Why we need a MCB 

An MCB is an electrical switch which operates automatically and intelligently. Miniature circuit breakers or MCB are designed to prevent damage to an electrical circuit as a result of excess current. MCBs are designed to trip in the condition of an overload or short circuit to protect against electrical faults and equipment failure.

Types of MCB and how to select MCB -
the very first thing which is important for us to know about the types of MCB trip curves which hepls to understand  that what type MCB has to be used for different appliances for the correct electrical system.  But before that, first understand what a trip curve means. Trip curves are nothing but the maximum current that a particular MCB can withstand. Once the thismaximum  current loading is breached, the circuit automatically cuts off.

There are  six different types of MCB -  A, B, C, D, K and Z. -

• Type A trips off the circuit when the current exceeds 2-3 times the actual current rating. as this type is highly sensitive to short circuit, it is better suited for semiconductor devices.
• Next, Type B, which trips off when the current flow is 3-5 times the actual current rating and it is preferred for cable protection.
• Third is  Type C. Type C MCB trips off when the flow of current is 5-10 times more than normal.mostly used with domestic appliances where current load is medium
• Type D MCB has a high resistance as they can withstand up to 10-20 times the current rate. If you are looking for circuit breakers for devices with high starting current load like a motor, then type D is the ideal choice.
• The type K MCB withstands up to 8-12 times the initial charge and thus can be used for bulky load devices.
