Leakage current tester - AC max 100A | HT77N
The HT77N is a leakage current tester that is used to accurately measure extremely low alternating current values. This device is primarily utilized to gauge leakage currents that causes residual current devices to trip on civil and industrial electrical installations. It is integrated with a low pass filter of 50/60Hz that enables the cutting off of harmonic parts. Several alarm thresholds with acoustic markings can be selected through the HT77N. This depends on the measured current values. The equipment is equipped with an automatic backlight sensor that is useful for testing in dark working areas. This leakage current tester is constructed in accordance to IEC/EN61010-1 standards and under CAT III 300 Volts.
