Product Description



The GREWIN CTC series of clamp-on current transformers are designed for fast and easy installation. The clamp-on core design permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken offline and disconnected for CT installation. This method permits a safer, easy and portable current measurement.

High precision standard mini clamp on current transformer ct
Features Low cost. 6 standard size Clamp-on core design,safer,easier installation, portable Both Silicon Steel & Nickel Alloy cores available Applications Silicon Steel cores provide moderate accuracy and lower cost for appropriate current measurement current Nickel Alloy cores are suitable for applications that require the highest accuracy with minimal phase angle error. Applications would include electric power quality monitoring devices Specifications Case material:Polypropylene resin Voltage rank:600Vac(isolated condition), 30Vac(bareness condition) High Potential:2500Volts/min Dielectric Resistance:1000MOhms @ 500 Vdc Operating Temperature:-25ºC to +70ºC Frequency:50 /60 Hz RoHS compliant CE-approvedOur main product are miniature voltage transformer ,miniature current transformer ,instrument current transformer , clamp on ccurrent transformer ,split core current transformer ,three phase current transformer ,zero-flux current transformer
