Different Types of MCB
MCB are of different types is suitable for specific load characteristics.
Type B
Ideal for resistive loads such as lighting and heating in residential (or) household applications.
Type C
Suitable for commercial and industrial loads with moderate inrush currents
Eg: Small motors & fluorescent lighting
Type D
Designed for heavy-duty industrial machinery with high inrush currents
Eg: large motors and transformers.
Type K
Optimized for inductive loads like
1). Motors and
2). Transformers
that produce short-duration inrush currents.
Type Z
Intended for sensitive (or) electronic equipment that requiring accurate overcurrent protection.
Eg: semiconductor devices and preferred for sensitive electronic circuits.
Selecting the correct MCB assures that
1). Proper protection,
2). Safety and
3). Reliability of the electrical system.
