Q3. Which type MCBs suitable for halogen lamps?
Ans. 
Type B MCBs are suitable for halogen lamps.
• Type B MCBs have a characteristic curve that allows for a short-term surge in current, which is common in halogen lamps.

• Type C and D MCBs may trip too quickly and cause nuisance tripping.

• It is important to check the wattage and voltage of the halogen lamp to ensure the correct MCB is selected.

• Examples of Type B MCBs include Schneider Electric Acti 9 iK60N and ABB S 200 series.
