Yes.


More details:

Different country has different value of power system but same structure: such as TN-S(Single phase), TN-C(three phase), TN-S(three phase) etc.


We used the valide value to describe as  Single phase value/ three phase value.

In China/Europe, it's normally 220/380VAC;and, in Malysia/USA, it's 240/415V.


According to the standard, Uc>Un*1.15;

let's  take T2-20/2P as an example,


T2-20/2P, Uc=320VAC,   220*1.15=253, 240*1.15=276.

So, CHENZHU's SPD could fully used for 220/380 V AC or 240/415V AC system.
