KYN28-12 is an indoor armored removable AC metal enclosed switchgear designed for three-phase AC 50Hz power systems. It is used for receiving and distributing electrical energy while providing control, protection and monitoring of electrical circuits.
The switchgear adopts a metal enclosed and removable structure, providing a practical solution for medium voltage power distribution systems where reliable operation, equipment protection and convenient maintenance are required.
KYN28-12 can be configured according to different power distribution requirements, including rated current and short-circuit withstand levels. It is suitable for industrial power distribution, electrical substations, commercial facilities and other medium voltage applications.
The product conforms to GB3906, GB/T11022 and IEC60298.
The switchgear uses a metal enclosed structure to separate the main electrical components and improve operational safety.
The removable switchgear configuration allows the circuit breaker unit to be withdrawn for inspection, maintenance and replacement.
Available rated current options include 630A, 1250A, 1600A, 2000A, 2500A and 3150A.
The switchgear supports short-time withstand current ratings from 20kA to 40kA according to the selected configuration.
Designed for indoor installation in medium voltage power receiving and distribution systems.
The configuration can be prepared according to the customer's single-line diagram, electrical requirements and project specifications.
