Give five examples of current operated circuit breaker

Here are five examples of current-operated circuit breakers:

  1. Molded Case Circuit Breaker (MCCB): MCCBs are widely used in industrial and commercial applications. They have a thermal-magnetic trip mechanism that operates when the current exceeds a set value. Examples of MCCBs include the Square D QO and the Schneider Electric EasyPact.
  2. Miniature Circuit Breaker (MCB): MCBs are smaller and more compact than MCCBs. They are commonly used in residential and commercial applications. Examples of MCBs include the Schneider Electric Acti 9 and the ABB Mini Circuit Breaker.
  3. Thermal-Magnetic Circuit Breaker (TMCB): TMCBs are similar to MCCBs but have a more sensitive thermal trip mechanism. They are often used in applications where a high level of fault detection is required. Examples of TMCBs include the Siemens Sinverter and the Eaton Cutler-Hammer.
  4. Electronic Trip Circuit Breaker (ETCB): ETCBs use electronic sensors to detect current and voltage faults. They are often used in applications where high-speed tripping is required, such as in data centers and telecommunications equipment. Examples of ETCBs include the Schneider Electric EasyPact ETC and the ABB Electronic Trip Circuit Breaker.
  5. Digital Circuit Breaker (DCB): DCBs use digital sensors and algorithms to detect current and voltage faults. They are often used in applications where high accuracy and reliability are required, such as in medical equipment and aerospace systems. Examples of DCBs include the Siemens Digital Circuit Breaker and the Eaton Digital Circuit Breaker.

These are just a few examples of current-operated circuit breakers. There are many other types and brands available, each with their own unique features and applications.
