PRODUCT PARAMETERS

SELECTION GUIDE

1. How to Calculate the Number of Amperes?

Formula: Current (A) = Power (W) / Voltage (V) . Calculate the required current based on the power of your electrical appliances.

2. How to Choose the Pole Number?

•  1P : Single pole, 1 module (18mm wide), for 230V live wire only (no neutral).

•  1P+N : 1 module (18mm wide), for 230V live + neutral.

•  2P : 2 modules (36mm wide), for 230V live + neutral.

•  3P : 3 modules (54mm wide), for 400V 3-phase live wires (this product).

•  4P : 4 modules (72mm wide), for 400V 3-phase + neutral.

3. How to Choose Ampere Rating?

Match the breaker rating to the wire and appliance power to avoid tripping or terminal overheating. Refer to the table below:

4. Can I Choose a Larger One?

No.  Always select a breaker with a current rating smaller than the wire's maximum carrying capacity . For example, a 2.5mm² BV wire can withstand a maximum of 26A, so a 25A or lower breaker must be selected.
