KYN28 Series Withdrawable Metal Clad Switchgear - Reliable China Suppliers and Factory for 2.5-34.5kV Solutions
General
The switchgear meets IEC298, GB3906-91. In addition to be used with domestic VSI vacuum circuit breaker, it can also be used with VD4 from ABB, 3AH5 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.
