LS Electric EMPR Current Transformers, ZCT and MCT

LS Electric EMPR Current Transformers, ZCT and MCT

LS Electric current transformers (3CT, 2CT, 1CT), zero-phase current transformers (ZCT) and IMC-III MCT units for use with GMP, DMPi, IMP, MMP and IMC-III motor protection relays.

Key features

  • 3CT, 2CT (DCT) and 1CT (SCT) transformers extend EMPRs to 50-600 A motors with 5 A secondary

  • LZT (I) current-output ZCTs (200 mA/0.1 mA) dedicated to IMC-III
  • MCT 1CT units with 2 m or 4 m cable for IMC-III (3 per controller)
  • EMPR can be mounted on top of LS CTs
