Current metering

For temporary or permanent monitoring of the load current, EFEN offers a current metering set, consisting of:
– a maximum ammeter
– a current transformer
– a current transformer fuse-link.

  • The combination of current transformer fuse-link and current transformer corresponds in all essential dimensions to DIN VDE 0636-201. It may be inserted into standard NH fuse-bases, NH fuse-rails and EFEN fuse-switches vertical design.
  • The electrical characteristics of the NH fuse-links correspond to VDE 0636/201 and IEC 60 269-2-1. The current transformer has two pairs of sockets, corresponding to the measuring ranges. As the no-load voltage at the measuring sockets is only 3 V, the current transformer can be used in open circuit condition. Corresponding to the current transformer, the ammeter has two scales.
  • Response time 8 minutes.
  • The overload protection covers 2 times the value of the measuring range.
