Provided is an electrical fault protection device comprising: a housing having supply terminals and output terminals; internal conductors passing between the supply terminals and the output terminals via at least one fault protector relay contact; a fault protector operably connected to the at least one fault protector relay contact and responsive to a fault to open the at least one fault protector relay contact; an aperture defined in the housing so as to facilitate the feeding of at least two external supply conductors through the housing; a contactor driven from the output terminals, the contactor incorporating at least one normally open contact corresponding to a respective external supply conductor, wherein a current rating of the at least one contactor contact is substantially greater than a current rating of each of the at least one fault protector relay contact. |
