Eaton FAZ-C3/2 Miniature Circuit Breaker 2P C 3A 15kA AC

The Eaton FAZ-C3/2 is a high-performance 2-pole miniature circuit breaker engineered to provide robust protection against overcurrent and short-circuit events in electrical systems. Designed for demanding environments, this device ensures the safety of circuits and connected equipment by interrupting power flow when faults are detected. Its reliable construction and precise tripping mechanisms make it a standard choice for maintaining operational continuity in AC power distribution networks.

Advantages

This circuit breaker offers exceptional reliability due to its high breaking capacity of 15kA, which allows it to handle significant fault currents without compromising performance. The C-type tripping characteristic provides a balanced response, making it ideal for applications with moderate inrush currents. Its compact 2-pole design facilitates efficient use of space in distribution boards, while the robust internal components ensure a long service life and consistent protection under various load conditions.

Suitable for

• Industrial electrical distribution systems
• Commercial building power installations
• Protection of control circuits
• Lighting and small motor applications

This device may not be suitable for applications requiring a different tripping curve, such as sensitive electronic equipment that might need a B-type characteristic, or high-inrush machinery that could trigger nuisance tripping with a C-type curve. It is specifically designed for AC systems and should not be used in DC circuits unless explicitly rated for such use.

Key specifications

• Number of poles: 2
• Rated current: 3A
• Tripping characteristic: C
• Breaking capacity: 15kA
• Voltage type: AC

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

What to consider before purchase

• Verify that the 3A current rating matches your circuit requirements
• Ensure the 15kA breaking capacity is sufficient for your installation's prospective short-circuit current
• Confirm that the C-type tripping curve is appropriate for your specific load type
• Check that the 2-pole configuration aligns with your wiring system

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform periodic testing of the switching mechanism to ensure it remains functional and responsive.
