 What is a RCD breaker | how it's Works

Today we studied about the most important electrical element, which is the differential cutter, also known as a Residual Current Device breaker, The differential cutter plays an important role in protecting electrical circuits and wires from the leakage of electric current and short circuits.

It was necessary to find a solution to the problem of electrification and electric shocks and prevent electrical fires which the electric rationing is exposed, and since the need or the invention, the so-called differential cutter was invented to ensure and protect the electricians and ordinary people from electric shocks, whether by direct or indirect touch.

The differential cutter components: 

generally consist of four inlets, two poles to enter the phase wire, the neutral wire and the two poles the outside to exit the same wires, the phase wire and the neutre wire. By measuring the strength of the current Electric, and the intensity of the current out.

Important note 

There are RCD that contain four inputs and outlets, which are for three-phase electrical systems.

RCD three phases 

The differential cutter working principle:

the differential cutter consists of the inner poles and the output poles. The input current does not disconnect the power, but when a bare wire is touched by a person or the short circuit , which means that there is a leakage of the electrical current, the differential cuts immediately cut off the house , electrical.

The internal components of the differential cutter:

 The differential cutter contains no and electrical Shiites that allow for measurement of output and input current changes, allowing the differential cutter to disconnect the power immediately after any leakage of the electric current, whether by direct or indirect touch. This means that there is a difference between the output current and the input current, so when the differential cutter protects you from all forms of electrical hardness, not like a Fusible, which only protects the surcharge and short circuits.

Protection Against Electric Shocks.

Fire Prevention.

Ground Fault Protection. 

Conclusion:

RCDs are commonly installed in areas where electrical safety is paramount, such as bathrooms, kitchens, outdoor outlets, and workshops. They are a crucial component of electrical safety systems and are designed to save lives and prevent electrical accidents.

This was a simple topic about the differential cutter and how it works inside the electrical facility and the houses. Don't forget to tell us in a comment if you find any ambiguity in the matter.
