1322613 Fusible cut-outs APLICACIONES ELECTRICO INDUSTRIALES CRADY SA 19 April 1971 [3 Nov 1970] 25186/71 Heading H2G Flanges 3 on the lid 1 of a live fuse holder shield the resilient forked contacts 4 while the lid is being put on or taken off. A cartridge fuse (not shown) is held in the lid and a parallel circuit comprising a resistor 7 and a lamp 8 indicate when the fuse has blown. The lamp 8 lights when a potential above a threshold value appears across it. A flat plate 10 on the end of the terminal screw holds the wire, and resilient plates 9 hold the fork contacts 4 against the terminal block 5. At least the inner resilient plate 9 is conducting. |
