This series Residual Current Circuit Beaker have a residual current operated electromechanical release which operates without 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 a threshold of 30mA, 100mA , 300mA. RCCB is not suitable for use on DC
pulse system. It conforms with the standards of IEC60947.
