Tips: Difference between miniature circuit breaker and molded case circuit breaker

Miniature circuit breaker
Miniature circuit breaker, short for MCB, is a circuit breaker product with a very large range and quantity. Its main function is to provide protection for building electrical terminal power distribution devices. Because both belong to the circuit breaker, and the molded case circuit breaker is mostly used for small-capacity switching.
Molded case circuit breaker
Molded case circuit breaker is known as MCCB. The main function of this circuit breaker is to provide protection functions for overload and short circuit in the low-voltage power distribution system and motor protection circuit. Because of its reliability and stability, it has become a very widely used product in industry.

Existing reviews of 16 amp 4 pole Miniature Circuit Breaker

Worked perfectly for my application.

I bought this miniature circuit breaker last week. I used it as a switch on the DC input side of my PV charge controller. The DIN rail is wide enough for installing a protector next to it. I am happy with this purchase. I will buy again from ATO.com.

This MCB is perfect for my applications.

This 16 amp 4 pole miniature circuit breaker can protect my solar controller from damage by disconnecting solar power panel until battery connection is made. Perfect for my applications. Very pleased with this order and I would buy more if I need.
