Passive Current Transformers Series IN-D
Differential current transformer Description The residual current transformer makes it possible to measure the residual current on single-phase or three-phase supply cables or individual lines. Both current-carrying conductors (forward and return conductors) are fed through the current opening of the current transformer. The current is measured by comparing the forward and return conductors. Any deviation is displayed at the output of the residual current transformer. Due to the use of highly permeable materials, a typical current deviation from 10 mA is given. The large opening allows the supply lines to pass directly through over a wide area, with the exception of the protective conductor. Due to the high current sensitivity, evaluation in several stages is possible: stage 1: Notice of a malfunction stage 2: Alarm stage 3: Switching off Advantages The measurement from 25 to 400 Hz Nanocrystalline core Transformer for measuring differential current High-quality UL-listed insulating materials (e.g., UL94VO) safe, electrically isolated primary and secondary circuits Robust housing designs (for horizontal/vertical mounting) Variable connections Wide range of housings with various push-through openings Residual current range 2 – 50 A Typical Applications Industry, Renewable energy sources, Metrology and testing techniquesEnergy, automation and building technology Technical data Type 2 4 8 29 30 40 30 40 50 Housing A Housing B Housing C Primary current [A] IPN 0,1 – 1 0,1 – 2 0,1 – 4 0,1 – 10 0,1 – 10 0,1 – 10 0,1 – 10 0,1 – 10 0,1 – 10 Max.

Passive Current transformer Series IE (Pin Version)
Bushing-type current transformers (PIN version) Description 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. Advantages PIN-Connection according to UL 94 V0 Bushing-type current transformers for direct conductor feedthrough Wound primary type current transformer, version for small currents Toroidal cores made of high-quality silicon-iron Measurement in the low-frequency range 16 2/3 to -400Hz High core output power and high-quality insulation (UL) circuits primaires et secondaires séparés électriquement des formes faciles à monter Variable connections, e.g. clamps, plugs, flat-cable plugs, flexible stranded wire or print mounting Wide range of housings with various push-through openings Technical specification Technical Data According to: EN/IEC 61869-1/2 Primary rated current: 1 – 50 A Frequency range: 50 – 400 Hz Type 1 3 5 10 25 50 2 Windings Through transformer Primary rated current [A] IPN 1 3 5 10 25 50 Max.
