Can we go for type B MCB for lighting & small power load?
The differences between the tripping curves are as follows:
B Curve: Overcurrent protection for electronic equipment, generators and long cables. Magnetic release operates between 3.2 and 4.8 times the Ampere rating.
C curve: Overcurrent protection for general applications. Magnetic release operates between 7 and 10 times the Ampere rating.
D curve: Overcurrent protection for loads with high inrush currents (motors, transformers). Magnetic release operates between 10 and 14 times ampere rating.
It is advisable to use a Curve C MCB for lighting applications instead of Curve B MCB to avoid nuisance tripping. As illustrated above, Curve B MCBs are more sensitive to faults..
