Eaton FAZ-Z0,5/3 Miniature Circuit Breaker, 3-Pole, Z-Characteristic, 0.5A, 15kA

The Eaton FAZ-Z0,5/3 is a high-performance 3-pole miniature circuit breaker engineered to provide precise overcurrent and short-circuit protection in demanding electrical environments. With a rated current of 0.5A and a specialized Z-type tripping characteristic, this device is specifically designed to safeguard sensitive electronic components and complex control circuits where rapid response to fault currents is essential. Its robust construction and 15kA breaking capacity make it a reliable choice for maintaining operational continuity and safety in industrial and commercial power distribution systems.

Advantages

This miniature circuit breaker offers exceptional reliability due to its advanced Z-characteristic, which allows for a very low threshold for short-circuit tripping, effectively protecting delicate equipment from even minor electrical surges. The 3-pole configuration ensures comprehensive protection across all phases of a three-phase system, while the high 15kA breaking capacity provides significant headroom for handling high fault currents. Its compact design facilitates efficient installation in standard distribution boards, and the high-quality manufacturing standards associated with the Eaton brand ensure long-term durability and consistent performance under varying load conditions.

Suitable for

• Sensitive electronic equipment protection
• Industrial control circuits
• Automation and PLC systems
• Laboratory and testing equipment
• Commercial electrical distribution panels

This circuit breaker may not be suitable for general-purpose household applications or circuits with high inrush currents, such as those powering large motors or transformers, as the Z-characteristic is designed for very sensitive loads and may cause nuisance tripping in standard power applications.

Key specifications

• Rated current: 0.5A
• Number of poles: 3
• Tripping characteristic: Z
• Breaking capacity: 15kA
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed to be snapped onto a standard 35mm DIN rail within an enclosure. Ensure that the supply voltage is disconnected before beginning the installation process. Connect the incoming power 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 to prevent overheating.

What to consider before purchase

• Verify that the 0.5A rating matches the specific load requirements of your equipment.
• Ensure the Z-characteristic is appropriate for the sensitivity of the connected devices.
• Confirm that the 3-pole configuration is compatible with your electrical distribution system.
• Check the available space on the DIN rail within your distribution board.

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform periodic testing of the tripping mechanism to ensure the device remains fully functional and capable of providing the necessary protection for your electrical system.
