## Long description

The EATON AZ-4-D100 is a robust 4-pole miniature circuit breaker engineered for demanding industrial and commercial electrical distribution environments. This high-performance device provides reliable protection against short circuits and overloads, ensuring the safety and integrity of complex electrical systems. With a rated current of 100A and a substantial breaking capacity of 25kA, it is specifically designed to handle the rigorous demands of modern power distribution.
Advantages
The primary advantage of this circuit breaker is its D-type tripping characteristic, which allows it to withstand high inrush currents without nuisance tripping. This makes it an essential component for protecting circuits connected to equipment that draws significant power upon startup. Its 4-pole configuration provides comprehensive control and protection across all phases and the neutral conductor, enhancing overall system safety. The high breaking capacity of 25kA ensures that the device can safely interrupt significant fault currents, protecting downstream equipment from catastrophic damage.
Suitable for
Industrial machinery and motor control centers
Large-scale commercial electrical distribution boards
Systems with high-inductive loads
Equipment with significant startup inrush currents
When it may not be suitable
This circuit breaker is not intended for standard residential lighting or small appliance circuits, as the D-curve characteristic is specifically tuned for high-current applications. Using this device in low-load residential environments may result in inadequate protection for sensitive electronics.
Key specifications
Number of poles: 4
Rated current: 100A
Breaking capacity: 25kA
Tripping characteristic: D-curve
Application: Industrial and commercial
How to use
The EATON AZ-4-D100 should be installed by a qualified electrician within a standard distribution board or enclosure. It is designed for DIN-rail mounting. Ensure that the supply cables are correctly sized for a 100A load and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the device can be manually switched on or off using the front-facing toggle.
What to consider before purchase
Verify that the D-curve characteristic matches your load requirements
Ensure the 25kA breaking capacity is sufficient for your installation's prospective short-circuit current
Confirm that your distribution board has enough space for a 4-pole device
Usage recommendations
Regularly inspect the circuit breaker for signs of thermal damage or loose connections. If the breaker trips, investigate the cause of the fault before resetting the device to ensure the safety of the electrical installation.
