The Role of Circuit Breakers in Modern Electrical Systems

Circuit breakers are automatic devices designed to interrupt the flow of electricity when faults such as overloads or short circuits occur.

How Do Circuit Breakers Work?

They detect excessive current and automatically trip the circuit to stop the flow of electricity, preventing damage or fire.

Types of Breakers

• Miniature Circuit Breakers (MCB): For residential and light commercial use.
• Molded Case Circuit Breakers (MCCB): Used in industrial systems with higher current ratings.
• RCD/RCB: Provide protection from earth leakage and electric shock.

Conclusion

Choosing the right type of breaker is key to ensuring electrical safety and compliance with local standards.
