Description

Hyosung’s ACB features eight setting ranges for optimum use on site. It also protects the high current devices by using GE, while the users are protected with ZCT. With two types of standardized external dimension, the design of the switchgear is optimal.

Features

Digitalized OCR for the first time domestically
Accurate measurement and operation enables speedy reactions to accidents
Eight types of settings fine-tuned for the user’s environment
GR not only protects devices but also safeguards human life using ZCT
