Circuit breakers are essential pieces of equipment common in many industrial and electrical installations. They are designed to protect devices, wiring and other components from overloading or other damage due to a current surge or other external conditions. The R21-2-16.0A-B121CV-S is an industrial circuit breaker, specifically designed to provide protection to systems against overcurrents, undervoltages and other disruptions.The R21-2-16.0A-B121CV-S is a residual current circuit breaker with integrated overload, earth leakage protection and surge protection, also known as a RCBO - Residual Current Breaker/Overload. It is designed to monitor the current flowing through the circuit and automatically trips if it senses a sustained, dangerous amount of current. It is a single pole earth leakage differential circuit breaker that is rated for 16.0A and has a fixed sensitivity of 30mA.The R21-2-16.0A-B121CV-S is designed for use in any industrial or commercial environment where protection from overcurrents, undervoltage and earth leakage need to be monitored and managed. It is suitable for all installations that require monitoring of both electrical and fire safety protection and has a wide range of applications including protection of general distribution, motor and lighting circuits, private and commercial buildings, residential and industrial premises, and equipment in hazardous areas.The working principle of the R21-2-16.0A-B121CV-S is based on the current-difference principle. It consists of a live and neutral residual current monitoring circuit and an impedance. When the residual current detector senses a difference in the current flowing through the live and neutral conductors, the circuit trips and shuts off the power supply, preventing any surges or overcurrents from damaging the system and any connected components. The circuit breaker is automatic and will reset itself after the fault is corrected, allowing the system to start again without having to manually switch it back on.The R21-2-16.0A-B121CV-S is also equipped with an integrated overload protection and surge protection module which helps to further protect components connected to the system. This protection module can be adjusted with the sensitivity being set in accordance to the system requirements with a trip level of 30mA – 600mA, making it a versatile tool for multiple scenarios.The R21-2-16.0A-B121CV-S is a reliable and cost-effective solution for the protection of circuits and devices from overvoltages, undervoltage and earth leakage. Its small size and flexibility makes it ideal for all circuit protection applications, from residential and commercial to hazardous areas. With its integrated overload and surge protection, the R21-2-16.0A-B121CV-S is a dependable and reliable circuit breaker for all types of installations.
