## Long description

The EATON AZ-3-C40 is a robust 3-pole miniature circuit breaker engineered to provide superior protection for electrical distribution systems. Designed for demanding environments, this device effectively monitors current flow and automatically disconnects the circuit in the event of an overload or short circuit, thereby preventing damage to connected equipment and infrastructure. With its high breaking capacity and precise C-characteristic, it serves as a reliable component in professional electrical setups.
Advantages
This circuit breaker stands out due to its high breaking capacity of 25kA, which allows it to handle significant fault currents safely. The 3-pole configuration makes it perfectly suited for three-phase power systems, ensuring balanced protection across all phases. Its C-characteristic is specifically optimized for applications with moderate inrush currents, providing a balance between sensitivity and operational stability. The durable construction ensures long-term reliability even in intensive industrial or commercial use cases.
Suitable for
Industrial power distribution boards
Commercial building electrical installations
Protection of three-phase motors and equipment
Heavy-duty electrical circuits requiring high fault current handling
When it may not be suitable
This device is not intended for residential applications where lower breaking capacities are sufficient and more cost-effective solutions are available. It is also not suitable for circuits requiring B-characteristic breakers, which are designed for different inrush current profiles.
Key specifications
Number of poles: 3
Rated current: 40A
Tripping characteristic: C
Breaking capacity: 25kA
Mounting type: DIN rail
How to use
The EATON AZ-3-C40 should be installed by a qualified electrician in accordance with local electrical codes. It is designed for mounting onto a standard DIN rail within a distribution cabinet. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, maintaining the correct torque settings as specified by the manufacturer. Once installed, the toggle switch allows for manual operation to connect or disconnect the circuit as needed.
What to consider before purchase
Verify that the 40A rated current matches the requirements of your circuit load.
Ensure the 25kA breaking capacity is appropriate for the prospective fault current at the installation point.
Confirm that the 3-pole configuration is compatible with your three-phase power supply.
Check the available space in your distribution board for a 3-module wide device.
Usage recommendations
Regularly inspect the circuit breaker for signs of wear or thermal damage and perform periodic testing of the switching mechanism to ensure continued operational safety.
