DIAMOND MCB

Product Description

A Miniature Circuit Breaker (MCB) is an essential electrical safety device used to protect electrical circuits from damage due to overloads and short circuits. The key specifications of an MCB include:

1. Rated Current The maximum current the MCB can carry continuously without tripping. Common ratings range from 1A to 100A.

2. Breaking Capacity The maximum fault current an MCB can safely interrupt without causing damage. Typically ranges from 3kA to 10kA or higher, depending on the model.

3. Trip Characteristics MCBs are classified based on their time-current characteristics. Common types are:

- Type B Trips between 3 to 5 times the rated current, suitable for residential loads.

- Type C Trips between 5 to 10 times the rated current, ideal for commercial or industrial loads with moderate inrush currents.

- Type D Trips between 10 to 20 times the rated current, designed for high inrush current applications.

4. Poles MCBs are available in single, double, triple, and four-pole versions to protect different types of electrical systems.

5. Voltage Rating Typically designed for 230V or 400V systems, MCBs ensure safe operation within these voltage levels.

6. Standards Compliance MCBs meet international standards like IEC 60898, ensuring reliable and safe performance in various environments.

MCBs offer reliable protection, compact design, and are essential for modern electrical systems.
