Circuit breakers play an important role in electrical power systems, preventing damage not only to the equipment but also to personnel. The R21-62-2.00A-B01CV-V is a type of circuit breaker that is mainly used in high voltage applications. It is a two-pole device and is often employed in single-phase and three-phase systems. It also has additional protection against over current and overload. This article will discuss the device’s application field and working principle.

Application Field and Operating Conditions

The R21-62-2.00A-B01CV-V circuit breaker is mainly used for industrial applications in high and medium voltage networks. It has a breaking capacity of 50 kA with a rated operating voltage of AC 1,000V and an operating voltage of AC 500V to 690V. The device also has an anticipated life of 20,000 operations with an operating temperature range of -40°C to +40°C. The device is also very compact compared to other circuit breakers, measuring in at 122mm (L) x 76.5mm (W) x 56mm (H).

Design and Working Principle

The R21-62-2.00A-B01CV-V circuit breaker is a two-pole, normally-closed device that is designed to detect and prevent the occurrence of over-current, overload and short circuits in an electrical power system. It contains a thermal-magnetic trip unit, which is designed to detect over-currents and thermal overloads. It also contains a voltage-sensing mechanism, which can detect over-voltage and the presence of a short-circuit.

The mechanism operates by monitoring the electrical current that passes through the system. If the current exceeds a certain level, the thermal-magnetic trip unit will trip, and the contacts of the circuit breaker will open. The voltage-sensing mechanism operates in a similar fashion, but monitors the voltage and will trip if it exceeds a predetermined level.

For both mechanisms, once the trip is triggered, the contacts of the circuit breaker will open, breaking the circuit and preventing the electrical current from continuing to flow. This will provide protection to any equipment connected to the circuit and will also protect personnel from potential hazards.

Conclusion

The R21-62-2.00A-B01CV-V is a two-pole, normally-closed circuit breaker that is designed for industrial applications in high and medium voltage circuits. It features a thermal-magnetic trip unit and voltage-sensing mechanism for detecting and preventing overloads, over-currents and short-circuits. This provides effective protection for the equipment and personnel connected to the power system.
