Circuit breakers are electrical components that are used to protect electrical systems from overload and short circuits. The R21-61-20.0A-35663-1-V is a type of circuit breaker that is used in a variety of applications. This article will discuss the application fields and working principles of the R21-61-20.0A-35663-1-V.

The R21-61-20.0A-35663-1-V is a low-voltage, low-current circuit breaker with a rated current of 20.0A， suitable for up to 690V AC three-phase systems. It can be used in many different applications, such as commercial and residential buildings, manufacturing plants, and power distribution systems. The breaker is capable of controlling the on/off of current to provide protection and reliability.

The working principle of the R21-61-20.0A-35663-1-V can be divided into two parts. Firstly, when the current exceeds the preset level, the breaker will trip and isolate the over-currents quickly by using a tripping mechanism. Secondly, the overload current will be detected and the breaker will trip, thus providing protection for the system and the components. The trip current is adjustable and the electrical connections are reliable and secure.

In addition, the R21-61-20.0A-35663-1-V is equipped with an insulation envelope and terminal cover for additional protection against dust and moisture as well as providing safety for operators. The breaker can operate in temperatures ranging from -25℃ to +70℃. Furthermore, the enclosure is made from plastic and flame-retardant material, making it suitable for use in hazardous environments where flammable gases are present.

In conclusion, the R21-61-20.0A-35663-1-V circuit breaker is suitable for a variety of applications and is designed to provide reliable and secure protection against overloads and short circuits. The adjustable trip current and temperature operating range makes it a versatile and reliable option for preventing damages to the electrical system and its components.
