Digital Overcurrent Relay

Model No: EOCR-SSD

Digital Overcurrent Relay EOCR-SSD finds usage for detecting the flow of current, when it gets exceeded from a particular level. Only a single operated current is used in this type of element without the usage of any voltage coil that is required for building the protective relay. It is capable of withstanding diverse industrial conditions to be used in the different engineering applications.
