Circuit breakers are an important safety investment that protects buildings and homes from damage due to an overload of electrical current. The R21-0F..S00444154 is a type of circuit breaker that is designed and manufactured to provide reliable and cost effective protection in residential and commercial applications. In this article, we will explore the general application field and working principle of the R21-0F..S00444154 circuit breaker.

The R21-0F..S00444154 circuit breaker has several features designed to make it ideally suited to protect circuits from overload and short circuit conditions. It features a rotary switch mechanism with snap-action contact operation, allowing for precise and reliable performance with minimal manual operation required. It also features adjustable overload and short circuit protection, allowing it to be easily tailored to the specific application requirements. The rotary switch design provides for high cutting capacities and enhances its ability to handle large electrical loads. In addition, the R21-0F..S00444154 circuit breaker is equipped with a mechanical and electrical latching feature which ensures that circuit protection is maintained until it is manually reset.

In terms of application field, the R21-0F..S00444154 can be used in residential, commercial and industrial applications, providing reliable and efficient protection from short circuits and overloads. Additionally, it is designed to be compatible with other types of circuit breakers and is also suitable for use as a main switch in both single and three-phase networks.

In terms of its working principle, the R21-0F..S00444154 circuit breaker relies on the use of a bimetallic element, a type of temperature sensitive metal, to detect the temperature that is generated by an overload or short circuit event. The temperature increase causes the bimetallic element to bend, creating enough force to set off the circuit breaker. As the temperature increases, so does the force, and this force eventually trips the circuit breaker, cutting off the power supply and preventing further damage.

The R21-0F..S00444154 circuit breaker is a reliable and cost-effective solution for protecting circuits from overload and short circuit conditions. Its adjustable parameters make it suitable for practically any environment, and the mechanical and electrical latching features ensure that the circuit protection is maintained until it is manually reset. Furthermore, its wide application field and the use of a temperature sensitive bimetallic element make it well suited for use in almost any residential, commercial, or industrial setting.
