**MCB 0.5 Ampere: How Many Watts?**

### What is MCB?

**MCB** stands for **Miniature Circuit Breaker**, a type of electrical switch that automatically breaks the electrical circuit when there is an overload or short circuit. MCBs are designed to protect electrical circuits from damage caused by excessive current.

### Understanding MCB Ratings

MCB ratings are typically expressed in amperes (A) and are used to indicate the maximum current that an MCB can handle before tripping. In this case, we're looking at an MCB with a rating of 0.5 amperes.

### Calculating Watts from Amperes

To calculate the watts (W) from amperes (A), we need to know the voltage (V) of the circuit. The formula to calculate watts is:

**Watts (W) = Volts (V) x Amperes (A)**

For a standard household voltage of 230V, we can calculate the watts as follows:

**Watts (W) = 230V x 0.5A = 115W**

### So, How Many Watts?

Based on the calculation above, an MCB with a rating of 0.5 amperes can handle a maximum load of **115 watts**. This means that if you're using an electrical device that consumes more than 115 watts, the MCB will trip to prevent damage to the circuit.

### Conclusion

In conclusion, an MCB with a rating of 0.5 amperes can handle a maximum load of 115 watts. It's essential to ensure that you don't exceed this limit to prevent electrical accidents and damage to your devices. Always check the power rating of your devices and the capacity of your MCB to ensure safe and efficient use of electricity.
