What is a residual current circuit breaker and how do they work?
Residual current circuit breakers are electrical protection devices used to detect and deactivate an abnormal electrical current in a circuit. They are also known as “residual current circuit breakers” or “RCD”. These devices are designed to detect and deactivate an earth leakage current, which can be dangerous to people and appliances.

A differential switch consists of a transformer and a current measuring device. The transformer measures the current difference between the active and neutral poles of a circuit. If the current difference is greater than normal, the residual current circuit breaker deactivates the circuit to prevent possible electrocution.

Residual current circuit breakers are common in residential, commercial and industrial electrical circuits and are used to protect people from earth leakage currents. They are required in some countries by electrical safety regulations and it is advisable to have them at home to avoid possible electrical accidents.
Why are they called circuit breakers?
Residual current circuit breakers are also called “automatic” because they act automatically to deactivate the circuit when an abnormal current is detected. That is, they do not require human intervention to activate, but act immediately to deactivate the circuit when an abnormal current is detected. This allows the earth leakage circuit breakers to detect and deactivate an earth leakage current quickly and efficiently, which increases electrical safety in the home or place where it is installed.
