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.
