Product Name : Low Voltage
Product Description

Metal-Enclosed Low Voltage Switchgears

Besides fixed type, Horng Yu Electric Co., Ltd.(HYEC) also devotes to manufacturing withdrawable Low Voltage Switchgear and Controlling Device (Below called IS-06 or drawer type) for 3-phase power system in the maximum of rated voltage AC 690V and rated current 6300A function as power transmission and distribution which also features control, monitoring, and protection to circuit.

Drawer type is in conformity of standard IEC 61439. And it has been fully tested by International Laboratory Accreditation Cooperation (ILAC) and Taiwan Electric Research & Testing Center (TERTEC). Withdrawable unit is equipped with comprehensive and reliable device to prevent false operation. Drawer type is the best choice for power supply which provides safer power usage environment. HYEC LV Switchgear is your first choice used in a range of applications like industrial, institutional, critical power, and commercial. If you have any question or need help, please feel free to contact us.
