Circuit Breakers
The R21-62-20.0A-35703-1-V is an all-round circuit breaker, especially suitable for providing the safety and protection of the circuit, machine and personnel. It has the advantages of safety, reliability, stability, small size and high current. Moreover, it can effectively prevent the over-heated and over-loaded conditions of the circuit.
Application Field of R21-62-20.0A-35703-1-V
The application fields of the R21-62-20.0A-35703-1-V mainly include protection and control of power distribution systems, power stations, industrial equipments and so on. In particular, it can be used to protect and control the running situation of compressors, boilers, transformers and other electrical equipments in industrial, petrochemical, and energy industries. Moreover, this product is particularly suitable for use in places with heavy starting current or intermittent operation; or places with serious fluctuation of operation current.
Working Principle of R21-62-20.0A-35703-1-V
The working principle of the R21-62-20.0A-35703-1-V is based on the principle of “temperature-electricity”. Its temperature is determined by the equipped temperature control switch. When the current in the working circuit exceeded the corresponding action current value, the temperature control switch will be activated to initiate the safety protection circuit. In other words, it has the ability to cut off the circuit whenever it finds an abnormality.
The R21-62-20.0A-35703-1-V is equipped with a temperature control switch, which is connected in series with the upstream and downstream of the circuit breaker. The temperature control switch is responsible for detecting the temperature changes. When the temperature exceeds the predetermined temperature, the temperature control switch will immediately cut off the circuit to realize reliable protection.
The R21-62-20.0A-35703-1-V is fitted with a magnetic alloy core, which serves to improve the electrical contact reliability of the circuit breaker and make it more reliable. The magnetic alloy core is made up of two different parts, one is connected to the main circuit, and the other is connected to the circuit breaker coil.
Therefore, when the current passes through the magnetic alloy core, a strong magnetic field is generated, which can reduce the contact resistance to almost zero and make the contact of the circuit breaker more reliable. In addition, the magnetic alloy core can also make the circuit breaker work stably over a long period of time, even in long-term interrupting operation.
Moreover, the R21-62-20.0A-35703-1-V is equipped with a special over-current limit, which can accurately test the over-current condition of circuit. When the circuit current that passing through exceeds the over-current limit value, the over-current limit will immediately cut off the circuit.
Conclusion
All in all, the R21-62-20.0A-35703-1-V is a multi-functional and reliable circuit breaker, which can provide safety and protection for the circuit, machine and personnel. Moreover, it has the advantages of safety, reliability, stability, small size, high current, and can effectively prevent the over-heated and over-loaded conditions of the circuit.
