Core Explanation (Technology+Market Value)

G

Low-voltage sw itchgear

Define the voltage level as 0.4kV low voltage,suitable for the power distribution and control requirements at the end of the low voltage distribution network, different from medium and high voltage switchgear

C

Drawer type/Motor control

Core structural features:The components are integrated into the withdraw able drawer,while also taking into account the motor control function,adapting to the distribution and control scenarios of industrial motor groups.

K

open structure/Withdrawable

Emphasize that the cabinet adopts a modular pull-out design,and the draw ers can be pulled out of the cabinet as awhole, Realize uninterrupted replacement during maintenance to improve pow er supply reliability

□

Main circuit scheme number
