Havells X7 DHMYCSPM016 MCB (Miniature Circuit Breaker) 16A (White)

MCB stands for Miniature Circuit Breaker. It is a type of electrical switch that automatically shuts off the electrical power supply to a circuit when it detects an overload or short circuit. The purpose of an MCB is to protect electrical equipment and prevent electrical fires by interrupting the electrical current flow before the circuit becomes overheated or damaged. MCBs are typically used in homes, offices, and industrial settings to protect individual electrical circuits. They are installed in an electrical panel or distribution board and can be reset after they trip by simply turning the switch back on. MCBs are available in a range of current ratings and trip curves to accommodate different applications and electrical loads. They are also designed to provide protection against ground faults and other types of electrical faults, making them an important safety feature in any electrical system.

There are several types of MCBs, each designed for a specific application. Here are some of the most common types:

1. Type B: These MCBs are designed to protect against overcurrents caused by general-purpose loads such as lighting circuits and domestic appliances.
2. Type C: These MCBs are designed to protect against overcurrents caused by inductive loads such as motors, transformers, and fluorescent lighting.
3. Type D: These MCBs are designed to protect against overcurrents caused by high inrush current loads such as discharge lighting, switch mode power supplies, and X-ray machines.

It's important to choose the right type of MCB for your specific application to ensure optimal protection and performance.
