KYN28-12 Metalclad Modular Switchgear Compact Switchgear
KYN series metal-clad removable enclosed switch cabinet (called switch cabinet for short). It is applicable for power receiving and distribution in the 3.6-12Kv three-phase AC 50Hz single bus bar and single bus bar sectioning system. It has the functions of controlling, protecting and monitoring the circuit.
>>Ratings: system voltage 3.6kV, 7.2KV, 12KV, 24KV,rated current up to 4000A,
AC three phase 50/60HZ.
>>Application: mainly applicable in the power plant, substation, mineral enterprise to receive and
Distribute power with the functions of controlling, protecting and monitoring. It also can be
used in places where the frequently operations are in need.
>>Standard: IEC62271-200.
