The RCD 30mA Type B is a residual current device linked to a smart reclosing motor, which makes it possible to safely reclose the corresponding RCCB. It’s designed to detect and disconnect all types of earth leakage faults, including smooth DC and high-frequency AC residual currents. Suitable for use with EV chargers, variable speed drives, and solar PV systems, this RCD provides enhanced protection where conventional Type A or AC devices are insufficient. It delivers reliable personal protection against electric shock while meeting the safety requirements of modern electrical installations.
