600 Volt Class Current Transformers

Wound Primary/Auxiliary Indoor


  • High accuracy at low currents
  • 4 kV primary to secondary isolation (wound primaries)
  • Models are available for metering and relaying applications
  • Some models have integral mounting feet or can be supplied with mounting brackets
  • Voltage Class: 600V
  • BIL Rating: 10kV(wound primaries)
  • Primary Current: 5 to 50 A
  • UL recognized – file number E93779
  • Manufactured to meet the requirements of IEEE C57.13 Voltage Class: 600 V


Auxiliary current transformers are designed for connection in the secondary circuit of a main current transformer to change the effective ratio on meters or relays. Wound primary CT’s which are rated for the system voltage are available for primary currents up to 50 amperes. We also offer summation CT’s for summing up to six secondaries.
