Kyn28A-12 removable AC metal-clad switchgear
KYN28A-12(Z) removable AC metal-clad switchgear (short for panel as below) is a new product, designed and developed by Zeen Electric, based on the introduction of advanced foreign design and manufacturing technology. It will be a substitute for old fashioned metal-enclosed switchgear, such as KYN-12, JYN-12, GFC-12, etc. The panel applies to 3.6~12kV 3 phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It can be arranged for single bus bar, single bus bar sectionlizing system or double bus bar. It accords with IEC62271-200 AC Metal Enclosed Switch and Control Equipment above 1kV and below 52kV IEC60694 Standard Common Clauses for HV Switchgear, DIN. VDE AC Switchgear at Rated Voltage Above 1kV, GB3906 3~35kV AC Metal Enclosed Switchgear and so on. It has perfect and reliable prevention function against misoperation.
