Eaton FAZ-K2/1 Miniature Circuit Breaker 1P 2A 15kA K-Curve

The Eaton FAZ-K2/1 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection against overcurrents and short circuits in demanding electrical environments. With a rated current of 2A and a high breaking capacity of 15kA, this device is specifically designed to handle the unique requirements of circuits that experience significant inrush currents. Its K-type tripping characteristic ensures that the breaker remains stable during temporary surges while providing rapid disconnection during genuine fault conditions, making it a reliable component for modern electrical distribution systems.

Advantages

This circuit breaker offers exceptional reliability due to its high breaking capacity, which allows it to safely interrupt fault currents in industrial and commercial settings. The K-curve characteristic is specifically optimized for applications involving motors, transformers, and other inductive loads that generate high starting currents, preventing nuisance tripping. Its modular design facilitates easy installation on standard DIN rails, ensuring seamless integration into existing switchgear and distribution boards while maintaining high safety standards for connected equipment.

Suitable for

• Protection of control circuits and sensitive electronic equipment
• Industrial motor control centers
• Transformers and inductive load circuits
• Commercial electrical distribution panels

This device may not be suitable for standard residential lighting or general-purpose socket circuits where a B or C-curve characteristic is typically required. Using a K-curve breaker in circuits without high inrush current characteristics may result in delayed protection during a fault.

Key specifications

• Number of poles: 1
• Rated current: 2A
• Breaking capacity: 15kA
• Tripping characteristic: K-curve
• Mounting type: DIN rail

To install the Eaton FAZ-K2/1, ensure the power supply is disconnected and mount the device onto a standard 35mm DIN rail within a distribution enclosure. Connect the supply line to the upper terminal and the load wire to the lower terminal, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, verify the circuit integrity before restoring power to the system.

What to consider before purchase

• Verify that the K-curve characteristic matches the specific inrush current profile of your connected load
• Ensure the 2A rated current is appropriate for the connected circuit's load requirements
• Confirm that the 15kA breaking capacity meets the short-circuit current rating of your electrical installation

For optimal performance and safety, always ensure that the circuit breaker is installed by a qualified electrician in accordance with local electrical regulations and that the terminal connections are inspected periodically for tightness.
