RCM-RD-2 High Performance Dc Digital Control Earth Leakage Relay RCM-RD-2 High Performanc
Description
Residual Current Monitor is an essential device to monitor and safeguard electrical equipment. It serves as a reliable safety measure for electrical systems, as it detects residual current in a circuit and promptly shuts off the power supply when the residual current surpasses a predetermined threshold value. This automatic shutdown protects both electrical equipment and personnel from potential electric shocks. RCM is commonly used in electrical systems in residential, industrial and commercial buildings to ensure the safe operation of electrical equipment.
