The KYN28-12 is an advanced indoor armored metal-clad switchgear that features a robust withdrawable (handcart) circuit breaker design. Engineered specifically for receiving and distributing 12kV three-phase AC power, this unit delivers exceptional reliability in protection and control operations. To maximize personnel safety and prevent operational errors, the system is fully interlocked for safe operation. The switchgear is structurally divided into distinct compartments—breaker, busbar, cable, and relay—which effectively isolate faults and simplify maintenance routines.
Manufactured under strict quality protocols, the KYN28-12 switchgear is fully compliant with IEC 62271-200 and GB 3906 international standards. Below is the core datasheet for bulk procurement evaluation:
