The two module, double pole RCDs provide earth
fault current protection for residential and light
Available with a choice of 40, 63 or 80A rating,
and choice of 30 or 100mA sensitivity.
All BG RCDs are the common Type AC, suitable
for situations where there are residual sinusoidal
The Time Delayed RCD is used typically when two
RCDs are installed in series, and the time delayed
RCD enables discrimination, i.e. in the event of
a fault only the ‘upstream’ RCD should trip.
All RCDs have a positive contact status indicator,
i.e. when green window is visible this indicates
that there is a 4mm contact gap.
