Sensitivity of Lexic Residual Current Devices

- Jul 16, 2018-

There are 3 types of Lexic Residual Current Devices according to the sensitivities:

●Type AC: sensitive to residual alternating currents;

Use: standard application;

●Type A-S: sensitive to residual alternating currents with DC components;

Use: special applications like rectifier bridge etc;

●Type Hpi: enhanced immunity to unwanted tripping in environments with disturbances, defects with DC components;

Use: special applications like DG sets, computers, printers, thyristors etc;
