Circuit breakers are a type of safety device that protects an electrical system from overloading. Circuit breakers are designed so that when an electrical overload occurs, they automatically interrupt the flow of power to the circuit, preventing it from being exposed to further damage. The 3DU10R is a circuit breaker designed to be used in a variety of residential, commercial, and industrial applications. This article will discuss the 3DU10R\'s application field and working principle.

The 3DU10R circuit breaker is designed to be used in single-phase, three-phase, and four-wire applications. It is suitable for overcurrent protection of circuits that supply power to refrigerators, compressors, furnaces, air conditioners, and other connected appliances. It is rated for a maximum continuous current of 10A and can handle up to 15A of current. The 3DU10R is suitable for use in both 60A and 100A circuit breakers. The breaker is also UL 943 tested to ensure the highest level of safety.

The 3DU10R circuit breaker works by detecting when an overload occurs. When an overload occurs, the current flowing through the circuit begins to exceed the breaker\'s maximum safe level. This causes the breaker\'s internal bimetallic strip to heat up and expand. As the strip expands, it trips the breaker, opening the circuit and interrupting the flow of power. Once the strip cools, the breaker can be reset.

The 3DU10R circuit breaker is an essential safety device for any residential, commercial, or industrial application. Its ability to detect overloads and trip to open the circuit ensures that circuits are not damaged due to excessive current levels. Its UL 943 testing ensures the highest level of safety. The 3DU10R is a reliable circuit breaker that is suitable for a wide range of applications.
