Eaton FAZ-C40/1 Miniature Circuit Breaker, 1-Pole, C-Curve, 40A, 15kA

The Eaton FAZ-C40/1 is a high-performance 1-pole miniature circuit breaker engineered to provide robust protection against overcurrent and short-circuit conditions in electrical systems. Designed for demanding environments, this device ensures reliable operation and safety in AC power distribution networks. With its precise C-curve tripping characteristic and a 40A rated current, it effectively manages electrical loads while maintaining system integrity.

Advantages

This circuit breaker stands out due to its high breaking capacity of 15kA, which allows it to handle significant fault currents safely. Its compact 1-pole design facilitates efficient space utilization within distribution boards and control panels. The Eaton FAZ series is recognized for its durability and consistent performance, minimizing the risk of nuisance tripping while providing rapid response times during actual electrical faults. The robust construction ensures long-term reliability in both commercial and industrial settings.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Protection of lighting and heating circuits
• Control panel installations

When it may not be suitable

This device is not intended for use in DC power systems or applications requiring different tripping characteristics, such as sensitive electronic equipment that may necessitate a B-curve breaker. It is also not suitable for installations where the rated current exceeds 40A or where the prospective short-circuit current is higher than the 15kA rating.

Key specifications

• Number of poles: 1
• Rated current: 40A
• Tripping characteristic: C-curve
• Breaking capacity: 15kA
• Voltage type: AC

How to use

The Eaton FAZ-C40/1 is designed for mounting on a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Ensure that the supply power is disconnected before beginning the installation. Secure the device firmly onto the rail and connect the incoming and outgoing conductors to the appropriate terminals, ensuring that all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

• Verify that the 40A rating matches your circuit load requirements
• Ensure the C-curve characteristic is appropriate for your specific application
• Check that the 15kA breaking capacity meets the safety requirements of your electrical installation
• Confirm compatibility with your existing DIN rail distribution board

Usage recommendations

Regular inspection of the circuit breaker and its connections is recommended to ensure continued operational safety. If the breaker trips, investigate the cause of the fault before resetting the device. Do not attempt to modify or repair the internal mechanism of the circuit breaker.
