Selection Guide

1. How to Calculate the Number of Amperes?

Formula: Current (A) = Power (W) / Voltage (V)

Calculate the required rated current according to the power of electrical appliances and voltage.

2. How to Choose the Pole Number?

3. How to Choose Ampere Rating?

The circuit breaker must be matched with the wire and electrical power to avoid tripping or terminal burning. Refer to the table below for wire selection:

4. Can I Choose a Larger One?

No . When selecting a circuit breaker, the rated current must be smaller than the wire's withstand current.

Example: A BV2.5mm² wire can withstand a maximum current of 26A, so a circuit breaker of 25A or less must be selected.
