ZCT with Primary Conductor｜Fast & Accurate Ground Fault Detection for Industrial Power Safety

The Zero-Phase Current Transformer (ZCT) with integrated primary conductor is a next-generation solution for accurate ground fault protection. Unlike conventional ZCTs, this built-in design offers faster installation, higher detection precision, and simplified maintenance.
It’s ideal for power distribution systems in industrial plants, office buildings, and public infrastructure—reducing the risk of equipment damage and protecting personnel from electric shock hazards.
Hitachi Asia (Thailand) Co., Ltd., headquartered in Bangkok, supports industrial clients across Southeast Asia—including Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam.
