Eaton FAZ-Z2/3 Miniature Circuit Breaker, 3-Pole, Z-Characteristic, 2A, 15kA

The Eaton FAZ-Z2/3 is a high-performance 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. With a rated current of 2A and a Z-characteristic curve, this device is specifically designed to handle applications where precise and rapid overcurrent protection is essential for sensitive electronic components and control circuits. Its robust construction and 15kA breaking capacity ensure consistent performance and safety within complex electrical distribution systems.

Advantages

This miniature circuit breaker offers exceptional reliability due to its specialized Z-characteristic, which provides a tighter tripping range compared to standard curves, making it ideal for protecting delicate equipment. The 3-pole configuration allows for simultaneous disconnection of all phases, enhancing safety during maintenance or fault conditions. Its high breaking capacity of 15kA ensures that the device can effectively interrupt significant short-circuit currents, thereby preventing damage to downstream infrastructure and minimizing downtime in industrial or commercial settings.

Suitable for

• Protection of sensitive electronic control circuits
• Industrial automation and measurement equipment
• Commercial electrical distribution panels
• Systems requiring precise overcurrent protection

This circuit breaker may not be suitable for general-purpose household lighting or standard power outlet circuits, as the Z-characteristic is specifically tuned for low-current, sensitive applications. Using it in high-inrush current environments, such as those involving large motors or transformers, may lead to nuisance tripping.

Key specifications

• Number of poles: 3
• Rated current: 2A
• Tripping characteristic: Z
• Breaking capacity: 15kA
• Mounting type: DIN rail

The device is designed for installation on a standard DIN rail within an electrical distribution board. It should be installed by a qualified professional in accordance with local electrical regulations. Ensure that the supply voltage and load requirements are compatible with the device specifications before installation. Once mounted, the toggle switch allows for manual operation to connect or disconnect the circuit as needed.

What to consider before purchase

• Verify that the Z-characteristic is appropriate for your specific load type
• Ensure the 2A rated current matches the circuit requirements
• Confirm compatibility with your existing DIN rail enclosure
• Check that the 15kA breaking capacity meets the short-circuit current rating of your installation

Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or discoloration. Periodically test the mechanical operation of the toggle switch to ensure it moves freely. If the breaker trips, investigate the cause of the overcurrent before resetting the device.
