B-type residual current devices are suited for use as protection in applications with both alternating and direct fault currents where traditional A-type devices do not provide protection. Such applications include, e.g. EV charging, solar power application inverters, and frequency converters. SI-type (Super Immunity) residual current devices are used in applications where continuity of operation is of the utmost importance. These products offer high performance in environments presenting high-frequency current spikes or challenging external conditions (dust, salt). EV versions designed for EV charging applications.
