Types of electrical circuit breakers

 There are several types of electrical circuit breakers, including:

1. Miniature Circuit Breakers (MCBs): Used for low-voltage circuits, they protect against overloads and short circuits.

2. Moulded Case Circuit Breakers (MCCBs): Used for higher voltages, they offer adjustable trip settings and improved protection.

3. Air Circuit Breakers (ACBs): Used for high-voltage applications, they provide fast protection and are often used in industrial settings.

4. Vacuum Circuit Breakers (VCBs): Used for high-voltage applications, they offer fast protection and are known for their reliability.

5. Oil Circuit Breakers (OCBs): Used for high-voltage applications, they use oil to extinguish arcs and provide protection.

6. Gas Circuit Breakers (GCBs): Used for high-voltage applications, they use gas to extinguish arcs and provide protection.

7. Arc Fault Circuit Interrupters (AFCIs): Specialized breakers that detect and interrupt arcing faults, which can cause electrical fires.

8. Ground Fault Circuit Interrupters (GFCIs): Specialized breakers that detect and interrupt ground faults, which can cause electrical shock.

These are some of the main types of circuit breakers, and the specific type used depends on the application, voltage level, and protective requirements.
