R21-62F-15.0A-R01CV-V

The R21-62F-15.0A-R01CV-V is part of a circuit breaker, a device used to automatically detect and interrupt fault currents in an electrical system. Circuit breakers are essential components of any electrical system and are designed to protect the system from damage due to overloads and short circuits. The R21-62F-15.0A-R01CV-V is an example of a air-insulated circuit breaker, a type of circuit breaker that uses air to insulate the internal contacts from each other.

The R21-62F-15.0A-R01CV-V is a manually operated, 1-pole circuit breaker with a rated current of 15.0A and a voltage rating of 1kV. It features a rotary handle and includes a microswitch in the handle that is used to turn the breaker on or off. The breaker also includes a thermal-magnetic trip unit, which is used to detect fault currents and trips the breaker when the current exceeds the rated value. The trip unit can be adjusted to provide a specific desired trip time.

The R21-62F-15.0A-R01CV-V is widely used in industrial, residential, and commercial applications. In industrial applications, it is typically used as an overcurrent protection device for the primary and secondary circuits. In residential applications, it is often used for overcurrent protection of appliance circuits and for motor control in air conditioning and compressor systems. In commercial applications, it is used for overcurrent protection of lighting circuits.

The working principle of the R21-62F-15.0A-R01CV-V is as follows. When the current passes through the circuit breaker, it flows through the air gap between the internal contacts. If the current exceeds the rated value, the air gap will be disrupted, allowing the current to jump across the gap and thus tripping the circuit breaker. The thermal-magnetic trip unit is used in combination with the main switch to detect any overload or short circuit conditions, and the tripping time can be adjusted according to the needs of the application.

In conclusion, the R21-62F-15.0A-R01CV-V is an air-insulated, manually operated, 1-pole circuit breaker that is widely used in industrial, residential, and commercial applications. It includes a thermal-magnetic trip unit which is used to detect fault currents and trips the breaker when the current exceeds the rated value. The working principle of the R21-62F-15.0A-R01CV-V is based on disrupting the air gap between the internal contacts when the current exceeds the rated value.
