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.
 

Current low / medium: 1 mA - 1.2 A / 0.01 A - 12 A / 0.1 A - 120 A / 1 A - 1,200 A
Transformation ratio (input/output): 1 A / 1 V 10 A / 1 V 100 A / 1 V 1,000 A / 1 V
Typical accuracy: ≤ 0.7 % ≤ 0.5 % ≤ 0.3 % ≤ 0.2 %
