Thanks Ricbevi, I am in Santiago del Estero and I already looked for the market and for E.Bay but I do not locate it, ask for a replacement according to its data but there is no one that handles both the amps and its voltage. A colleague suggested that I try to put them in parallel example two of 10A x 500v would be 1 of 20A of 500v as I need but I don't know how to do it.-
