R21-69-10.0A-B06IH-V

Circuit breakers are an essential electrical component used to protect electrical circuits and wiring in industrial, commercial, and residential applications. The R21-69-10.0A-B06IH-V is a circuit breaker manufactured by Eaton that is used in high- and medium-voltage applications. This circuit breaker is designed to provide reliable protection against overcurrent and short circuit conditions while minimising nuisance tripping. In this article we will discuss the application field and working principle of the R21-69-10.0A-B06IH-V circuit breaker.

The R21-69-10.0A-B06IH-V is primarily used in industrial and commercial electrical systems. It can protect both low- and medium-voltage circuits, with a nominal operating voltage of up to 690 V. The R21-69-10.0A-B06IH-V is especially suitable for protection in motors, pumps, and switchgear. It also has a wide range of available tripping times to meet the specific needs of each application. This circuit breaker can protect up to two different circuits or two phases (three for North American applications). When compared to traditional fuses, circuit breakers provide better protection and easier replacement or resetting. The R21-69-10.0A-B06IH-V is robust and reliable, and it is designed to provide long service life and dependable protection against short circuits, overloads, and arc fault conditions.

A circuit breaker is a type of electrical switch that can be used to open and close circuits automatically. When an abnormal situation occurs and a pre-determined level of current passes through the circuit breaker, it will switch off the current. This functionality is achieved using a combination of mechanical and thermal components. The R21-69-10.0A-B06IH-V has a solenoid-operated mechanism that controls the switching function. This mechanism utilizes a coil component that creates a magnetic field when current is applied. This magnetic field is used to attract an armature, which operates an opening/closing switch. The R21-69-10.0A-B06IH-V also has an internal thermal component that can detect if the current passing through the circuit is above the maximum level. This component is usually a bimetallic strip that heats up when the current level is too high. The heating of the strip will cause it to bend, which can trigger the circuit to open. The combination of these two components allows the R21-69-10.0A-B06IH-V to provide both time-delay protection (mechanical) and instantaneous protection (thermal). This type of circuit breaker can detect both overcurrent and short circuit conditions and will quickly switch off the current in order to protect the electrical components and wiring.

In summary, the R21-69-10.0A-B06IH-V is a circuit breaker manufactured by Eaton that can be used in high- and medium-voltage applications. It is designed to provide reliable protection against overcurrent and short circuit conditions while minimising nuisance tripping. This circuit breaker can protect up to two different circuits or two phases (three for North American applications). Its protection is achieved using a combination of mechanical and thermal components, making it a very reliable and robust solution for industrial and commercial electrical systems.
