4P Type A 30mA

interruttore differenziale puro, Clem Brescia
RCCBs 4P GO range are suitable to detect earth faults’ currents. In case the installation requires also protection from eventual overload and short-circuits, the RCCBs must be installed in series with MCBs or with fuses.
Type A RCCBs grant protection in presence of faults current of both sinusoidal alternate and pulsating type. They are therefore recommended to protect installations where the connectable electric devices have electronic rectifiers or electronic circuits regulating the current wave.
RCCBs’ functioning is independent from line voltage and the mechanism is trip-free, meaning that RCCBs can also trip when the lever is held on close position
All products can be power supplied from both the top and the bottom terminals. Furthermore “cage” type terminals facilitate connection both through conductors (up to 35mm² rigid and 25mm² flexible) and through busbars (both pin or fork types).
