57.904.5555.0

The 57.904.5555.0 is a 2-position 1-level gray DIN rail (top hat rail)/G-rail mounting Fuse Terminal Block with screw connection. The WK 4/THSi 5 LED 24 U fuse block is thermoplastic insulator housing. The fuse block of this type has a flip top disconnect lever. The hinged lever has latch points both in the open and in the closed state and can be sealed. The voltage range is determined by the built-in LED display. Depending on the application and the installation method, the circumstances for increased temperature must be checked in the closed fuse holders. Higher ambient temperatures are an additional load for the fuse inserts. Therefore, the reduction of the rated current must be considered accordingly in these applications.
