Schneider Korea Sanhe EOCRFEZ-H4AF7AQ digital display motor protector

Schneider Korea Sanhe EOCRFEZ-H4AF7AQ digital display motor protector â–  Three integrated assembled current transformers â–  Over current, under current, phase loss, phase imbalance, reverse phase, stall protection Schneider Korea 3 and EOCRFEZ-H4AF7AQ Explicit motor protector



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.

MCU-based products ■ Three integrated assembled current transformers ■ Over current, under current, phase loss, phase imbalance, reverse phase, stall protection ■ Digital meter and trip cause display ■ Trip “time-current” characteristics selectable ■ Start delay and trip action delay time are independently set to 3EZ, also added ground protection to FEZ, and added ground protection
