Circuit breaker types pictures

Here are some common types of circuit breakers with pictures:

  1. Molded Case Circuit Breaker (MCCB)

MCCBs are the most common type of circuit breaker. They are designed for indoor use and are available in a range of ampere ratings.

  1. Air Circuit Breaker (ACB)

ACBs are similar to MCCBs but are designed for outdoor use. They are often used in industrial and commercial applications.

  1. Miniature Circuit Breaker (MCB)

MCBs are smaller and more compact than MCCBs. They are often used in residential and commercial applications.

  1. Ground Fault Circuit Interrupter (GFCI)

GFCIs are designed to protect against ground faults, which can occur when a person comes into contact with a live wire. They are often used in bathrooms, kitchens, and outdoor areas.

  1. Arc Fault Circuit Interrupter (AFCI)

AFCIs are designed to detect and interrupt arcing faults, which can occur when a wire is damaged or worn out. They are often used in residential applications.

  1. Molded Case Switch (MCS)

MCSs are similar to MCCBs but do not have overcurrent protection. They are often used in applications where overcurrent protection is not required.

  1. Vacuum Circuit Breaker (VCB)

VCBs use a vacuum interrupter to interrupt the circuit. They are often used in high-voltage applications.

  1. Sulfur Hexafluoride (SF6) Circuit Breaker

SF6 circuit breakers use sulfur hexafluoride gas to quench the arc when the circuit is interrupted. They are often used in high-voltage applications.

  1. Thyristor-Controlled Circuit Breaker (TCCB)

TCCBs use thyristors to control the flow of current. They are often used in applications where precise current control is required.

  1. Static Transfer Switch (STS)
