Circuit breakers are essential safety components in any electrical systems. They protect both the system and the people working with them from harm by easily interrupting the flow of electric current. The R21 1-1.00A-B121EH is a popular circuit breaker manufactured by Schneider Electric. So what is the application field and working principle of the R21 1-1.00A-B121EH?

The R21 1-1.00A-B121EH is an EtherNet circuit breaker, which is a type of circuit breaker that includes an EtherNet port. This makes it possible for remote monitoring and control using EtherNet. This type of breaker is used in industrial and commercial applications, such as HVAC and lighting systems, where greater control and monitoring is required. It is also used in some residential applications, such as in motorhome or yacht applications.

The working principle of the R21 1-1.00A-B121EH is the same as most other circuit breakers. When the current in an electrical circuit exceeds the rated amperage of the circuit breaker, the circuit breaker trips and opens the circuit. This prevents further flow of current in the circuit, preventing any potential damage due to further overload. The circuit breaker can then be reset by pushing the reset button, which will close the circuit again. This is a very simple but effective way to protect an electrical system from any potential damage due to overload.

The R21 1-1.00A-B121EH also has several safety features that make it even safer than other types of circuit breakers. It features a thermal-magnetic trip system, which reacts quickly to current overloads, but is slow enough to prevent false trips. It also has a manual reset button, which can be used to reset the breaker without having to power off the system. Finally, it also has an integrated arc fault detection and lockout feature, which prevents overloads from occurring due to arcing or sparking.

The R21 1-1.00A-B121EH is a reliable, safe and cost effective circuit breaker, suitable for both industrial and commercial applications. It is easy to install, and its EtherNet port makes it easy to remotely monitor and control the circuit breaker from any location. This makes it an ideal choice for any application where reliable power protection is needed.
