The Role of Electric Breakers in Electrical Safety

Electricity, a crucial part of our daily lives in the current times, has brightened up our homes and powered the factories. While it has been playing a major role, electrical safety is an important aspect to consider. Electric circuit breakers are basically the safety component in electric circuits. It plays a significant part in safeguarding the electrical systems. In order to understand how an electric breaker helps to ensure safety, let's understand what electric breakers are and how they function.

Understanding Electric Breakers?

These safety devices are installed to protect electrical systems from any potential danger. An electric breaker operates on thermal effects and electromagnetism principles. Overload and short circuits are the two main causes of disruption in an electrical system protected by a switch and trip mechanism. Here, an electric breaker acts as a switch that turns off the electricity flow automatically. Thus, helping prevent any serious damage. An electric circuit consists of a trip and a switch mechanism.

In the switch mechanism, the current flows seamlessly through the circuit when it is operating in a normal manner. When the flowing current exceeds the breaker's rated capacity, a short circuit occurs, and the switch mechanism detects it, triggering the trip mechanism. In a fraction of a second, the electric breaker comes into play by interrupting the current flow and preventing further damage.

Moving ahead, let's discuss the several types of electric circuit breakers, each designed for a specific application.

What are The Different Types of Electric Breakers?

There are several types of electric circuit breakers, each designed for specific applications and levels of protection. Here are the most common types:

  1. Miniature Circuit Breaker or MCB: These circuit breakers are popularly used in residential and commercial buildings. They protect against short circuits and overloading circuits with lower current ratings. Their compact size and availability in various current ratings help match different circuit requirements.

  2. Moulded Case Circuit Breaker or MCCB: These manually operated circuit breakers are more robust than MCBs. Like an MCB, they are commonly used in industrial and commercial settings. While offering higher current ratings, they can protect larger electrical systems, like overloads and short circuits. Moreover, MCCBs have adjustable trip settings, which are beneficial for maintenance.

  3. Residual Current Circuit Breaker or RCCB: Also known as a Ground Fault Circuit Interrupter (GFCI), an RCCB aims to make detecting imbalances in electrical currents easier. An imbalance can occur due to any leakage or ground faults. In order to prevent electric shocks, it quickly cuts off the power supply.

  4. Earth Leakage Circuit Breaker or ELCB: ELCBs, also called residual current devices (RCDs), are similar to RCCBs. Their unique design protects against electrical shocks which occur due to ground faults.

An important tip for installing an electric circuit is to note that different regions have different circuit breakers. It is advised to consult an electrician or a reputed power solutions company to ensure compliance and a thorough selection of circuit breakers.

What are the Benefits of Electric Circuit Breakers?

The foremost benefit of electric breakers is enhancing electrical safety by detecting overloads and short circuits. While the breakers immediately interrupt the flow of electricity, they are an indication of energy's efficient use. Electric circuit breakers have a trip mechanism that instantly alerts, cutting off the direct connection between devices and power equipment.

They prevent damage by regulating the current flow, ensuring it remains within safe limits. By tripping during overloads or short circuits, circuit breakers shield appliances, motors, and other electrical components from excessive heat and potential failure.


Electric breakers are indispensable components of an electrical system. While they offer a host of benefits ensuring safety, it also protects the equipment and provides convenience. By embracing an electric breaker, businesses and individuals enjoy electrical safety and reduced maintenance costs.
