The NID RCCB~S residual current devices provide the functions of isolation, switching
and
earth leakage protection of electrical circuits. They have a residual current operated electromechanical release which operates
with-
out any auxiliary source of supply to open a circuit automatically in the case of
an earth
leakage fault between phase and earth greater than or equal to threshold of
Leakage current: 10 mA , 30mA,100mA,300mA or 500mA.
Rated current:16A,20A,25A,32A,40A,63A
Pole: 2P , 4P
