Miniature Circuit Breakers (MCBs) are essential components of modern electrical systems, A Miniature Circuit Breaker (MCB) is a type of circuit breaker that is designed to protect low-voltage electrical circuits. It consists of a switch that automatically trips and cuts off the power supply when an overload or short circuit is detected. This helps to prevent damage to the electrical circuit and equipment.

There are three types of MCBs: Type B, Type C, and Type D (B-type MCBs are typically used in residential and light commercial applications, C-type MCBs are commonly used in commercial and industrial applications where the load current is predominantly resistive, D-type MCBs are typically used in heavy industrial applications where the load current includes many inductive components or motors). The type of MCB you need depends on the type of load that you want to protect.

Changan Electric provides a series of several types of miniature circuit breakers with different breaking capacities. You can check the MCB classification for more information.
