In this blog post, we will discuss the precautions for using this high-quality circuit breaker, along with its numerous advantages and features. By following these guidelines, you can ensure the optimum performance and longevity of your electrical system.

Altitude and Temperature Considerations:
It is important to note that the YEM3-125/3P molded case circuit breaker is designed to be used at altitudes of up to 2000m. This feature allows you to install and operate this breaker in various settings without compromising its performance. Additionally, the recommended temperature range for best results is between -5°C and +40°C. By adhering to these guidelines, you can rely on the YEM3-125/3P to function flawlessly even in challenging environmental conditions.

Optimal Air Humidity for Maximum Efficiency:
Maintaining the right air humidity is essential for the proper functioning of the circuit breaker. The YEM3-125/3P is designed to operate under a maximum relative air humidity of 50% at +40°C. However, as the temperature decreases, the acceptable humidity levels increase. For example, at 20°C, the circuit breaker can handle relative humidity levels of up to 90%. Nonetheless, it is important to take special measures to prevent condensation caused by temperature changes, as this can affect the efficiency of the breaker.

Dependability in Harsh Environments:
The YEM3-125/3P molded case circuit breaker is engineered to operate reliably even in polluted environments. It is designed for pollution degree 3, ensuring long-term functionality under moderate levels of pollution. The main circuit of the breaker falls under category III, while the auxiliary and control circuits belong to category II. This categorization ensures that the YEM3-125/3P can withstand various levels of electrical interference, making it suitable for a wide range of applications.

Uncompromised Safety Measures:
To maintain the safety and integrity of your electrical system, it is important to consider the electromagnetic environment in which the circuit breaker will be used. The YEM3-125/3P molded case circuit breaker is specifically designed for use in areas free from explosion hazards, conductive dust, corrosive metals, and gases that can compromise insulation. This ensures that the breaker operates optimally while mitigating any potential risks.

Protection Against the Elements:
As an electrical device, the YEM3-125/3P molded case circuit breaker should be installed in a location that is shielded from rain and snow. By keeping the breaker in a dry environment, you reduce the risk of water damage and subsequent malfunctions. This precaution ensures that your electrical system remains protected and functions without interruption.

Storage Recommendations:
Lastly, for proper maintenance and protection of the YEM3-125/3P molded case circuit breaker when not in use, it is crucial to adhere to specific storage conditions. The breaker should be stored within a temperature range of -40°C to +70°C. Following this guideline guarantees that the breaker remains in an optimal condition, ready for use whenever needed.

Conclusion:
The YEM3-125/3P molded case circuit breaker is an exceptional electrical device that offers both safety and reliability. By following the precautions for use mentioned above, you can maximize the performance and longevity of this product in your electrical system. Its ability to function at different altitudes, temperature ranges, and air humidities, along with its resistance to pollution and reliability in diverse environments, makes the YEM3-125/3P a valuable asset in any electrical setup.
