How A Residual Current Circuit Breaker Can Save Lives & Appliances?

The Residual Current Circuit Breaker or the Residual Current Circuit Breaker with Overload Protection is a must-have for all homes. These electric switches for home provide protection to both human lives and home appliances.

Body:

The leading switchgear manufacturers offer two crucial types of circuit breakers that increase safety and protect your home’s circuit. The first one is the Residual Current Circuit Breaker (RCCB) and second one is the Residual Current Circuit Breaker with Overload Protection (RCBO). This guide explains the key features and importance of these two types of devices from the perspective of human safety and circuit protection.

Residual Current Circuit Breaker

The Residual Current Circuit Breaker (RCCB) plays a crucial role in protecting your home or office’s electrical circuits. This current sensing system will automatically disconnect the circuit if there is a fault or excess current. This unit also prevents or reduces the risk of electronic shock, fire and electrocution.

The RCCB is also beneficial in protecting from sudden earth fault. If an earth fault occurs, this high voltage switchgear will automatically trip the circuit. This will protect you from an electric shock.

Potential Risks of Improper Earthing

In order to understand the importance of these electric switches for home it is important to know about the risks that improper earthing can pose. Many houses are not properly earthed and many are simply not earthed at all. The risk is especially higher in older homes. Even if you have installed properly earthed system, poor connections can render it ineffective. This is why you should have your home’s earthing checked every year. It can result in leakage current and create risks at different places in your home.

An unearthed electrical system poses the risks of electrical shock and fire. An RCCB from the top circuit breaker manufacturers can provide excellent level of protection from such hazards. If you are using an unearthed device, you are at the highest risk of getting an electric shock because current will move through the path of least resistance, which is your body. If there is no earthing connection, your body will become one. It could even prove to be fatal.

Benefits of Residual Current Circuit Breaker

The key benefits of a Residual Current Circuit Breaker are as following:

  • The RCCB offers protection against earth fault and leakage current.
  • The moment the rated sensitivity exceeds, it will automatically disconnect the circuit.
  • Provides safety against voltage fluctuations.

Some high voltage switchgear also have dual termination feature for both busbar and cable connections.

Residual Current Circuit Breaker with Overload Protection (RCBO)

The RCBO is a system designed by circuit breaker manufacturers for providing protection against current overload, short circuit and earth leakage current. This unit will sense any of these faults and will trip the circuit to provide protection to both the appliances and human life. It is a compact system that combines the benefits of protection for human life, wiring and appliances in the same unit.

The RCBO circuit breaker uses to ensure its own protection against overload. This eliminates any risk of overload because of high load currents. Each circuit will have a dedicated RCBO unit and if there is fault current in a single circuit, only that circuit gets switched off.

These electric switches for home are a must-have for all homes. They ensure optimal protection for you, your loved ones and your expensive appliances. In fact, no residential circuit should be designed without a Residual Current Circuit Breaker or Residual Current Circuit Breaker with Overload Protection.
