Circuit Breakers are essential components in electrical systems, and they are used to control and protect the flow of electricity and protect machines and equipment from physical damage.1E20UM Circuit breakers provide enhanced safety, reliability and performance for a wide range of electrical applications. In this article, we will discuss the application field and working principle of 1E20UM circuit breakers.

Application Field of 1E20UM Circuit Breakers

The 1E20UM Circuit Breakers are used in a wide range of applications, including the following:

• Residential, commercial, and industrial load centers;
• Distribution panels and subpanels;
• Pumps, fans, and compressors;
• Heating and air conditioning systems;
• Conveyors, machine tools and factory automation;
• Lighting systems;
• Power supplies;
• Electrical motors;
• UPS systems; and
• Any other application requiring protection from overcurrents and shorts.

The 1E20UM series of circuit breakers is also used in outdoor environments, and is rated for use in both wet and dry locations. The breakers are also UL listed, which gives them extra durability and reliability.

Working Principle of 1E20UM Circuit Breakers

1E20UM Circuit Breakers are based on a mechanical overload trip mechanism, which is designed to open the circuit when the current load becomes too great. The mechanism relies on the force of a heat-sensitive, spring-loaded bimetal strip to trip the breaker. The 1E20UM series also features a trip-free mechanism, which ensures that the breaker cannot be reset until the overload has been cleared. This ensures a safe and reliable operation of the breaker.

The breakers also have a built-in overcurrent protection feature, which helps to protect the breaker from damage if an overcurrent occurs. In the event of an overload, the mechanism trips the breaker, interrupting the flow of electricity and protecting the equipment and devices connected to it.

1E20UM Circuit Breakers are available in a variety of configurations, including single pole, double pole and three pole models, as well as thermal-magnetic and magnetically operated models. The breakers are also rated for use at different voltage levels and can handle up to 18,000 Amps of current. Additionally, the breakers are compliant with the latest IEC Standard 60947-2, ensuring their safety and reliability.

Conclusion

The 1E20UM Series of Circuit Breakers are a reliable and safe way to protect your equipment and devices from potential damage caused by overcurrents and shorts. The circuit breaker offers a range of features, including an overload-trip mechanism, overcurrent protection, and a trip-free mechanism, making it a safe and reliable option for a variety of applications. Additionally, the breakers are available in a range of configurations and are compliant with the latest IEC 60947-2 Standard, ensuring their safety and reliability.
