Sanhe EOCR Co., Ltd. is Korea's largest manufacturer of motor protectors. The company was founded in 1981 by Dr. Jin Renxi (CEO of Schneider Electric Group Korea).
In 2001, in order to develop the company into a global, strategic enterprise, he joined the Schneider Electric Group of France.
EOCR's main products are electronic motor protection relays, electronic overcurrent relays, electronic undercurrent relays, electronic undervoltage relays, other protection and monitoring devices, and current transformers.
