Circuit breakers are essential safety devices that are used to protect electrical circuits in both residential and industrial settings. The R21-1-1.00A-B02EH is a type of circuit breaker designed to protect lighting systems which is suitable for use in commercial, industrial and residential areas. In this article, we will discuss its application field and working principle.

The R21-1-1.00A-B02EH is a two-pole mini circuit breaker which can be used for a variety of applications in places such as commercial buildings, industrial plants and residential settings. It features a thermal-magnetic operation and has a current rating of 10A. It also comes with a full range of accessories such as mounting brackets, cords, terminals and reset buttons. It has a compact size which allows it to be installed in tight spaces and comes with a five-year warranty.

The most common application for the R21-1-1.00A-B02EH is in lighting systems, in both commercial and residential areas. It is designed to protect lighting systems from being overloaded or short-circuited which can result in electrical fires. It is also used in some industrial settings, such as industrial machinery, where it can provide protection for the equipment from the power supply.

The working principle of the R21-1-1.00A-B02EH is quite simple. It is designed to be activated when too much current passes through it. When triggered, it will cut off the power supply, thus preventing further damage to the electronics. The activation of the breaker happens in two stages. The first is the thermal stage, where the breaker is triggered when the current exceeds the current rating. The second is the magnetic stage, where the breaker is tripped when the current continues to increase even after the thermal stage is activated.

The installation of the R21-1-1.00A-B02EH requires that the breaker be connected to an AC power supply and the lighting system. It is also important that the ground fault protection be in place, as this will protect the circuit from further damages due to short-circuiting. Once installed, it is important to regularly check the breaker and connection for wear and tear as this can lead to malfunctioning.

In conclusion, the R21-1-1.00A-B02EH is a two-pole mini circuit breaker which can be used for a variety of applications such as lighting systems in commercial and residential settings and industrial machinery. Its working principle is based on a two-stage thermal-magnetic operation which helps to protect against overloads and short-circuits. The installation must be done correctly to ensure that the breaker is correctly wired and that the ground fault protection is in place. Regularly checking the breaker and connection is important to ensure that it is working properly and that any necessary maintenance is done.
