Product Information
Full details
This Eaton Moeller xEffect series FAZ Miniature Circuit Breaker (MCB) is designed for electrical protection in AC circuits up to 230V. It offers a reliable 4A current rating, a 2-pole configuration for comprehensive circuit isolation, and a Type S characteristic for specific tripping behavior, making it ideal for electricians and system installers. While providing a robust 10 kA breaking capacity, users should note its specific AC voltage limitation and the need for flush-mounted installation.

FAQs
What is the breaking capacity of this circuit breaker?
This Eaton FAZ Miniature Circuit Breaker has a breaking capacity of 10 kA.
What type of installation is required for this breaker?
This circuit breaker is designed for flush-mounted installation.
What is the maximum AC voltage this breaker can handle?
The rated AC voltage for this breaker is up to 230V.
What is the conductor size range supported by this breaker?
It supports connectable conductor cross-sections for both multi-wired and solid-core conductors ranging from 1 to 25 mm².
What does the 'Type S' characteristic mean?
The 'Type S' characteristic refers to a specific tripping curve that dictates how quickly the breaker reacts to overcurrents. This is designed for particular applications requiring precise protection thresholds.
What is the operating temperature range for this device?
The circuit breaker can operate in ambient temperatures from -25°C to 75°C.
Does this breaker offer protection against water ingress?
This breaker has a degree of protection of IP20, meaning it is protected against solid objects greater than 12.5mm but not against water.
Troubleshooting
Circuit breaker trips frequently without apparent overload
Check for loose wiring connections, ensure the connected load does not exceed the 4A rating, or verify that the Type S characteristic is appropriate for the load type. Consider consulting a qualified electrician.
Breaker will not reset after tripping
Ensure the fault has been cleared and the circuit is no longer overloaded. If the breaker remains tripped, it may be damaged and require replacement. Do not attempt to force it.
No power to the circuit protected by the breaker
Verify that the circuit breaker is in the ON position. Check upstream power sources and connections. If the breaker has tripped, identify and resolve the cause before resetting.

Setup, Compatibility & Care
Setup:
This Miniature Circuit Breaker is designed for flush-mounted installation within a compatible electrical enclosure. It occupies two modular spaces on a standard DIN rail. Ensure that the circuit to be protected does not exceed the breaker's 4A rating. Connect conductors using appropriate terminals, ensuring solid or multi-wired conductors within the 1 to 25 mm² range are securely fastened.
Compatibility:
Compatible with AC systems up to 230V and a frequency range of 50-60 Hz. It supports additional equipment, indicating compatibility with busbars and other modular devices. Ensure the ambient temperature falls within the operational range of -25°C to 75°C.
Care:
Regular inspection of electrical installations is recommended. Clean the exterior of the breaker with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners. Ensure the terminal connections remain tight and free from corrosion. Periodically check for proper tripping function by manually operating the toggle switch (if safely accessible and applicable for testing procedures).
