R21-61-15.0A-B01IV-V circuit breaker is a two-pole breaker with short-circuit protection, over-current protection and overload protection. It is mainly used in electrical systems for the protection of motors, welding line, transformers, switchgear, lighting systems, and so on. This circuit breaker is suitable for operation of three-phase AC currents up to 415V and can withstand currents up to 15.0A.

The working principle of R21-61-15.0A-B01IV-V circuit breaker is based on the bi-metallic strip principle, in which a bimetallic strip is used as the heart of the circuit breaker. In this way, when a certain current passes through the bimetallic strip, the bimetallic strip is heated up, causing it to bend or warp which results in the breaking of the contacts. This opens up the electrical circuit and the current flow is interrupted. This is the process of a circuit breaker.

When using this circuit breaker, the temperature rise of bimetallic strip must be kept, then the duration for the contacts separation must meet the requirements of the relevant standard. This circuit breaker features an overload protection trip capacity and short-circuit protection trip capacity. It is also equipped with special terminals for safety devices, and it allows for multiple connection schemes, which makes it an excellent and versatile circuit breaker.

In conclusion, the R21-61-15.0A-B01IV-V circuit breaker has the important functions of thermal protection and short-circuit protection in electrical power systems. It is suitable for a wide range of applications and ensures the safe, reliable operation of the entire electrical system. This makes it an essential choice for any electrical system.
