Abstract (en)

[origin: EP0921539A2] A low-voltage contact for high- and very high-intensity currents, particularly for electric transformers, comprising a body (2) made of aluminum and/or alloys thereof which has a substantially constant transverse cross-section and a length which is a function of the intensity of the current that affects the low-voltage contact. <IMAGE>
