Circuit breakers are an electrical device designed to protect an electrical system from overloads and short circuits. They are commonly used in residential, commercial, and industrial applications, and can be found almost everywhere. The R21-0..00426156 is an example of a circuit breaker, and is commonly used in the transport industry. This article will discuss the application field and working principle of this specific model.

The R21-0..00426156 circuit breaker can be used in a variety of applications, such as industrial control devices, building automation, safety systems, panel boards, junction boxes, machine control panels, and many others. It is also suitable for automotive and marine applications as well. It has a UL 489 listing, meaning it meets the standard requirements for circuit breakers and has been rated in accordance with the Underwriters Laboratories standard. It has a maximum current rating of 21 Amps, a voltage rating of 440 volts, and can operate at temperatures ranging from -20℃ to +80℃.

In order to understand how the R21-0..00426156 circuit breaker works, it is important to understand what happens when too much current flows through a circuit. When an electrical circuit is overloaded, the electrical components inside the circuit become heated due to resistance in the circuit. The excessive heat generated can damage the components and cause a fire. To protect the circuit from becoming overloaded and overloaded, circuit breakers are required.

The R21-0..00426156 circuit breaker has three main components. These components include a contact system, a sensitivity system, and a trip mechanism. The contact system consists of two contact plates which make or break the electrical connection to the circuit. These contact plates are attached to a moveable armature and when a certain amount of current passes through the contacts, the armature moves and the circuit is opened. This is known as tripping the circuit breaker.

The sensitivity system is an additional device which is installed in order to detect when the current flowing through the circuit reaches a certain level. If the current exceeds the pre-determined level, the sensitivity system will activate the trip mechanism. This mechanism causes the moveable armature to move and opens the contacts, thus opening the circuit and preventing further current flow.

The R21-0..00426156 circuit breaker is rated to withstand a wide range of temperatures, from -20℃ to +80℃. This rating is important to ensure that the circuit breaker will not be damaged by extreme temperatures. In addition to temperature, the R21-0..00426156 circuit breaker is also designed to be resistant to moisture, dust and other contaminants. This ensures that the circuit breaker will last longer and will be more reliable in the long run.

Overall, the R21-0..00426156 circuit breaker is a reliable and durable device. Its high quality and rugged design ensures that it will protect circuits from overloads and short circuits. Its wide range of applications and capabilities make it the perfect choice for a variety of purposes. Whether it is for building automation, industrial control devices, or machine control panels, the R21-0..00426156 circuit breaker will help protect circuits from potential damage or malfunction caused by excessive current.
