## Summary description

The EATON AZ-2-B40 is a high-performance 2-pole miniature circuit breaker designed for reliable electrical circuit protection. Featuring a 40A rated current, B-type tripping characteristic, and a 25kA breaking capacity, this device ensures safety in industrial and commercial electrical installations by preventing overloads and short circuits.

## Long description

The EATON AZ-2-B40 is a robust 2-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in demanding environments. With a rated current of 40A and a high breaking capacity of 25kA, this device is specifically designed to safeguard industrial and commercial electrical systems against the risks of overloads and short circuits, ensuring operational continuity and safety.
Advantages
This circuit breaker offers exceptional reliability through its high-performance construction, which is built to withstand rigorous electrical conditions. The B-curve tripping characteristic provides a precise response to overcurrent situations, making it an ideal choice for protecting sensitive equipment and standard electrical wiring. Its 2-pole design allows for the simultaneous disconnection of both phase and neutral or two phases, enhancing safety during maintenance and fault conditions.
Suitable for
Industrial electrical distribution systems
Commercial building power management
Protection of lighting and heating circuits
General electrical infrastructure requiring high breaking capacity
When it may not be suitable
This device is not intended for residential applications where a lower breaking capacity is typically sufficient and cost-effective. It is also not suitable for circuits requiring C or D tripping curves, which are designed for high-inrush current loads like large motors or transformers.
Key specifications
Number of poles: 2
Rated current: 40A
Tripping characteristic: B-curve
Breaking capacity: 25kA
Mounting type: DIN rail
How to use
The device should be installed by a qualified electrician onto a standard DIN rail within a distribution board or enclosure. Ensure that the supply cables are securely connected to the terminals, observing the correct torque settings to prevent overheating. Once installed, the breaker can be manually toggled to the ON position to energize the circuit. In the event of a fault, the breaker will trip automatically to the OFF position, requiring manual reset after the underlying issue has been resolved.
What to consider before purchase
Verify that the 40A rating matches your circuit load requirements
Ensure the 25kA breaking capacity is appropriate for your installation's prospective short-circuit current
Confirm that the B-curve characteristic is compatible with your connected equipment
Check available space in your distribution board for a 2-pole module
Usage recommendations
Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform periodic testing of the tripping mechanism to ensure the device remains functional and ready to protect your electrical system.
