MCBs – Miniature circuit breakers! Just as the name suggests, these are automatic electrical switchgear that prevents electrical hazards by curbing the electrical circuit.

The electrical circuit is broken as soon as there is an electrical overload or a short circuit. Equipment is thus, heavily safeguarded with MCBs. These are widely used in commercial as well as industrial set-ups.

Miniature circuit breakers have found their application in small-scale and large-scale industries. With 30kA of power being the most common in industrial equipment, it is recommended to make a switch from primitive fuses to the latest MCBs. Optimization of energy flow can also be obtained from state-of-the-art MCBs.

How do MCBs work?

When a current higher than the safety threshold of the machinery is generated, the MCB is triggered. They are designed intricately to diminish any false alarms. The bimetallic strip in the MCBs overheats with the excess amount of current and trips just discontinuing the electrical circuit.

The tripping of an MCB under the influence of a high current that is detrimental to the machine’s health is one-tenth of a second. In case the current is not extremely high in comparison to the safety standards of the machinery, the MCB shall respond slightly slower.

Types of MCBs

Categorized on the basis of the current each MCB trips on, the MCBs are classified into the following types:

  • Type B: These miniature circuit breakers are designed to trip when the electrical current exceeds the safety standard of the machinery 3-5 times.
  • Type C: These miniature circuit breakers are designed to trip when the electrical current exceeds the safety standard of the machinery 5-10 times.
  • Type D: These miniature circuit breakers are designed to trip when the electrical current exceeds the safety standard of the machinery 10-20 times.
