## Long description

The EATON FAZ-B63/3 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical distribution systems. This device is designed to safeguard circuits against overloads and short circuits, ensuring operational safety in both residential and industrial environments. With a rated current of 63A and a high breaking capacity of 15kA, it offers reliable performance under demanding electrical conditions.
Advantages
This miniature circuit breaker stands out due to its high breaking capacity, which allows it to handle significant fault currents safely. The B-type tripping characteristic makes it particularly effective for circuits with low inrush currents, such as lighting and heating systems. Its 3-pole design enables simultaneous disconnection of all phases, providing comprehensive protection for three-phase electrical installations. The robust construction ensures long-term durability and consistent performance in various professional electrical setups.
Suitable for
Three-phase electrical distribution boards
Lighting circuits in commercial buildings
Heating and resistive load protection
Industrial control panels
Residential electrical infrastructure
When it may not be suitable
This circuit breaker is not intended for applications requiring a C or D tripping characteristic, such as circuits with high inrush currents from motors or large transformers, where nuisance tripping might occur. It is also not suitable for single-phase installations where a 1-pole or 2-pole breaker would be more space-efficient.
Key specifications
Number of poles: 3
Rated current: 63A
Tripping characteristic: B
Breaking capacity: 15kA
Mounting type: DIN rail
How to use
The device should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly sized for a 63A load and securely fastened to the terminals. After installation, verify the connections and perform a functional test to ensure the breaker operates correctly within the circuit configuration.
What to consider before purchase
Verify that the 63A rating matches your circuit requirements
Ensure the B-characteristic is appropriate for your specific load type
Check available space in your distribution board for a 3-pole device
Confirm that the 15kA breaking capacity meets local safety standards
Usage recommendations
Always ensure that the electrical system is de-energized before beginning installation. Regularly inspect the circuit breaker for signs of wear or heat damage to maintain optimal safety and performance.
