The document describes the features and characteristics of fuse terminals with built-in safety fuse links offered by IMO. The terminals have a moving type hinged carrier that provides a specially designed space for installing cartridge type glass fuses of size Ø5x20 or Ø5x25, along with a spare fuse. In ERF 3M and ERF3 type products, the fuse can be engaged or disengaged by moving or replacing the carrier, respectively. Marking/identification using tags is possible on both the terminal and fuse carrier. A specially designed built-in circuit provides light indication in the event of fuse blow out.
