## Long description

The EATON AZ-2-B125 is a robust 2-pole miniature circuit breaker engineered to provide dependable overcurrent protection in demanding electrical environments. With a rated current of 125A and a high breaking capacity of 15kA, this device is built to handle significant electrical loads while maintaining system integrity. Its B-curve tripping characteristic makes it particularly effective for applications where rapid response to short circuits is required, ensuring that connected equipment and wiring remain protected against potential faults.
Advantages
This circuit breaker stands out due to its high-performance construction and reliability in industrial and commercial power distribution systems. The 2-pole design allows for simultaneous disconnection of both phases, enhancing safety during maintenance or fault conditions. Its 15kA breaking capacity provides a substantial safety margin, allowing the device to interrupt high fault currents effectively. The B-curve characteristic is optimized for general-purpose applications, offering a balance between sensitivity and operational stability.
Suitable for
Industrial power distribution panels
Commercial building electrical systems
Protection of lighting and heating circuits
General electrical infrastructure requiring 125A capacity
This circuit breaker may not be suitable for applications requiring a different tripping characteristic, such as C or D curves, which are typically used for high-inrush current loads like large motors or transformers. It is also not intended for DC electrical systems, as it is specifically designed for AC operation.
Key specifications
Number of poles: 2
Rated current: 125A
Tripping characteristic: B-curve
Breaking capacity: 15kA
Operating voltage: AC
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within an enclosure. Ensure that the supply voltage and frequency match the specifications of the breaker before connection. Tighten all terminal connections to the manufacturer-specified torque to prevent overheating and ensure a secure electrical contact.
What to consider before purchase
Verify that the 125A rating matches your circuit load requirements
Ensure the 15kA breaking capacity is sufficient for your installation's prospective short-circuit current
Confirm compatibility with your existing distribution board or DIN rail system
Check that the B-curve characteristic is appropriate for the connected load types
For optimal performance and safety, regularly inspect the circuit breaker for signs of wear or heat damage and ensure that the surrounding environment remains within the specified operating temperature range.
