## Summary description

The Eaton FAZ-S4/1 is a high-performance miniature circuit breaker designed for reliable electrical circuit protection. Featuring a 4A rated current and 15kA breaking capacity, this 1-pole device with S-type tripping characteristic ensures safety in industrial and commercial electrical installations. It provides effective protection against short circuits and overloads, maintaining system integrity and operational efficiency.

## Long description

The Eaton FAZ-S4/1 is a professional-grade miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. With a rated current of 4A and a high breaking capacity of 15kA, this single-pole device is specifically designed to handle the rigorous requirements of industrial and commercial power distribution systems. Its S-type tripping characteristic offers a specialized response profile, ensuring that the circuit breaker reacts precisely to overloads and short circuits while maintaining the overall stability of the electrical infrastructure.
Advantages
This circuit breaker stands out due to its high breaking capacity, which allows it to safely interrupt significant fault currents, thereby protecting sensitive equipment and preventing damage to the electrical installation. The S-type characteristic provides a balanced tripping behavior that is particularly effective for circuits where specific selectivity or protection against particular types of surges is required. Its compact single-pole design facilitates efficient use of space within distribution boards, while the high-quality construction ensures long-term reliability and consistent performance under continuous operational loads.
Suitable for
Industrial control panels and automation systems
Commercial building electrical distribution boards
Protection of sensitive electronic equipment
Circuits requiring specific selectivity in fault conditions
When it may not be suitable
This device is not intended for residential applications where standard B or C curve characteristics are typically required for general household appliances. It may also be unsuitable for circuits with high inrush currents that could cause nuisance tripping due to the specific S-type characteristic.
Key specifications
Rated current: 4A
Number of poles: 1
Breaking capacity: 15kA
Tripping characteristic: S-type
How to use
The Eaton FAZ-S4/1 is designed for installation on a standard DIN rail within a distribution enclosure. It should be mounted by a qualified electrician in accordance with local electrical regulations. The device features terminal connections that accept standard wiring, ensuring a secure and reliable electrical contact. Once installed, the toggle switch allows for manual operation to disconnect or reconnect the circuit as needed, while the internal mechanism automatically trips the switch to the off position in the event of a detected fault.
What to consider before purchase
Verify that the 4A current rating matches the load requirements of your specific circuit.
Ensure the S-type tripping characteristic is compatible with the connected equipment.
Check that the 15kA breaking capacity meets the short-circuit current levels of your installation site.
Confirm that the single-pole configuration is appropriate for your wiring system.
Usage recommendations
Always ensure that the circuit breaker is installed in a clean, dry environment and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating. Regular inspection of the device is recommended to ensure continued operational safety.
