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
Through-hole current transformers (PIN version) Description With through-hole current transformers, the primary conductor on the construction side is inserted through the current transformer opening in the housing. The through-hole opening is oriented to the primary current strength. Wound current transformers have a primary winding and a secondary winding. Both windings are applied to the closed ring core and separated from each other by insulation. This principle is predominantly used for small primary currents. Advantages PIN – Connection according to UL 94 V0 Through-hole current transformers for direct conductor routing Design as wound transformer for small currents Ring band cores made of high-quality silicon iron Measurement in the lower frequency range 16 2/3 to 400Hz High core output power and high-quality insulation Electrically isolated primary and secondary circuits easy-to-install designs Variable connections e.g. terminals, plugs, flat plugs, stranded wires or PCB mounting Versatile housing options with different through-hole openings Technical data According to: EN/IEC 61869-1/2 Rated primary current: 1 – 50 A Frequency range: 50 – 400 Hz Rated primary current: 1 – 50 A Type 1 3 5 10 25 50 2 windings through-hole transformer Primary current [A] IPN 1 3 5 10 25 50 Max.
