EATON AZ-3-C80 Miniature Circuit Breaker 3P C 80A 20kA AC

The EATON AZ-3-C80 is a robust 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in demanding environments. With a rated current of 80A and a high breaking capacity of 20kA, this device is specifically designed to handle significant electrical loads while maintaining system integrity. It utilizes a C-curve tripping characteristic, making it an ideal choice for applications where moderate inrush currents are expected, such as lighting and motor circuits.

Advantages

This circuit breaker offers exceptional reliability and safety for industrial and commercial power distribution systems. Its high breaking capacity ensures that the device can effectively interrupt high fault currents, thereby protecting downstream equipment from damage. The 3-pole design allows for the simultaneous disconnection of all three phases, providing a comprehensive safety solution for three-phase electrical installations. The durable construction ensures long-term performance even under continuous operational stress.

Suitable for

• Industrial power distribution panels
• Commercial building electrical systems
• Motor control circuits
• Lighting systems with moderate inrush currents
• Protection of main supply lines

When it may not be suitable

This device is not intended for residential applications where lower current ratings are typically required. It is also not suitable for DC power systems, as it is specifically designed for AC electrical installations.

Key specifications

• Number of poles: 3
• Rated current: 80A
• Tripping characteristic: C-curve
• Breaking capacity: 20kA
• Voltage type: AC

How to use

The EATON AZ-3-C80 should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is designed for mounting on a standard DIN rail within an electrical distribution board. Ensure that the supply cables are securely connected to the terminals and that the torque settings specified by the manufacturer are followed to prevent overheating. Once installed, the toggle switch allows for manual operation to connect or disconnect the circuit as needed.

What to consider before purchase

• Verify that the 80A rated current matches your load requirements.
• Ensure the 20kA breaking capacity is sufficient for your installation's prospective short-circuit current.
• Confirm that the C-curve characteristic is appropriate for your specific load type.
• Check the available space in your distribution board for a 3-pole device.

Usage recommendations

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform periodic testing to ensure the mechanical operation of the toggle switch remains smooth and responsive. Always disconnect the power supply before performing any maintenance or inspection tasks on the electrical panel.
