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
