  • Series IE modular

    Through current transformers (module-based)

    Series IE modular
    • Primary rated current: 500 - 2500 A
    • Umgebungstemperatur: -25... +70 °C
    • Frequency range: 50... -400 Hz

    In the case of bushing-type current transformers, the customer’s primary wire is pushed
    through the current transformer opening in the housing. The push-through opening depends
    on the size of the primary current.
    Wound primary type current transformers have a primary winding and a secondary winding.
    Both windings are applied on the closed toroidal core and are isolated from each other by
    insulation. This principle applies mainly where primary currents are small. Low-voltage current
    transformers for the proportional transformation of large currents to directly measurable
    smaller current values.

    According to: EN/IEC 61869-1/2
    Primary rated current: 500, 1000, 2500 A
    Frequency range: 50 - 400 Hz

    Applications:



    • Industry

    • Renewable energy sources

    • Railway engineering

    • Energy, automation and building technology

  • Series WKO-2C-B

    Double core technology closed-loop current transformers for railway engineering

    Series WKO-2C-B
    • Primary rated current: 500 - 2000 A
    • Messbereich: 0...3000 A
    • Frequency range: 120000 Hz

    The current transducer WKO-2C-B with hall effect elements and double-core  technology    has an extended frequency response up to 150 kHz and an accurate phase response. The WKO-2C-B guarantees an increased current measurement accuracy better than 0.5% in the whole frequency range: DC to 150 kHz.


    A completely redesigned electronics ensures that the new C/L current transducer has better drift compensation and an extended temperature range from -40°C to 85°C.


    Modular design


    The current transformer has a modular design which allows a variety of mounting options. The cost-effective basic model consists of a housing with screw terminals, bushing for cable and holes for fixing. Optionally, the transducers are available with mounting kit for busbars, molex connectors and feets for horizontal or vertical mounting.
