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

## Long description

The EATON FAZ-B3/1 is a high-performance 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in various environments. This device is designed to detect and interrupt overcurrent conditions, specifically overloads and short circuits, to prevent damage to wiring and connected equipment. With its compact modular design, it integrates seamlessly into standard distribution boards and electrical panels, offering a reliable solution for maintaining system integrity in both commercial and industrial settings.
Advantages
This circuit breaker stands out due to its high breaking capacity of 15kA, which allows it to handle significant fault currents safely. The B-curve tripping characteristic ensures rapid response to short circuits while allowing for standard operational surges, making it highly effective for protecting sensitive electronic equipment and lighting circuits. Its durable construction and precision engineering from EATON guarantee long-term operational reliability and consistent performance under demanding electrical conditions.
Suitable for
Commercial electrical distribution systems
Industrial control panels
Protection of lighting circuits
Sensitive electronic equipment installations
Residential sub-distribution boards
When it may not be suitable
This device is specifically designed for AC systems and should not be used in DC applications unless explicitly rated for such use. Additionally, the 3A rated current is intended for low-power circuits, so it is not appropriate for high-load applications such as heavy machinery or large heating elements that require higher amperage ratings.
Key specifications
Number of poles: 1
Tripping characteristic: B-curve
Rated current: 3A
Breaking capacity: 15kA
System compatibility: AC
How to use
The EATON FAZ-B3/1 is designed for mounting on a standard DIN rail. Installation should be performed by a qualified electrician in accordance with local electrical codes. The device features secure terminal connections for reliable wiring. Once mounted, the toggle switch allows for manual switching of the circuit, while the internal mechanism automatically trips the breaker to the off position in the event of an electrical fault.
What to consider before purchase
Verify that the 3A rated current matches the requirements of your specific circuit.
Ensure the 15kA breaking capacity is sufficient for the prospective fault current at the installation point.
Confirm that the B-curve characteristic is appropriate for the type of load being protected.
Check available space in your distribution board for a 1-pole modular device.
Usage recommendations: Always ensure that the power supply is disconnected before attempting installation or maintenance. Regularly inspect the breaker for signs of wear or damage and test the functionality periodically to ensure continued protection.
