## Long description

The Eaton FAZ-Z4/3 is a high-performance 3-pole miniature circuit breaker engineered to provide robust electrical protection in demanding environments. With a Z-type tripping characteristic and a 4A rated current, this device is specifically designed to safeguard sensitive electronic components and control circuits from the risks of short circuits and overloads. Its 15kA breaking capacity ensures reliable performance in industrial and commercial electrical distribution systems.
Advantages
This miniature circuit breaker offers exceptional precision in fault detection, particularly for circuits with low-energy electronic loads. The Z-characteristic provides a fast response time to short-circuit currents, minimizing the risk of damage to delicate equipment. Its 3-pole configuration allows for the simultaneous disconnection of all phases, enhancing safety during maintenance or fault conditions. The compact design facilitates efficient installation in standard distribution boards, while the high breaking capacity provides peace of mind in installations where high fault currents may occur.
Suitable for
Protection of sensitive electronic equipment
Control circuits in industrial automation
Semiconductor and PLC-based systems
Commercial electrical distribution panels
This circuit breaker may not be suitable for general-purpose lighting or standard power outlet circuits, as the Z-characteristic is specifically tuned for low-current electronic applications. Using this device in circuits with high inrush currents, such as those powering large motors or transformers, may lead to nuisance tripping.
Key specifications
Number of poles: 3
Rated current: 4A
Tripping characteristic: Z
Breaking capacity: 15kA
Mounting type: DIN rail
The device is designed for installation on a standard DIN rail within an electrical enclosure. Ensure that the power supply is disconnected before mounting or removing the breaker. The cables should be securely fastened to the terminals, ensuring proper torque is applied according to the manufacturer's guidelines to prevent overheating or loose connections.
What to consider before purchase
Verify that the Z-characteristic matches the requirements of your specific load
Ensure the 4A rating is appropriate for the connected equipment
Check that the 15kA breaking capacity meets the short-circuit current rating of your installation
Confirm space availability on the DIN rail
For optimal performance and safety, always ensure that the circuit breaker is installed by a qualified electrician in accordance with local electrical codes and regulations. Periodically inspect the terminals for tightness to maintain reliable electrical contact.
