EATON FAZ-K10/1 Miniature Circuit Breaker, 1P, 10A, 15kA, K-Characteristic

The EATON FAZ-K10/1 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust overcurrent and short-circuit protection in demanding electrical environments. With a rated current of 10A and a high breaking capacity of 15kA, this device is specifically designed to handle the unique electrical demands of industrial and commercial power distribution systems. Its K-type tripping characteristic is optimized for circuits that experience significant inrush currents, ensuring that the breaker remains stable during normal operation while providing rapid disconnection during genuine fault conditions.

Advantages

This miniature circuit breaker offers exceptional reliability through its advanced tripping mechanism, which is specifically calibrated for inductive and capacitive loads. The high 15kA breaking capacity provides a significant safety margin, protecting downstream equipment from severe fault currents. Its compact 1-pole design allows for efficient space utilization within distribution boards, while the durable construction ensures long-term operational stability even in challenging industrial settings. The K-characteristic provides a precise balance between sensitivity and tolerance, preventing nuisance tripping during the startup of motors or transformers.

Suitable for

• Protection of motor control circuits
• Transformers and inductive load management
• Commercial and industrial power distribution panels
• Systems with high inrush current requirements

This device may not be suitable for standard residential lighting or general-purpose outlet circuits where a B or C-type characteristic is typically required. Using a K-characteristic breaker in applications with low inrush currents may result in delayed protection during a fault, as the tripping threshold is higher than that of standard breakers.

Key specifications

• Rated current: 10A
• Number of poles: 1
• Breaking capacity: 15kA
• Tripping characteristic: K
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical codes. The breaker is designed to be snapped onto a standard DIN rail within an appropriate enclosure. Ensure that the supply voltage and load characteristics are compatible with the breaker specifications before connection. Securely tighten all terminal screws to the manufacturer's recommended torque to prevent overheating and ensure a reliable electrical connection.

What to consider before purchase

• Verify that the K-characteristic is appropriate for your specific load type
• Ensure the 15kA breaking capacity meets the requirements of your installation's short-circuit current rating
• Check the available space in your distribution board for a 1-pole module

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform periodic testing of the installation to ensure that the protection device remains fully functional and that all electrical connections remain tight and free from oxidation.
