Circuit Breakers

Circuit breakers are important components found in many electrical and electronic installations. Functionally, they are designed to provide protection against overcurrents, short-circuiting, and over or under voltages. A circuit breaker is essentially an electrically-controlled switch that opens its contacts when it detects an undesired condition in a circuit, thereby disconnecting the circuit and preventing electric shock, fires and other dangerous conditions.

R21-2-20.0A-R102CV-V application field and working principle

The R21-2-20.0A-R102CV-V is a circuit breaker used for the protection of low-voltage electrical systems up to 1A. It has a single-pole design and is suitable for residential, light commercial and industrial applications. The circuit breaker features an adjustable tripping threshold, an adjustable time delay, and a manual reset button.

The working principle of the R21-2-20.0A-R102CV-V circuit breaker is simple. When the current in the circuit exceeds the preset tripping threshold, the breaker trips and interrupts the circuit, protecting it from dangerous overcurrent conditions. The adjustable time delay allows the breaker to be configured to trip at different times depending on the application. The manual reset button can be used to reset the breaker after any fault or to restart the circuit when necessary.

The R21-2-20.0A-R102CV-V circuit breaker is a reliable, easy to install and maintain product that provides the necessary protection for low-voltage circuit applications. With its adjustable time delay and tripping threshold, it is an ideal choice for residential, commercial and industrial applications.
