HT77 Clamp for AC TRMS leakage current measurements

HT77 TRMS clamp model is designed by using a special nucleus for measurement of very low current and is an essential instrument for leakage currents detection which are the typical problem about RCD' s tripping. It is also employed for measurements of first fault currents in medical rooms. HT77 was realised according to IEC/ EN61010-1 safety standard in CAT IV 600V and CAT III 600V for current and voltage measurements accordingly.
