Product information

Description

The EATON AZ-3N-D40 is a high-performance 3P+N miniature circuit breaker engineered for robust electrical protection in industrial and commercial distribution systems. This device is specifically designed to handle high-demand electrical environments, offering a 40A rated current and an impressive 25kA breaking capacity. With its D-type tripping characteristic, it is optimized for circuits with high inrush currents, ensuring that the system remains stable during normal operation while providing rapid disconnection in the event of a short circuit or overload.

Advantages

This circuit breaker stands out due to its exceptional reliability and durability in demanding electrical installations. The 3P+N configuration allows for comprehensive protection of three-phase systems with a neutral conductor, ensuring complete circuit isolation when necessary. Its high breaking capacity of 25kA provides a significant safety margin, protecting downstream equipment from severe fault currents. The D-curve characteristic is particularly beneficial for applications involving motors, transformers, or other inductive loads that generate significant current spikes during startup, preventing nuisance tripping.

Suitable for

  • Industrial machinery and motor control centers
  • Commercial electrical distribution boards
  • Systems with high inrush current equipment
  • Large-scale lighting installations
  • Power distribution for HVAC systems

When it may not be suitable

This device is not intended for residential applications where standard B or C curve breakers are typically sufficient. Using a D-curve breaker in circuits without high inrush currents may result in delayed protection during minor faults, as it is designed to tolerate higher temporary current surges.

Key specifications

  • Rated current: 40A
  • Number of poles: 3P+N
  • Breaking capacity: 25kA
  • Tripping characteristic: D-curve
  • Application: Industrial and commercial

How to use

The EATON AZ-3N-D40 should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is designed for mounting on a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly sized for a 40A load and securely fastened to the terminals to prevent overheating. Once installed, the device can be manually switched on or off using the front-facing toggle, and it will automatically trip to the off position if an electrical fault is detected.

What to consider before purchase

  • Verify that the 40A rating matches your circuit load requirements
  • Ensure the D-curve characteristic is appropriate for your specific load type
  • Check that the enclosure has sufficient space for a 3P+N module
  • Confirm compatibility with your existing distribution board busbar system

Usage recommendations

Regularly inspect the circuit breaker for signs of thermal stress or loose connections. It is recommended to perform periodic testing of the installation to ensure the device remains functional and provides the intended level of protection for your electrical infrastructure.
