30mA RCD RCCB General:
This is a 30mA RCD type B RCCB residual Earth Leakage Current breaker，It is suitable for circuits with rated currents of 10A, 16A, 25A, 32A, 40A, 63A.
In addition to ordinary alternating current, 30mA RCD RCCB can also detect high-frequency alternating current and pure DC leakage current to ground.
Reducing the risk of fire and/or electric shock by automatically disconnecting the power supply depends on choosing the correct type of RCCB.
