UL 943 inverse time trip curve, Inverse time detection circuit protects people while also reducing the probability of nuisance tripping
DFT (Discrete Fourier Transform) filtering algorithm eliminates nuisance trips due to harmonics
Minimum trip time < 20 msec reduces the risk of ventricular fibrillation for leakage current of 250 mA and above
Fixed 6 mA (UL 943) or 20 mA (UL 943C) trip level UL Listed GFCI and Special-Purpose GFCI personnel protection for industrial and commercial loads up to 60 A
Two-stage ground monitor with Zener termination that meets UL 943C, CSA M421
Flexible configuration selectable manual reset or autoreset for brownout, power up, and ground monitor interruptions to fit plant safety protocols
Auxiliary contact alerts your SCADA system if the Shock Block is energized or tripped
Automatic self-test the Shock Block will continuously test itself and will trip if there is an internal failure
GFCI Class A, C, D and EGFPD options in one series simplified planning and operator familiarity for multiple applications/requirements
