The invention relates to a fuse combination unit (1), comprising a housing (2) and an operating rocker (30) for receiving a fuse cartridge (20), or a fuse plug (10) which contains a recessed area for a fuse cartridge. The operating rocker (30) is mounted in the housing (2) so that it can be pivoted between an on-position and an off-position and a sprung-loaded contact device (40) comprising a contact element (41) is located in the housing (2), in such a way that when the operating rocker is in the on-position, the contact element (41) makes contact with the fuse cartridge via a counter-contact whilst being subjected to a potential load. The operating rocker (30) and/or the contact device (40) have at least one contact-guide element (45) which maintains the contact element (41) at a defined, relative distance from the counter-contact (51) in accordance with the position of the operating rocker (30), whereby the distance is only substantially zero when the operating rocker (30) is in the on-position, so that the contacts do not abrade each other (41, 51) during the displacement of said operating rocker (30). The invention also relates to a fuse plug, comprising a corresponding contact-guide element. |
