Why Is RCCB Used?

13th Aug 2022

A Residual Current Circuit Breaker (RCCB) protects against a leakage current from the live conductor to the earth. This type of breaker senses the presence of current and automatically disengages the circuit to prevent an accident or electric shock. 

They operate according to Kirchhoff’s Current Law, which states that incoming and outgoing currents should be equal. This principle can help you save lives by preventing electrocution and injury.

RCCBs protect against earth leakage and all types of leakage current. Because they do not rely on individual earthing devices, they can automatically break the circuit if the live current is exceeded. 

They are easy to install and are designed to protect against voltage fluctuation. This makes them essential for high-voltage commercial setups. If you want to protect your home and family from electrical hazards, get an RCCB.

Why Is RCCB Used?

The reason behind the RCCB’s operation is to prevent an electrical shock or an earth fault. There are two parts to this device: the phase coil and the neutral coil. When there is no fault in the circuit, these two coils will carry equal current. 

The phase coil will be wrapped in one direction, while the neutral coil will be wrapped in the opposite direction. If there is a fault in the circuit, the phase and neutral coils will become energized, and the current will flow through the sensing coil.

The human body can only withstand an electric shock of up to 30 mA. When that level of current is exceeded, it can cause respiratory paralysis and prickling sensations. The RCCB protects against life-threatening electrical shock by tripping the circuit at the first sign of a small change in the residual current. This mechanism also protects against fire hazards. 

The sensitivity of an RCCB varies. The 30-mA rated circuit breaker is more sensitive than the 100-mA one. The 30mA range is safe for most people. A 100-mA RCCB is only effective in a few cases. In these cases, the RCCB will prevent electrocution and save a life. If a fire happens in your home, an RCCB will automatically disconnect the circuit.

The Uses and Applications of RCCB

When you’re looking for ways to keep your house safe from electrical shocks, you’ve probably come across the uses and applications of the RCCB. However, you may be wondering what this device is used for. In this article, we’ll go over some of the common uses and applications of the RCCB. 

Residual Current Circuit Breakers (RCCBs) protect you from electrical shock by sensing the difference in current between the line and the neutral conductor. A healthy circuit will have an equal balance of both currents, but an unexpected fault can cause an imbalance between the two currents. 

The RCCB can detect this imbalance and trip the circuit, protecting you from serious injury. In addition, this device is especially useful when you’re dealing with unexpected earth faults, such as when someone accidentally contacts a live wire.

An RCCB can help you save money while improving your quality of life. Today, people are using more household appliances that can cause electrical hazards, including lightning and power lines. 

This makes it more important than ever to keep everyone safe. Installing an RCCB is a simple, affordable, and effective solution. Civil houses and buildings are one of the main applications of the RCCB. For these reasons, it is essential to install an RCCB in your home to ensure its safety.

The RCCB is an excellent choice for many uses. It has a built-in window that allows you to view the ON and OFF buttons. However, some manufacturers have made advanced technology to create RCCBs that protect against both short circuits and earth faults. Some RCCBs are even better than MCBs for some applications. Therefore, the use of an RCCB should be considered in your home before you purchase one.
