Abstract

The present invention relates to a start system ( 1 ) comprising a plurality of electrical apparatuses ( 3, 5 ) each comprising an insulating casing ( 7, 9 ), secured to each other and having an alignment along a first extension direction (D 1 ). The plurality of electrical apparatuses ( 3, 5 ) is intended to be brought on a plurality of securing rails ( 13, 15 ) extending along a second extension direction (D 2 ) transversal to the first extension direction (D 1 ). A first electrical apparatus ( 3 ) comprises a removable mounting device ( 21 ) including a primary movable mounting element ( 17 ), the mounting device ( 21 ) forming a primary housing ( 35 ) in which a portion ( 13 a ) of a first rail ( 13 ) is able to be inserted. A second electrical apparatus ( 5 ) comprises a secondary mounting element ( 19 ), the secondary mounting element ( 19 ) forming, with the insulating casing ( 9 ) of the second electrical apparatus ( 5 ) a secondary housing ( 81 ) in which is able to be inserted a portion ( 15 a ) of a second rail ( 15 ).

First claim
