Introduction to R21-0-12.0A-B01CH Circuit breakers

A circuit breaker, often abbreviated as a CB, is an electrical switch that can quickly break an electrical circuit without experiencing damage to itself and can, after an interruption, automatically reset to an “on” position. Circuit breakers provide over-current protection and prevent damage to connected electrical devices in the event of a fault. In many cases, circuit breakers can also be reset from a remote location, eliminating the need to access the electrical pane.The R21-0-12.0A-B01CH circuit breaker is designed and manufactured according to IEC/EN 60947-2. It has high breaking capacity and rated current of 12A, which can perfectly meet the needs of different systems. The contact of the R21-0-12.0A-B01CH has low internal resistance and excellent thermal stability, and the power is not affected by changes in the environment. These characteristics make it particularly suitable for the protection of cables, wires and motor applications.

Application Field of R21-0-12.0A-B01CH Circuit Breakers

The R21-0-12.0A-B01CH circuit breaker is suitable for applications in residential, commercial and industrial buildings. It is also suitable for equipment with a rated 0.45-12A current, such as general lighting, connection of wall sockets, air conditioners, ranges and electric radiators. In addition, the R21-0-12.0A-B01CH circuit breaker can be used to protect transformers and the line of electric motors.

Working Principle of R21-0-12.0A-B01CH Circuit Breakers

The R21-0-12.0A-B01CH circuit breaker works by automatically disconnecting the power to an electrical circuit in an event of an overload or short circuit. When an overload or short circuit occurs in the connected electrical system, the current flowing through the circuit will increase, causing the built-in protection components to heat up. When the temperature exceeds a certain level, the bimetallic strip will flex and make contact with a trip bar, releasing the toggle mechanism that interrupts the power flow.The R21-0-12.0A-B01CH circuit breaker provides a manual reset by pushing a button after the trip. This enables the user to reset the circuit breaker and restore power to the circuit, as long as the fault condition has been rectified.

Conclusion

The R21-0-12.0A-B01CH circuit breaker is a reliable and cost effective protection device. It has a low rated current of 12A and a high breaking capacity that provides overload, short-circuit, load shedding, and load diversion protection for the connected system. The manual reset and remote reset features make it suitable for residential and industrial applications, providing safe and reliable protection to the connected components and structure.
