FAQ

What are circuit breakers?

By definition, a circuit breaker is an electrical safety device, a switch that automatically interrupts the current of an overloaded electric circuit, ground faults, or short circuits. Circuit breakers “trip”, shut off, and current flow after protective relays detect a fault.

What are the three types of circuit breakers?

A circuit breaker is an electrical safety device, specifically a switch that instantly interrupts the current of an overloaded electric circuit, ground faults, or short circuits. After protective relays detect a defect, circuit breakers “trip”, shut off, and current flow.

What is the function of circuit breakers and its types?

Circuit breaker functions. Circuit breakers are essential for protecting branch circuits from overloads, short circuits, and ground faults. Circuit breakers are switches that may open circuits safely and then be locked open to service/troubleshoot and isolate branch circuits, electrical devices, and equipment.

What is the working principle of a circuit breaker?

The circuit breaker is an electromechanical device that protects electrical systems and is commonly used in distribution boards. It operates by halting the electric current when it exceeds its design limits, preventing energy from reaching the loads and causing circuit damage.

How do I identify a circuit breaker?

The circuit breaker is an electromechanical device that protects electrical systems and is commonly used in distribution boards. It operates by halting the electric current when it exceeds its design limits, preventing energy from reaching the loads and causing circuit damage.
