Circuit Breakers

The R21-2-10.0A-B121CV-V circuit breaker is a reliable line protector designed to protect low voltage power systems from overcurrent and short-circuit faults. It is suitable for both residential and commercial applications, providing quick and reliable protection in case of an overcurrent or short-circuit fault.

Application Field

R21-2-10.0A-B121CV-V circuit breaker is suitable for both residential and commercial applications. It can be used in a variety of electrical structures, such as power distribution systems, power stations, motor protection systems, and household consumer boards. It is mainly used as an over-current protector in these structures.

Working Principle

R21-2-10.0A-B121CV-V circuit breaker uses the principle of over-current protection. When the current through the protected device exceeds the rated current, the circuit breaker will automatically open the circuit, thus preventing further current flow and preventing the line from being damaged. The circuit breaker is designed to be sensitive and accurate in detecting over-current and short-circuit conditions, providing an enhanced level of safety for its application.

The circuit breaker has a built-in thermal overload release, which acts as a thermal backup. This device monitors the temperature of the protected device and if it exceeds the rated temperature it will trip the breaker, thus providing an additional layer of protection against overheating and other potential hazards.

The circuit breaker also has an adjustable trip current setting, allowing it to be used in a variety of applications. This setting can be adjusted to meet the specific needs of the application, avoiding the need to purchase multiple breakers.

R21-2-10.0A-B121CV-V circuit breaker is designed to provide reliable and accurate protection for low voltage power systems. It is easy to install and is suitable for a variety of applications. It is also designed to be reliable and accurate in detecting over-current and short-circuit conditions, providing an enhanced level of safety for its application.
