EATON AZ-2-C50 Miniature Circuit Breaker, 2-Pole, C-Curve, 50A, 25kA

The EATON AZ-2-C50 is a robust 2-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in demanding environments. With a rated current of 50A and a high breaking capacity of 25kA, this device is specifically designed to manage power distribution safely and efficiently. Its C-curve tripping characteristic makes it suitable for applications where moderate inrush currents are expected, ensuring that the circuit remains protected against overloads and short circuits.

Advantages

This circuit breaker offers exceptional reliability and durability, meeting the rigorous standards required for industrial and commercial electrical installations. The 25kA breaking capacity provides a significant safety margin, allowing the device to handle high fault currents effectively. Its compact 2-pole design facilitates easy integration into standard distribution boards, while the high-quality construction ensures long-term operational stability and minimal maintenance requirements.

Suitable for

• Industrial power distribution systems
• Commercial building electrical panels
• Protection of motors and lighting circuits with moderate inrush currents
• AC electrical installations requiring high short-circuit protection

When it may not be suitable

This device is not intended for use in DC electrical systems or residential applications where a lower breaking capacity is sufficient and more cost-effective. It is also not suitable for circuits requiring B-curve or D-curve tripping characteristics, as the C-curve is specifically calibrated for standard inductive and resistive loads.

Key specifications

• Number of poles: 2
• Rated current: 50A
• Tripping characteristic: C-curve
• Breaking capacity: 25kA
• System type: AC

How to use

The EATON AZ-2-C50 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 appropriate distribution enclosure. Ensure that the supply cables are securely connected to the terminals and that the torque settings specified by the manufacturer are followed to prevent loose connections. Once installed, the breaker can be manually switched on or off using the toggle lever, and it will automatically trip to the off position in the event of an electrical fault.

What to consider before purchase

• Verify that the 50A rating matches the requirements of your electrical circuit
• Ensure the 25kA breaking capacity is appropriate for the prospective fault current at the installation point
• Confirm that the C-curve characteristic is compatible with the connected load types
• Check the available space in your distribution board for a 2-pole device

Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic testing of the switching mechanism to ensure continued functionality. Do not attempt to bypass or modify the internal tripping mechanism, as this compromises safety and voids the warranty.
