IGR-32

IGR_earth leakage current breaker

After separating the resistive leakage current (Igr) causing actual electric shock and electric fire and the capacitive leakage current (Igc) due to the capacitance between the wire and the ground or the harmonic current generated from the power supply of the digital equipment,

A new concept patented IGR leakage current breaker (green trip curve) trips sensitively (18mA) to the actual leakage current (Igr), however

If the lightning strikes too much or if the leakage current (Igc) of the reactive component is large due to the harmonic current, it will not trip unnecessarily (90mA).

This was patented in Korea as 10-2008-0093169 (2008-10-21).
