## Long description

The EATON AZ-3-B50 is a high-performance 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. This device is designed to safeguard power distribution systems by effectively interrupting current flow during overloads or short circuits, thereby preventing potential damage to equipment and infrastructure. With its robust construction and high breaking capacity, it serves as a critical component in maintaining electrical safety and operational continuity.
Advantages
This circuit breaker offers exceptional reliability due to its high breaking capacity of 25kA, which allows it to handle significant fault currents safely. The B-characteristic ensures a precise tripping response, making it suitable for applications where protection against short circuits and overloads is essential. Its 3-pole design provides comprehensive coverage for three-phase electrical systems, ensuring that all phases are disconnected simultaneously during a fault event. The durable build quality ensures long-term performance even in intensive industrial or commercial settings.
Suitable for
Industrial power distribution panels
Commercial building electrical systems
Protection of three-phase electrical circuits
Heavy-duty electrical installations
When it may not be suitable
This device is not intended for use in single-phase residential circuits where a 1-pole or 2-pole breaker would be sufficient. It is also not suitable for applications requiring different tripping characteristics, such as C or D curves, which are designed for circuits with high inrush currents.
Key specifications
Number of poles: 3
Rated current: 50A
Tripping characteristic: B
Breaking capacity: 25kA
System type: AC
How to use
The EATON AZ-3-B50 should be installed by a qualified electrician within a standard distribution board or enclosure. It is designed for mounting on a standard DIN rail. Ensure that the supply voltage and load requirements are compatible with the device specifications before installation. Once mounted, connect the incoming power lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque settings.
What to consider before purchase
Verify that the 50A rated current matches your circuit load requirements.
Ensure the 3-pole configuration is appropriate for your specific electrical system.
Check that the available space in your distribution board accommodates a 3-pole device.
Confirm that the B-characteristic is suitable for the connected equipment.
Usage recommendations: Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform periodic testing of the tripping mechanism to ensure the device remains fully operational and provides the intended level of protection.
