What are The Categories and Advantages of RCBO?

The word RCBO stands for “Residual Current Breaker with Over-current” stands for “Residual Current Breaker with Over-current.” An MCB and an RCD are combined in this electronic system (residual current device). An MCB protects us from over-current hazards such as:

Overload – this happens when a circuit is overloaded with too many machines drawing power from it.

Short-circuit – a short-circuit happens when the live and neutral wires/conductors of a circuit make contact. This floods the circuit with a massive amount of current, wreaking havoc.

A residual current detector (RCD) protects a circuit from residual current and earth leakage. This happens when a break in the circuit is triggered by faulty wiring or human activity, allowing current to flow out and causing an electrical shock to the human. Both of these faults are covered by an RCBO.

Types of RCBOs

As previously mentioned, an RCBO is a combination of an MCB and an RCCB.

The Following Types of MCBs are Dependent on Tripping Curves:

• Type B- MCBs are used in domestic and light commercial applications where the surge of power is reduced.

• Type C- These are usually used for high inductive loads, such as small motors and fluorescent lighting, where switching surges are high. They can trip at five to ten times their rated present.

• Type D- These trip ten to twenty-five times in an instant and are used in heavy industrial facilities such as winding motor factories, X-ray machines, and compressors.

Single, two, three, or four-pole models are available.

Categories of RCBO

In general, RCBOs are classified according to their RCCB configuration. RCBOs with a Type-B/Type-C circuit breaker and a Type-AC/Type-A RCCB is also available from manufacturers. Other combinations of RCCBs and MCBs must be manually and separately connected to the circuit if they are needed.

Factors to Consider While Selecting an RCBO

Be sure to choose an RCBO that is suitable for the setup.

While Type AC RCCBs are common in RCBOs, their use when upgrading installations necessitates careful consideration because most circuits now include appliances that can generate various types of residual fault current.

Overload, current ranking, and short circuit power must all be considered when choosing RCBOs.
