USAGE
GCK series switchgear is suitable for mining industry, 3 phase AC frequency 50Hz, rated voltage 380V to 600V, primary distribution of power system and secondary distribution or control equipment for asynchronous electric motor. It also suits train station, port, skyscraper; it is especially optimal for motor control system and on-site control devices of power plant, transformer substation, oil industry, chemical industry, metallurgy, machinery, light industrial assembly line. It can be connected with PC (Programmed Controller) or microprocessor to form automatic power supply and distribution control system if installed with suitable connection.
FEATURES
The main feature of control cabinet is that it can be arranged flexibly regards to different arrangement. Besides, the arrangement is able to be drawn out and be substituted shortly when it breakdowns. Same arrangement can be installed into any cabinet. For the purpose of safety precaution, there are ventilated in partition compartment and pressure relief valve on the top of cabinet due to release the high pressure gas when breakdown. This series is in compliance with GB7251:1 and IEC60439-1 standard.
