Product Information
Full details
The Eaton FAZ-S6/1 is a compact, single-pole miniature circuit breaker (MCB) designed for reliable overcurrent protection in electrical installations. Ideal for electricians and system integrators needing a dependable safety device, its primary benefit is robust protection with a 10 kA breaking capacity. A minor caveat is its specific Type A tripping characteristic, which should be matched to the circuit's requirements.

FAQs
What does 'Type S' tripping characteristic mean?
A Type S tripping characteristic indicates a delayed response to overcurrents, designed to prevent nuisance tripping on inrush current while still providing protection against sustained overloads and short circuits. It typically has a higher pick-up current for short-duration surges compared to a Type B or C breaker.
What is the breaking capacity of this circuit breaker?
The Eaton FAZ-S6/1 has a breaking capacity of 10 kA (kiloamperes), meaning it can safely interrupt fault currents up to 10,000 Amps.
Can this breaker be used in a 120V AC system?
While rated for 240V AC, it will function in a 120V AC system. However, its primary rating is optimized for 230V/240V applications.
How do I reset the circuit breaker after it trips?
To reset the breaker, first identify and resolve the cause of the trip. Then, simply move the operating lever back to the 'ON' position.
What is the operating temperature range?
The operating temperature range for this circuit breaker is -25 °C to 75 °C (-13 °F to 167 °F).
Is this breaker suitable for DC circuits?
This circuit breaker is designed for AC (Alternating Current) circuits and is not recommended for DC (Direct Current) applications.
What does IP20 mean?
IP20 is an Ingress Protection rating that signifies the device is protected against solid objects greater than 12.5 mm (like fingers) but offers no protection against water or moisture.
Troubleshooting
Breaker trips frequently under normal load.
Verify the load current does not exceed the 6A rating. Check for potential short circuits or faulty appliances on the protected circuit. Ensure the tripping characteristic (Type S) is appropriate for the connected load.
Breaker does not trip when a fault occurs.
Confirm the breaker is correctly installed and energized. Check wiring connections. If the issue persists, the breaker may be faulty and requires replacement.
Difficulty mounting on DIN rail.
Ensure you are using a standard 35mm top hat DIN rail. The 3-position clip may require a specific sequence for attachment or release; consult installation guides if unsure.
Contact Position Indicator (CPI) is not visible or clear.
The CPI should clearly indicate the ON/OFF state. If unclear, ensure no obstructions. The breaker may require inspection or replacement if the indicator is internally damaged.
Pros and Cons
Pros
- Compact 17.5mm width for space-saving installations.
- High breaking capacity (10 kA) provides robust fault protection.
- Easy identification of contact status via CPI.
- Secure DIN rail mounting with a 3-position clip.
- Durable construction typical of Eaton products.
Cons
- Specific Type A tripping characteristic may not be suitable for all applications.
- Single-pole design is limited to single-phase circuits.
- IP20 rating requires protection from dust and moisture in the installation environment.
Setup, Compatibility & Care
Setup:
- Ensure the main power to the distribution board is switched off.
- Mount the FAZ-S6/1 onto a standard 35mm DIN rail using the integrated 3-position clip. The clip allows for easy removal from an existing busbar.
- Connect the line conductor to the top terminal and the load conductor to the bottom terminal using the window and elevator terminals. Ensure connections are tight.
- Verify the contact position indicator (CPI) is in the OFF position before energizing.
- Carefully re-energize the circuit.
Compatibility:
- Mounting: Compatible with standard 35mm top hat DIN rails.
- Voltage: Designed for 230V AC systems.
- Current: Suitable for circuits rated at 6A.
- Environment: Rated IP20, meaning it is protected against solid objects larger than 12.5mm but not against water. It must be installed within an enclosure or panel.
Care:
- Regularly inspect the breaker for any signs of damage or overheating.
- Keep the installation environment clean and free from dust and moisture to maintain the IP20 rating.
- Ensure terminals remain clean and connections are secure.
