RCMX100 Residual Current Relay

RCMX100 Residual Current Relay

Type A residual current monitor with digital display, used for leakage protection of pure AC permanent
Description
RCMX100 Series Introduction:
RCMX100 series residual current monitoring relay is an electrical safety preventive monitoring product with digital display. It is matched with CT and KCT precision residual current transformers and is used in AC grounded power grids. RCMX100 can accurately measure the residual current value of the power grid to the ground and judge the fault branch, and can transmit the residual current value to the host computer through the RS485 communication interface. One RCMX100 residual current monitoring relay can support 1 residual current monitoring. The product has the characteristics of strong anti-interference ability, high detection accuracy, and flexible networking.
