In the housing (10) is arranged an insulating element (9) which encloses at least the part (62a) of the current rail (6a) which passes through the yoke (111a), and constitutes the seat for the current transformer (11a). One of the housing walls comprises the seat for the insulating element which is held in its position by its edge surfaces (91,94) locating against the side walls (101,102) of the housing, and/or against heel formations arranged in it. The current transformer (11a) is held in its position by guide heel formations (95a,97a) formed in the insulating element (9) which work in conjunction with recesses arranged in the current transformer yoke. - A support plate (14) for components rests on a support surface formed in the housing inner part, and on at least a beam (112a,113a) of insulating material in the current transformer. A cover fixes the support plate and the current transformer in their positions in the housing. |
