RCCB's residual current device provides isolation, switching and earth leakage protection for electrical circuits

RCCB's residual current device provides isolation, switching, and earth leakage protection for electrical circuits. It has a residual current-operated electromechanicalrelease which operates without any auxiliary supply source to open a circuitautomatically in case of an earth leakage fault between the phase and earthgreater than or equal to a threshold of 10mA, 30mA, 100mA, 300mA, or 500mA.
