Positive Contact Indication:

mechanical indicator, appearing on the front face of the RCCB, linked to the contacts shows the positive opening of all poles,
red = contacts closed
green = contacts open

Earth Fault Indicator:

mechanical indicator appearing on the front face of the RCCB to differentiate between tripping and off position
yellow - tripped

Nuisance tripping:

all the RCCBs are protected against transient voltages (lightning, line disturbances) and transient currents (from high capacitive circuits).
