Circuit breakers are devices used to protect electrical and electronic components from overloads and faults, and to protect personnel and equipment from hazardous currents. The R21-62-20.0A-R01CV-V is a circuit breaker from the RCF series from Mersen. These circuit breakers are designed for use in complex motor control centers, motor control panels and motor control applications.

The R21-62-20.0A-R01CV-V is a thermal magnetic breaker with a maximum current rating of 20A and rated voltage of 600V AC. It has two independently adjustable tripping mechanisms, one for overload protection and one for short-circuit protection, and an optional manual reset. The breaker also has a rapid trip feature, which can reduce the trip time by up to 50%.

The breaker is UL listed and CSA certified. It has a variety of features designed to ensure safe operation in harsh environments, such as dust and humidity. The housing is made from thermoplastic, which is resistant to corrosion, and is equipped with a locking mechanism to prevent accidental opening. The terminals are also sealed to protect against dust and moisture.

The R21-62-20.0A-R01CV-V circuit breaker has several different applications, including motor control panels and motor control centers. It can be used as a motor starter panel, motor protection panel, motor disconnect, and as a replacement for traditional fuses in motor control applications. It is also used to protect personnel and equipment from hazardous currents, and has the ability to disconnect if an overload or short circuit occurs.

The working principle of the R21-62-20.0A-R01CV-V circuit breaker is based on the thermal-magnetic trip principle. It contains a thermal element, which is heated when the current exceeds its rated value, and a magnetic element, which reacts to the current. The thermal element heat up faster than the magnetic element and trips the breaker when the current exceeds its value, while the magnetic element provides a slower trip time in order to trip the breaker in the case of short circuits.

The R21-62-20.0A-R01CV-V circuit breaker is a reliable and versatile device, which can be used in a variety of applications. It is designed with safety and reliability in mind, and can offer protection from high currents and overloads. The adjustable trip mechanism and manual reset function make it a great choice for motor control panels and motor control centers, while the rapid trip feature ensures the breaker is tripped quickly in hazardous conditions.
