Industrial circuit breaker types

There are several types of industrial circuit breakers, each designed to meet specific requirements and applications. Here are some common types of industrial circuit breakers:

  1. Molded Case Circuit Breakers (MCCBs): These are the most common type of industrial circuit breaker. They are designed for indoor use and are available in a range of sizes and ratings.
  2. Air Circuit Breakers (ACBs): These circuit breakers use air as the arc-quenching medium and are designed for indoor and outdoor use. They are commonly used in medium-voltage applications.
  3. Oil Circuit Breakers (OCBs): These circuit breakers use oil as the arc-quenching medium and are designed for high-voltage applications. They are commonly used in power transmission and distribution systems.
  4. Vacuum Circuit Breakers (VCBs): These circuit breakers use a vacuum as the arc-quenching medium and are designed for high-voltage applications. They are commonly used in power transmission and distribution systems.
  5. Gas Circuit Breakers (GCBs): These circuit breakers use a gas, such as sulfur hexafluoride (SF6), as the arc-quenching medium and are designed for high-voltage applications. They are commonly used in power transmission and distribution systems.
  6. Low-Voltage Power Circuit Breakers (LVPs): These circuit breakers are designed for low-voltage applications (up to 600V) and are commonly used in industrial control panels and switchgear.
  7. Medium-Voltage Power Circuit Breakers (MVPs): These circuit breakers are designed for medium-voltage applications (600V to 35kV) and are commonly used in industrial power distribution systems.
  8. High-Voltage Power Circuit Breakers (HVPs): These circuit breakers are designed for high-voltage applications (above 35kV) and are commonly used in power transmission and distribution systems.
  9. Ring Main Unit (RMU) Circuit Breakers: These circuit breakers are designed for use in ring main systems, which are used to distribute power in industrial and commercial applications.
  10. Compact Circuit Breakers (CCBs): These circuit breakers are designed for use in compact switchgear and are commonly used in industrial control panels and switchgear.
  11. Modular Circuit Breakers (MCBs): These circuit breakers are designed for use in modular switchgear and are commonly used in industrial control panels and switchgear.
  12. Smart Circuit Breakers: These circuit breakers are designed with advanced features such as remote monitoring and control, and are commonly used in industrial and commercial applications.

Each type of industrial circuit breaker has its own unique characteristics, advantages, and disadvantages, and the choice of which type to use depends on the specific application and requirements.
