2023-07-17

Molded Case circuit breaker (MCCB):
- MCCBs are larger in size and are typically used for higher current ratings, usually ranging from 100A to 2500A.
- They are designed to provide protection against overcurrent, short circuit, and ground fault conditions.
- MCCBs are commonly used in industrial and commercial applications, such as power distribution systems, motor control centers, and large machinery.
- They have adjustable trip settings, allowing for customization based on the specific application requirements.

- MCCBs are more expensive compared to miniature circuit breakers.

Miniature Circuit Breaker (MCB):
- MCBs are smaller in size and are typically used for lower current ratings, usually ranging from 1A to 125A.
- They are designed to provide protection against overcurrent and short circuit conditions.
- MCBs are commonly used in residential, commercial, and light industrial applications, such as electrical panels, lighting circuits, and small appliances.
- They have fixed trip settings, which are usually standardized based on the current rating.
- MCBs are more affordable compared to molded case circuit breakers.

Overall, the main difference between MCCBs and MCBs is their size, current rating, and application suitability. MCCBs are used for higher current applications in industrial and commercial settings, while MCBs are used for lower current applications in residential, commercial, and light industrial settings.
