S24 Class B RCDs for advanced applications

S24 Class B RCDs are intended for installations where residual currents can include AC, pulsating DC and smooth DC components. This makes them suitable for more demanding technical applications than Class AC or Class A devices.

They are recommended for circuits associated with frequency converters, EV charging, photovoltaic equipment and other electronics that may create DC leakage.

Class: B class for AC, pulsating DC and smooth DC residual currents.
Series: S24 range for DIN-rail modular boards.
Formats: 4P options for three-phase technical applications.
Use: inverters, EV charging, PV and advanced electronics.

This specific positioning prevents overlap with Class A, Class AC and super-immunised differential categories.
