Function

SOCOMEC current transformers deliver to the secondary a standard current proportional to the primary current and adapted to the rating of the associated device. They are equipped as standard with removable terminal covers and double terminals allowing the secondary to be short-circuited without any risk. They are mounted using two screw-on metal brackets or, in certain cases, by a clip-on DINrail fastener. The connections are made by screws or by fast-on terminals.

  • Accuracy class: 0.2s – 0.5 or 1.
  • Dielectric quality: 3 kV – 50 Hz – 1 min.
  • Operating frequency: 50 – 60 Hz.
  • Permanent overload: 1.2 In.
  • Insulation class: E (120 °C).
Advantages
An adapted accuracy class
  • In order to get the best of your DIRIS multifunction meters and COUNTIS energy meters, we can provide current transformers with the following accuracy classes: 0.2s; 0.5; 1 or 3.
A wide range of ratings and dimensions
  • Your measurement process can be optimised whatever your needs in terms of ratings, space requirements, conductor sizing or accuracy class.
  • A wide range of combinations are available in our standard range with specific versions available on request (other ratios, tropicalisation and specific frequency, class or burden).
Quick and easy to mount
  • Our current transformers are adapted to any type of mounting: edgewise or flat mounting, DIN-rail or back-plate mounting.
  • Implementation is easy and rapid.
