Product information

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

Usage recommendations

Regularly inspect the circuit breaker for signs of wear or thermal damage. Test the device periodically to ensure the mechanical tripping mechanism remains functional and that the electrical connections remain tight.
