LV HRC signal detectors are used for remotely indicating that the LV HRC fuse links have been tripped. 3 different solutions are available:

• 3NX1021 signal detectors with signal detector link
  The LV HRC signal detectorsВ with signal detector link support monitoring of LV HRC fuse links with non-insulated grip lugs of sizesВ 000 toВ 4 at 10В A or more. The signal detector link is connected in parallel to the LV HRC fuse link. In the event of a fault, the LV HRC fuse links are released simultaneously with the LV HRC fuse detector link. A tripping pin switches a floating microswitch
• 3NX1024 signal detector top
  The signal detector top can be used with LV HRC fuse links, sizesВ 000, 00, 1 and 2, which are equipped with non-insulated grip lugs and have a front indicator or combination alarm. It is simply plugged into the grip lugs
• 5TT3170 fuse monitors
  If a fuse is tripped, the front indicator springs open and switches a floating microswitch. This solution should not be used for safety-related systems. For this purpose, we recommend our electronic fuse monitors.
