Detailed Product Description

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
10 mA ,
30mA,100mA,300mA or 500mA.
