Schneider Electric DOM RCD, 63A, 2 Pole, 300mA

These RCCDs reliably isolate circuits that have damaged insulation and the electrical current is circulating through earth. They equally protect people from electrocution while being accidently exposed to direct and indirect contact with live conductors. These RCCDs function on an electro-mechanical principle by comparing the current entering through the phase conductors with it going out through the neutral conductor. When certain differences between the two currents are detected (the insulation level has dropped down and dangerous earth current starts to flow) the earth-leakage device trips. The Residual Current Circuit Breaker (RCCB) ensures all installations against earth leakage damage. They meet international standard requirements IEC61008 & IEC60364. Can be used in all earth systems: TT, TNS, TNC-S.
