking capacity: 25kA
System compatibility: AC electrical installations
How to use
The device should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly sized for a 25A load and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the toggle switch can be used to manually open or close the circuit. In the event of an overload or short circuit, the breaker will automatically trip to the off position, requiring manual reset after the fault has been cleared.
What to consider before purchase
Verify that the 25A rating matches the requirements of your specific circuit load.
Ensure the B-curve characteristic is suitable for the connected equipment.
Confirm that the 4-pole configuration is necessary for your wiring setup.
Check 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 a functional test of the tripping mechanism periodically to ensure continued operational safety.
