## Long description

The EATON AZ-4-B50 is a robust 4-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in demanding environments. With a rated current of 50A and a high breaking capacity of 25kA, this device is specifically designed to safeguard industrial and commercial power distribution systems against the risks of overloads and short circuits. Its B-curve tripping characteristic ensures precise response times, making it an essential component for maintaining the integrity and safety of AC electrical installations.
Advantages
This miniature circuit breaker offers exceptional reliability and durability, meeting the rigorous standards required for professional electrical infrastructure. The 4-pole configuration allows for comprehensive control and protection across three-phase systems with a neutral conductor. Its high breaking capacity of 25kA provides a significant safety margin, effectively handling high fault currents that might occur in industrial settings. The B-curve design is optimized for general applications, ensuring that the circuit is interrupted promptly during fault conditions while minimizing nuisance tripping.
Suitable for
Industrial power distribution boards
Commercial building electrical systems
Three-phase AC installations requiring neutral switching
Protection of cables and lines in high-load environments
This device may not be suitable for residential applications where lower breaking capacities are sufficient and the physical size of a 4-pole breaker might be excessive for standard consumer units. It is also not intended for DC electrical systems, as it is specifically designed for AC installations.
Key specifications
Number of poles: 4
Rated current: 50A
Tripping characteristic: B-curve
Breaking capacity: 25kA
Application type: AC electrical systems
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for mounting on a standard DIN rail within an appropriate distribution enclosure. Ensure that the supply voltage and frequency match the device ratings before connection. Securely terminate all conductors to the designated terminals, ensuring proper torque settings to prevent overheating.
What to consider before purchase
Verify that the 4-pole configuration matches your specific circuit requirements
Ensure the 50A rating is appropriate for the connected load
Check the available space in your distribution board for a 4-pole device
Confirm that the installation environment is compatible with AC-rated equipment
