Eaton FAZ-Z1/3 Miniature Circuit Breaker, 3-Pole, 1A, 10kA

The Eaton FAZ-Z1/3 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for precision and reliability, this device is essential for safeguarding sensitive equipment against the risks of overloads and short circuits in demanding industrial and commercial environments. With its compact design and high breaking capacity, it ensures consistent performance and enhanced safety for complex electrical distribution systems.

Advantages

This miniature circuit breaker offers exceptional operational reliability due to its specialized Z-characteristic, which is specifically calibrated for sensitive applications. The 3-pole configuration allows for the simultaneous disconnection of all phases, ensuring comprehensive protection. Its high breaking capacity of 10kA provides the necessary resilience to handle significant fault currents, thereby preventing damage to connected infrastructure and minimizing downtime in critical electrical installations.

Suitable for

• Industrial control panels and automation systems
• Protection of sensitive electronic equipment
• Commercial electrical distribution boards
• Applications requiring precise overcurrent protection

When it may not be suitable

This circuit breaker is not intended for high-current applications that exceed its 1A rating, as it will trigger prematurely. It is also not suitable for residential circuits that require standard B or C characteristic breakers for general lighting and power outlets.

Key specifications

• Rated current: 1A
• Number of poles: 3
• Breaking capacity: 10kA
• Tripping characteristic: Z

How to use

The device is designed for standard DIN-rail mounting within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply cables are securely fastened to the terminals and that the torque specifications are followed to prevent loose connections. Once installed, the toggle switch can be used to manually engage or disengage the circuit.

What to consider before purchase

• Verify that the 1A rated current is appropriate for your specific load requirements.
• Ensure the Z-characteristic matches the sensitivity needs of your connected equipment.
• Confirm that the 3-pole configuration is compatible with your electrical system layout.

Usage recommendations

Regularly inspect the circuit breaker for signs of wear or thermal damage. It is recommended to perform periodic functional checks to ensure the tripping mechanism remains responsive and that all terminal connections remain tight over time.
