RD2 residual current relays
Residual current relays with external toroidal transformer can detect leakage currents.
Through minidip it is possible to set sensitivity and intervention time. RD2 residual
current relays are designed to be used with external toroid belonging to TR family –
see the dedicated section in page 2/134.
