Eaton FAZ B8/1 Miniature Circuit Breaker, 1-Pole, B-Curve, 8A, 15kA

The Eaton FAZ B8/1 is a high-performance 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for precision and reliability, this device effectively monitors current flow to prevent damage from overloads and short circuits. With its 8A rated current and B-curve tripping characteristic, it is specifically optimized for applications where sensitive equipment requires fast-acting protection. The 15kA breaking capacity ensures that the unit can safely handle significant fault currents, making it a dependable component for maintaining the integrity of electrical systems in various environments.

Advantages

This miniature circuit breaker offers exceptional operational reliability due to its high-quality construction and advanced internal mechanisms. The B-curve characteristic allows for a balanced response to current surges, providing a secure threshold for standard electrical loads. Its compact 1-pole design facilitates efficient use of space within distribution boards, while the high breaking capacity of 15kA provides an extra layer of safety against severe electrical faults. The device is built to withstand demanding conditions, ensuring long-term performance and consistent protection for connected infrastructure.

Suitable for

• Residential electrical distribution boards
• Commercial lighting and power circuits
• Industrial control panels
• Protection of sensitive electronic equipment
• AC electrical installations requiring 8A current limits

When it may not be suitable

This circuit breaker is not intended for use in DC systems, as it is specifically rated for AC applications. Furthermore, it may not be suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a C or D-curve breaker would be more appropriate to prevent nuisance tripping.

Key specifications

• Number of poles: 1
• Rated current: 8A
• Tripping characteristic: B-curve
• Breaking capacity: 15kA
• System compatibility: AC

How to use

The Eaton FAZ B8/1 is designed for installation on standard DIN rails within an electrical enclosure. Before installation, ensure the power supply is completely disconnected to prevent electrical shock. Mount the device securely onto the rail and connect the incoming supply cable to the top terminal and the outgoing load cable to the bottom terminal. Ensure all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the breaker can be switched on by moving the toggle to the upward position. If the breaker trips, investigate the cause of the overload or short circuit before resetting the toggle.

What to consider before purchase

• Verify that the 8A rating matches the requirements of your specific circuit load.
• Ensure the B-curve characteristic is appropriate for the type of equipment being protected.
• Confirm that the 15kA breaking capacity meets the short-circuit current rating of your electrical installation.
• Check available space in your distribution board for a 1-pole module.

Usage recommendations: Always consult with a qualified electrician for the installation and maintenance of circuit protection devices to ensure compliance with local electrical codes and safety standards.
