The present publication discloses a fuse unit for holding a fuse (6) and comprising a body part (1) and contact means (2, 4) for coupling a fuse (6) mounted in the fuse unit to an external circuit. According to the invention, the fuse unit comprises a slidable fuse carrier (5) compressive-force-exerting means (5) and locking means (7, 8), adapted to operate so that the slidable fuse carrier can be withdrawn into a rear position against the compressive-force-exerting means (7, 8) and respectively can be released from this rear position and that, in its released position, the slidable fuse carrier (3) is adapted to cooperate with the compressive-force- exerting means (5) so as to establish a contact pressure between the fuse (5) and the contact means (2, 4). The fuse unit according to the invention features easy replacement of the fuse and facilitates manual fuse replacement operation without tools. Moreover, the springed contact loading of the slidable fuse carrier (3) assures a sufficiently high contact pressure.
