The C Series is a range of high-performance 1,000 A transformer clamps. The round jaw shape and the uniformly-distributed winding guarantee accuracy and minimum phase difference.
It is equipped with an oscillating magnetic element adjustment system and a patented system for gradual assisted jaw opening.
Its Ø 52 mm clamping capacity allows current measurements on most conductors on CAT III 600 V industrial and tertiary installations.

When used with a multimeter with an mV AC range and good measurement resolution, this 4-calibre clamp allows measurement of leakage or differential currents starting at 1 mA.

Main features of the C173 model:

  • Output signal: AC voltage
  • Output / input ratio: 1 V / A AC, 100 mV / AAC, 10 mV / A AC, 1 mV / A AC,
  • Output via lead and isolated Ø 4 mm male plugs
