Abstract:
A fused switch unit (10) having two connecting contacts (60, 70) into which a fuse holder (20) can be inserted in order to hold a fuse link (30, 35) with a head contact (31) and a foot contact (32), in which case a first connecting contact (60) of the fused switch unit (10) can be connected via a controllable interruption contact (80) and by means of a bridging element (81) to a first (31) of the contacts (31, 32) of the fuse link (30), and in which the fuse holder (20) or the fused switch unit (10) has a fuse state indicating device (40) with two contacts (42, 43) for an electrical connection for the connecting contacts (60, 70) of the fused switch unit (10), whereina first contact (42) of the fuse state indicating device (40) can be connected via an electrically conductive connection (91, 92, 82) directly and exclusively to the bridging element (81), and a second contact (43) of the fuse state indicating device (40) can be connected directly via an electrically conductive connection (50, 51, 52, 53, 71) to the second connecting contact (70) of the fused switch unit (10).
