In recent years the use of loads with power electronics has become widespread. Type B residual current protection is the only protection that safeguards people and loads against AC, DC and AC/DC leakages. Type A and AC residual current protection devices do not detect continuous residual currents, which are so common in loads such as variable speed drives, UPS's, EV chargers, photovoltaic installations, etc.
