Product Information
Full details
This Eaton Moeller series xEffect FAZ Miniature Circuit Breaker (MCB) is designed for commercial and industrial applications requiring reliable overcurrent protection. It offers a 10 kA breaking capacity and a Type C tripping characteristic, suitable for loads with moderate inrush currents, providing a key benefit of robust protection for sensitive equipment. A potential caveat is its AC and DC voltage limitations, requiring careful consideration for specific power systems.

FAQs
What is the main purpose of a Type C tripping characteristic?
A Type C tripping characteristic is designed to withstand moderate inrush currents (typically 5 to 10 times the rated current) that occur briefly when certain types of equipment, like motors or fluorescent lights, are switched on. This prevents nuisance tripping while still providing protection against short circuits.
What is the breaking capacity of this circuit breaker?
The Eaton FAZ-C1/1 circuit breaker has a breaking capacity of 10 kA (kiloamperes), meaning it can safely interrupt fault currents up to this level.
Can this breaker be used for DC circuits?
Yes, it can be used for DC circuits, but only up to a maximum voltage of 48V DC.
What is the physical size and mounting method?
The breaker has a width of 17.7mm and is designed for mounting on a standard 35mm DIN rail.
What is the acceptable conductor size for connection?
The connectable conductor cross-section for both multi-wired and solid-core conductors ranges from 1mm² to 25mm².
What does the IP20 rating mean?
IP20 indicates that the device is protected against solid objects greater than 12.5mm (like a finger) but offers no protection against water. It should be installed in an enclosure to prevent contact and dust ingress.
What is the operating temperature range?
The breaker can operate reliably in ambient temperatures ranging from -25°C to 75°C.
Troubleshooting
Breaker trips frequently under normal load.
Verify the connected load does not exceed the 1A rated current. Check for short circuits in the downstream wiring. Ensure the tripping characteristic (Type C) is appropriate for the connected equipment's inrush current.
Breaker does not trip during a fault.
Ensure the breaker is correctly wired and energized. Check for loose connections. If the issue persists, the breaker may be faulty and requires replacement.
Breaker feels warm to the touch during operation.
A slight warmth may be normal. However, if it is excessively hot, check conductor connections for tightness and ensure conductors are within the specified cross-section range (1-25mm²). Overloading or a failing breaker could also be the cause.
Pros and Cons
Pros
- Compact 1-pole design saves space in electrical panels.
- Type C characteristic is suitable for a wide range of industrial and commercial loads.
- High breaking capacity (10 kA) ensures safety during fault conditions.
- Durable construction for long-term reliability in demanding environments.
- Easy DIN rail mounting simplifies installation and maintenance.
Cons
- Limited to 1 Ampere rated current, not suitable for high-power circuits.
- DC voltage rating is limited to 48V, restricting use in some DC systems.
- IP20 degree of protection requires installation in an enclosure to protect against physical contact and dust.
Setup, Compatibility & Care
Setup:
- Mounting: Mount the FAZ-C1/1 MCB onto a standard 35mm DIN rail. Ensure it snaps securely into place.
- Wiring: Connect the incoming power conductor to the line terminal and the outgoing conductor to the load terminal. Use appropriate connectors and ensure compliance with local electrical codes. The connectable conductor cross-section for both multi-wired and solid-core conductors is 1 to 25mm².
- Voltage Considerations: Ensure the circuit's operating voltage does not exceed 240V AC or 48V DC.
Compatibility:
- Suitable for AC circuits operating at 50-60Hz.
- Compatible with DC circuits up to 48V.
- Designed for use in standard electrical enclosures due to its IP20 rating.
- Use with conductor sizes ranging from 1mm² to 25mm².
Care:
- Regularly inspect the breaker for any signs of physical damage or overheating.
- Keep the area around the breaker clean and free from dust and debris.
- Ensure ventilation around the electrical panel is adequate, especially if multiple devices are installed.
- Only qualified personnel should perform maintenance or inspections.
