6300A 400 Hz Low Voltage Switchgear

Electrical Low Voltage Switch Cabinet GCK

Electrical Low Voltage Switch Cabinet GCK  features
Electrical Low Voltage Switch Cabinet GCK is a complete power distribution device for 3.6~24kV,3-phase AC 50Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc., so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with3AH5 from Siemens domestic ZN65A,and VB2 from GE, etc., it is truly a power distribution device with good performance. In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.
