SOCOMEC current transformers provide a standard current to the secondary proportional to the primary current, which is adapted to the related device's rating. Standard version features detachable terminal covers and double terminals, which allow short-circuiting of the secondary with no extra risk.
Mounting is done with two screw-on metal brackets or in a few instances they have a clip-on DIN rail mounting. Either screws or fast-on terminals are used for making connections. Standard accuracy class is 0.5, and for higher necessary power, it can be 1 or 3. The dielectric quality is 3 kV - 50 Hz - 1 mn and operating frequency is 50-60 Hz. They have a permanent overload of 1.2 In.
