## Summary description

The Eaton FAZ-Z3/3 is a high-performance 3-pole miniature circuit breaker designed for reliable overcurrent and short-circuit protection. With a 3A rated current and 15kA breaking capacity, it features Z-type tripping characteristics suitable for sensitive electronic equipment. This industrial-grade device ensures electrical safety in distribution systems and is built for demanding applications requiring precise protection.

## Long description

The Eaton FAZ-Z3/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection against overcurrent and short-circuit events in electrical distribution systems. This device is specifically designed to handle a rated current of 3A and offers a high breaking capacity of 15kA, ensuring reliable performance in demanding industrial and commercial environments. By utilizing Z-type tripping characteristics, this circuit breaker is optimized for applications where precise and rapid response to fault currents is required to safeguard sensitive electronic components.
Advantages
The primary advantage of this Eaton miniature circuit breaker lies in its specialized Z-characteristic, which provides a tighter tripping range compared to standard curves, making it ideal for protecting sophisticated electronic equipment from transient surges. Its 3-pole configuration allows for the simultaneous disconnection of three phases, enhancing safety in three-phase power distribution networks. The high 15kA breaking capacity ensures that the device can safely interrupt significant fault currents, preventing damage to downstream infrastructure and minimizing downtime during electrical failures.
Suitable for
Protection of sensitive electronic control circuits
Industrial automation and PLC systems
Three-phase power distribution boards
Medical or laboratory equipment requiring precise overcurrent protection
When it may not be suitable
This circuit breaker is not intended for general-purpose residential lighting or standard power outlet circuits, as the Z-characteristic is specifically tuned for sensitive electronics and may cause nuisance tripping in circuits with high inrush currents, such as those powering large motors or transformers.
Key specifications
Number of poles: 3
Rated current: 3A
Breaking capacity: 15kA
Tripping characteristic: Z
Mounting type: DIN rail
How to use
The device is designed for installation onto a standard 35mm DIN rail within an electrical distribution enclosure. Ensure that the power supply is disconnected before mounting. Secure the breaker firmly onto the rail and connect the incoming supply lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque settings. Once installed, the toggle switch can be used to manually energize or de-energize the circuit.
What to consider before purchase
Verify that the Z-characteristic is appropriate for your specific load type
Ensure the 3A rated current matches the circuit requirements
Confirm that the 15kA breaking capacity meets the short-circuit current rating of your installation
Check available space on the DIN rail within your distribution board
Usage recommendations: Periodic inspection of the terminal connections is recommended to ensure they remain tight and free from oxidation. If the breaker trips, investigate the cause of the fault before resetting the device to prevent potential damage to the connected equipment.
