This device is ideal for industrial and commercial electrical installations, ensuring safety against overloads and short circuits in AC systems.

## Long description

The Eaton FAZ-B15/3 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This device is designed to detect and interrupt overcurrents, including both overloads and short circuits, ensuring the integrity of your electrical infrastructure. With its B-curve tripping characteristic and a 15A rated current, it offers precise response times for standard applications, while its 15kA breaking capacity provides significant safety margins for industrial and commercial power distribution systems.
Advantages
This miniature circuit breaker stands out due to its high breaking capacity, which allows it to handle substantial fault currents safely. The 3-pole configuration makes it suitable for three-phase power systems, providing simultaneous disconnection of all phases during a fault. Its compact design facilitates efficient use of space within distribution boards, and the reliable B-curve characteristic ensures that the device trips quickly under short-circuit conditions while remaining stable during minor, temporary inrush currents. The build quality reflects Eaton's commitment to durability and long-term operational reliability in professional electrical installations.
Suitable for
Three-phase industrial power distribution systems
Commercial building electrical panels
Protection of lighting and control circuits
General electrical infrastructure requiring 15A protection
When it may not be suitable
This circuit breaker is not intended for use in DC systems, as it is specifically designed for AC applications. Furthermore, it may not be appropriate for circuits with high-starting-current equipment, such as large motors or heavy-duty transformers, where a C or D curve characteristic would be required to prevent nuisance tripping.
Key specifications
Number of poles: 3
Rated current: 15A
Tripping characteristic: B-curve
Breaking capacity: 15kA
System compatibility: AC
How to use
The device is designed for mounting onto a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Ensure that the supply cables are properly sized for a 15A load and securely fastened to the terminals. Once installed, the toggle switch allows for manual switching of the circuit, and the clear indicator provides visual confirmation of the contact position.
What to consider before purchase
Verify that the 15A rating matches the requirements of your specific circuit load.
Ensure the B-curve characteristic is appropriate for the connected equipment.
Confirm that the 15kA breaking capacity meets the short-circuit current rating of your installation site.
Check that the 3-pole configuration is compatible with your three-phase power supply.
Usage recommendations
Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic testing of the switching mechanism to ensure continued operational readiness. If the breaker trips, investigate the cause of the fault before attempting to reset the device.
